Abstract: This project utilizes Mexico’s census data alongside historical records to trace native languages in the region. The resulting visualization presents a comprehensive map of Mexico's linguistic diversity. This mapping is crucial as many native languages are at risk of being forgotten. The research aims to benefit indigenous communities by fostering recognition and aiding in the development of strategies to support their cultural preservation.

Abstract: This map project presents the viewer with information about the top 25 countries that produce cacao and the top 25 countries that consume chocolate worldwide. Obtaining and analyzing data from FAO, I created both of these maps in ArcGIS and then transferred them to Adobe Illustrator to arrange them into a presentation. The maps and information presented to the viewer are enough for them to make connections and ask questions about the cacao-chocolate commodity chain, as well as to consider their own choices as consumers. I created this map to highlight the commodity chain behind a product that most people enjoy, and to raise awareness among the public.

Abstract: The completion of Dos Rios State Park and its surrounding rewilding projects aim to revert fallowed agriculture land to their historic role as natural flood plains for the Tuolumne and San Joaquin Rivers. Understanding regional flood hydrology will allow stake holders to assess the area’s additional role in groundwater recharge. Enhancing aquifer recharge is a desirable side benefit of River Partner’s restoration projects. Analysis of surface hydrology was conducted to determine the timing and geographic distribution of flood waters as the San Joaquin and Tuolumne Rivers experience a rise in stage, along with documenting paths and mechanisms of drainage as stages of the rivers decrease. Digital elevation models and land classification data were combined using ArcGIS Pro to generate a digital surface. The surface was input into U.S. Army Corps of Engineers River Analysis Software with hydrograph data from USGS, resulting in a temporal hydrologic simulation for flood waters.

Abstract: This project explores how citizen science can empower residents to engage in tree identification, verification, and mapping. Using Crane Park as a model, participants gained hands-on experience in urban forestry by utilizing ArcGIS Field Maps for geolocation and i-Tree services for ecological analysis. By incorporating open-source tools and expert consultation, the initiative promotes environmental literacy, strengthens public involvement in environmental stewardship, and encourages investment in urban green spaces.

Abstract: Noise pollution is harmful not only to humans, but also animals (especially birds and marine life). In this storymap, I will examine the locations, sources, and effects of noise pollution. Some of the sources of noise pollution are construction, transportation systems, and people, especially in urban areas. There are varieties of noise generation sources; traffic is a major source of noise pollution. This type of pollution has many harmful effects on citizens and animals. For example, for adults, noise pollutions leads to stress that could cause sleep disturbance, hearing damage, and risk of cardiovascular disease. For children, the negative effects include learning difficulties, and stress that could negatively impact well-being and motivation. For animals, noise pollution can affect the ability to hear mating calls, communication, finding prey, and avoiding predators. 

Abstract: Healthcare accessibility has historically been an ongoing challenge from both the Department of Veterans Affairs (VA) and the Veterans Healthcare Administration (VHA) within California, resulting in large gaps in available services for specific regions within the state. Limited research of at-risk areas and limited availability of services within California have been conducted. Using data from the US Census Bureau, the California State Government, the United States Department of Veterans Affairs, as well as both the Washington Office of Financial Management and the National Association of Insurance Commissioners, I created multiple map projections to reflect overall Veteran Population, Vet-to-Population Percentage, the areas within “accessible” and “emergency” range, and regions outside those ranges. Conclusions and data drawn from this research experiment multiple findings: Within California, Approximately 76.10% (18,258 Square Miles) of the state is within accessible range, or 22 miles of a VHA Facility; Approximately 95.60% (29,950 Square Miles) of the state is within emergency range, or 52 miles of a VHA facility; Approximately 19.60% (4,692 Square Miles) of California is within Emergency Range but NOT Accessible Range; And Approximately 4.39% (1,053 Square Miles) is completely outside Accessible AND Emergency Range.

Abstract: During the dictatorship of Efraín Ríos Montt, the Guatemalan government carried out a genocide against the Mayan Ixil peoples in the Guatemalan highlands. The Guatemalan military under Ríos Montt's direction carried out executions, rapes, forced enlistment, forced relocation, torture, disappearances, and other acts between March 23rd, 1982 and August 8th, 1983. The Mayan Ixil peoples were able to work with prosecutors to put Efraín Ríos Montt on trial. The judge would convict Efraín Ríos Montt of being guilty of genocide and crimes against humanity, the first time a country would hold their own leader accountable to such actions. Then ten days later the ruling would be over turned on a technicality. This StoryMap overviews the history of the the Guatemalan genocide and aims to increase awareness of the resistance efforts made by the Indigenous people of Guatemala.

Abstract: Events leading to the creation of the Department of Geography at CSU Northridge began in the Autumn of 1956 when climatologist Robert Durrenberger, became the first full time geographer in the Division of Social Sciences at what would be called San Fernando Valley State College. In 1957, he was joined by Robert Lamb, who had just completed his PhD at UCLA. Many others would arrive in the next few years, among them, Arnold Court. These three men, but most especially Robert Lamb, created a curriculum and physical environment that later permitted the department’s faculty to grow in size and undertake great projects. I will speak to the issue of just three of these, the California Water Atlas, We The People: An Atlas of America’s Ethnic Diversity, and the development of one of the most technically advanced geography curricula in California.

Abstract: In academe, geography occupies a precarious position, particularly in comparison with peer disciplines. Since the demise of Harvard in 1948, nine additional geography doctoral programs have vanished in leading American universities. Today, a majority of the 62 higher education institutions offering geography doctorates do not rank among the top 100 nationally ranked universities. Indeed, the onus of waving the geography banner has fallen increasingly upon community colleges and regional universities, and it is in these institutions of higher learning that California’s public institutions have played a vital role in ensuring the discipline’s future prosperity. Still, more can be done. For example, affiliation with the Visiting Geographical Scientist Program (VGSP) and World Affairs Council (WAC) can do much to enhance geography’s visibility. This paper offers insight, as well as a forum for discussion, with reference to strategies that can be adopted to elevate the status of the discipline.

Abstract: This paper describes the processes and progress from a community-led collaboration between local community-based organizations and the Enforcement Division of the California Air Resources Board to assess and address air pollution in South Stockton, particularly from heavy-duty diesel trucks. South Stockton is one of the most polluted neighborhoods in California’s San Joaquin Valley, one of the most disparate and polluted regions in the nation. Some of the most significant components integrated into this project include taking an equity-, justice-, and youth-oriented approach to community development that intentionally emphasizes a historical understanding of root causes of social and environmental injustices and provides pathways to workforce development. Including these elements has been essential in building the trust necessary to transform disparate power relations between the state and communities, and to put multiple ways of knowing into conversation with each other to co-learn and co-power solutions to air pollution in South Stockton.

Abstract: Nearly 20 years after the first research paper on Cannabis landscapes in Los Angeles was delivered at a CGS Conference, the topic is revisited.  Gone are both the “medical” and amateurism of the early 2000s. Today, most marijuana dispensaries in Los Angeles are run by professional staffs with large budgets for marketing. The typical place product marketing that characterized the early dispensary industry has been replaced gradually by a far more sophisticated set of design motifs that reflect the enormous profitability of some of the operations, and an evolution in the manner in which marijuana is marketed and consumed.  This paper features a photographic essay detailing the changes in the industry since the early 2000s, and an analysis of the current state of place product marketing of marijuana today.

Abstract: This paper looks at the devastating Jan. 7th, 2025 Malibu and Eaton Fires and puts them in perspective with earlier blazes in the LA Metro area. It covers some of the factors that make living in high risk zones an inevitable disaster. As with high risk flood zones, do we rebuild the same way over and over or are there smarter ways to deal with fire hazards? The paper includes some of the most memorable LA fires of the past and speculates about the future.

Abstract: This case study highlights methods of including young people in regional planning and implementation efforts such as California Jobs First. Workshops included participatory mapping/modelling, interactive focus group queries, and a framework for systems thinking and systems change. Designed around North State Jobs First’s focus on sustainable, equitable, rural economic development, the activities also centered participants and honored data sovereignty. Project purposes included: 1) providing opportunities for youth to share about their communities, likes, hopes, concerns, and proposed solutions; 2) setting the stage for potential further youth-led and intergenerational action; 3) facilitating learning experiences on community assessment, action, and related STEAM skills; and 4) piloting activities for possible replication. For this pilot, UC Davis Institute of the Environment partnered with Resources for Indian Student Education, Inc. (RISE) and MESA in Modoc County. Funding came from Sierra Institute for Community and Environment, co-convenor of North State Jobs First with Chico State.

Abstract: The island of Saint Helena, a British colony in the South Atlantic and one of the world’s most remote populated islands, has long fascinated travelers and explorers and is best known as the place of Napoleon’s final exile and death. One noted geographer and explorer, Quentin Keynes (1921-2003) (great-grandson of Charles Darwin and nephew of John Maynard Keynes), visited Saint Helena 74 years ago and published an article about it in The National Geographic Magazine in August 1950 entitled “Saint Helena: the Forgotten Island.” In this presentation, I contrast my own visit to Saint Helena in 2024, including repeat photography and discussions with residents, with that of Quentin Keynes (as well as some other visitors) and reflect on what has and has not changed since that time. Spoiler alert: almost nothing has changed!

Abstract: The development and maintenance of urban forests are influenced by both social and ecological factors, and urban resident opinions and preferences can influence public policies and urban forest management plans - with potential impacts on urban biodiversity. This paper uses a case study of the city of Fullerton, located in Orange County, California to examine resident opinions and preferences related to the city’s urban forest. Participants were surveyed to determine their priorities and concerns regarding Fullerton’s urban forest. Commonly cited concerns were related to tree maintenance and the amount of trees. The results demonstrate how residents in a mature suburban portion of a highly urbanized region perceive the urban forest, and these types of surveys can provide urban forest managers with valuable information to support urban forest management. More broadly, understanding resident opinions and preferences contributes to understanding the social dimensions associated with urban forests.

Abstract: Catastrophic wildfires are some of the latest signs that something has gone terribly wrong. Our dysfunctional relationships with the natural systems and cycles that rule our world has tragic consequences that are being played out in media spectacles every day. We are bombarded with such an extraordinary number of examples and teaching aides; they have become ordinary and routine. But instead of learning from them, we continue to repeat the same mistakes that help define a form of insanity. In this presentation, we will follow the before, during, and after of the wildfire disasters in Pacific Palisades and Altadena. We will use these and other “natural” disasters as evidence to show how “unprecedented” has become the new normal. And we will discuss our responsibilities in educating the general public about the science behind the scenes. Updates at https://rediscoveringthegoldenstate.com

Abstract: Roughly one-third of early California’s toponyms are Spanish in origin.  Although most were religiously inspired, many others were the results of early ‘adventures’ with animals. This paper examines several such encounters with native mammals, birds, and insects that led to permanent names on the land. Grizzly bears, coyotes, wild cats, and sea lions top the list of mammals, although in many cases their names were later changed to English. Bird toponyms included pelicans, seagulls, and eagles. Unpleasant encounters with fleas resulted in several toponyms, as did a single 1806 incident with a swarm of ‘butterflies’ that led ultimately to the naming of Mariposa Creek, Town, and County. Today, Mariposa celebrates this adventurous legacy with the Mariposa Butterfly Festival, including a butterfly parade, butterfly releases, and butterfly educational programs. Archival research suggests, however, that the Spanish explorers were not referring to butterflies at all, but rather swarms of noxious moths.

Abstract: Placing new housing in flood-prone areas could exacerbate California’s housing crisis, especially as flood risk increases statewide. We calibrated the USGS’s Land Use and Carbon Scenario Simulator (LUCAS) with sphere of influence maps, conservation easement and zoning data to project policy-informed urban growth. We intersected this model with Fathom’s climate-aware 2050 flood map to identify growth areas also at-risk for flooding. Approximately 27 cities with the greatest flood-susceptible growth are concentrated in Riverside, San Bernardino and Los Angeles counties. Flood-susceptible growth is primarily zoned as agriculture and planning areas, indicating potential land conversion and confirming cities’ existing development objectives. Growing cities predominantly surpassed the state’s required allocation of moderate and above average-income housing in the last planning cycle, yet failed to provide adequate low-income housing. Increased development in flood-prone areas threatens to create a new class of vulnerable communities, exacerbating existing vulnerabilities and abetting a cycle of environmental injustice.

Abstract: Networks come together to drive societal change and answer social problems. Complex problems cannot be fixed by a single entity and require a collective group of organizations in order to produce community-wide change. In hopes to understand the effectiveness of networks further, this study measured member organization connectedness in the Alliance. The Alliance is a network of organizations serving vulnerable children and families in the Greater Sacramento region. A likert-style survey was distributed to members of the Alliance network, measuring their self-reported level of connection with the Alliance and other members. Gathered survey data was analyzed and a number of visualizations were produced. Findings were shared via connectedness map of the Alliance network and a series of individualized results for their members. Assessment results revealed that interorganizational networks consisting of various organization types can mutually benefit each other in ways that are limited outside of this linkage.

Abstract: This thesis set out to find patterns in where talented baseball players have been originating over time. To accomplish this the hometowns of every player was mapped for the World Series between 1903-1932 followed by every All-Star from 1933-2024. Early patterns include lack of players from the American south likely due to societal and cultural differences between northern and southern states. Many early players who helped build this sport were first generation American’s whose parents immigrated from European countries during the major waves of migration. The most important change for this data was the destruction of the color barrier by Jackie Robinson in 1947. Following this players originating from countries all over the world begin to appear. The countries these players came from were dependent on multiple factors. These factors proved to be quite consistent at all scales from cities around the United States to countries around the world. 

Abstract: Open Government Data (OGD) can play a key role in the sustainability planning of cities. OGD can enhance this effort by fostering transparency, encouraging public participation, and facilitating collaborative decision-making. This paper examines OGD’s role in relation to OGD policies, general plans, and sustainability and climate action plans. The focus was on the 19 U.S. cities ranked in the 2024 Sustainable Cities Index Report. The study employed document review, content analysis, descriptive statistical analysis, and interviews with OGD and planning experts. First, I examined whether OGD initiatives met the intentions of OGD policies and the expectations of experts. Second, I reviewed the content of cities’ plans to determine how they align with the city’s OGD  initiatives. Third, I identified how OGD correlates with cities doing well at sustainability planning. Finally, I framed potential strategies to address OGD based on interview data. Overall, OGD initiatives are still in the infancy of being broadly useful. OGD policy focuses on government transparency, while experts highlight its importance in promoting public participation. OGD was defined in the plans of seven cities, serving as a data repository, tracking city progress, and providing evidence to support decision-making. 

Abstract: The transformation of military bases into civilian spaces leaves behind more than abandoned infrastructure—it reshapes ecologies, social landscapes, and historical memory. In Orange County, California, the closure of Marine Corps Air Stations El Toro and Tustin has given rise to new urban developments, yet their former perimeters have also become unexpected refugees for raptors. Once displaced by military aviation, red-tailed hawks, Cooper’s hawks, and barn owls now reclaim these altered environments, exploiting greenbelts, landfills, and repurposed hangars as hunting grounds. This paper examines how the resurgence of raptors in post-military landscapes reveals deeper tensions between history, conservation, and urbanization. As apex predators, raptors thrive in transitional spaces, yet their increasing visibility generates conflicting public perceptions—celebrated as natural pest control yet sometimes viewed as intrusive. Their presence complicates narratives of environmental recovery, challenging assumptions about what is “wild” versus humanengineered. Through an anthropological lens, this study explores how post-military landscapes remain contested, both in memory and in ecological function, as raptors and humans continue to renegotiate the boundaries of shared space.

Abstract: This presentation explores the hydrosocial history of the San Diego Creek Sub-Watershed in Orange County, California, emphasizing how this watershed was created not through a conservation master plan, but out of necessity—shaped by urban expansion, infrastructure failures, flood events, and regulatory pressure. Using the hydrosocial cycle, political ecology, and urban ecology frameworks, the study traces four historical configurations: Indigenous-Rancho water relations, agricultural intensification, urbanization and channelization, and environmental restoration. Archival sources, legal records, and environmental planning documents reveal how the 1968 channelization of San Diego Creek fundamentally altered regional hydrology and birthed a new sub-watershed. The formation of the Irvine Ranch Water District and the restoration of the San Joaquin Marsh illustrate how both top-down governance and bottom-up activism influenced water management outcomes. This case demonstrates that watershed systems are socio-natural hybrids shaped by necessity, contestation, and adaptation—not idealized environmental design—offering lessons for urban water governance and resilience planning.

Abstract: AI and climate literacy are important skills to build as both AI usage and climate misinformation are on the rise in the US and beyond. This is in part due to the rapidly developing nature of generative AI models like ChatGPT and the increasing polarization of the topic of climate change. As both current and future educators, there is a need to develop educational tools and approaches to engage students with these challenges and help students develop their climate and AI literacy. In this talk, I provide an overview of an assignment designed to tackle this challenge, including assignment design, context, and student takeaways. In addition, I will discuss ways I can see this lesson being improved upon for future iterations of this class activity.

Abstract: This article examines the cultural significance of fifty-six public murals in downtown Modesto, California. It categorizes the murals into three themes: Agrarian Heritage, reflecting the city’s agricultural past; Retro Americana, which connects to cultural icons like George Lucas’s ‘American Graffiti;’ and Cosmopolitan Aspirations, representing contemporary initiatives to redefine and curate Modesto’s identity. The study identifies recurrent imagery to discern the shared iconography that shapes Modesto’s past and present narratives. The analysis suggests that public art in Modesto serves as a medium for community identity and collective memory, while primarily contributing to economic engagement and urban revitalization, thus influencing the city’s sense of place and identity.

Abstract: This paper introduces Environmental Equitability Index (EEI), an equation based metric created to evaluate disparities in environmental quality across Sacramento neighborhoods. By integrating income, urban canopy coverage, pollution exposure, and walkability, the EEI quantifies spatial inequities in environmental access. Using this model, the study looks at both short-term and long-term urban canopy growth scenarios to assess their impact on neighborhood-level equity. Results show that greening efforts in low-EEI areas can produce equity gains exceeding 200%, showing the important impact of investments in historically underserved communities. This project shows the role of green infrastructure in closing environmental equity gaps. The EEI offers a data-driven framework for guiding urban planning and policy decisions in Sacramento and beyond.

Abstract: Although the United States was founded by immigrants, time and again, nativist populism has risen, often characterized by the frequent and unjust attribution of blame upon immigrants for economic hardship, crime, and uncomfortable cultural shifts in society. The first Trump administration fueled xenophobia, particularly with reference to targeting immigrants from across its southern border as the source of America’s struggles. A week after Trump signed the executive order, “Protecting the American People Against Invasion,” ICE arrested nearly 1200 undocumented people in one day; although the administration asserted that priorities would be placed on immigrants who have committed serious crimes, half had no criminal record. The fear among those living in immigrant communities has surged. Yet the fiscal impact of immigration to the US economy is beneficial. Examination of this issue provides insight with reference to the imperative role both documented and undocumented immigrants play in contributing to the US economy.

Abstract: Having been hit hard by COVID-19, the urban development of Merced, California has led to an imbalance: Downtown and Central Merced are experiencing neglect and decay while other areas are heavily invested in and sprawling. With these planning initiatives being controversial at best, residents feel disconnected from the overall identity of the city. But, littered between the dilapidated buildings and boarded up businesses downtown lies immense creativity in the form of public art. This study identifies the three categories of public art seen in Central and Downtown Merced and discusses how it showcases the history, culture, and ecology of the area. This study shows how this public art has reinforced a sense of community and place between Mercedians and can give them more control over their environment as talks of revitalization projects commence.

Abstract: The California High-Speed Rail (CAHSR) project is poised to transform travel in the state, but its completion is uncertain due to fluctuating funding and political support. This study investigates land use changes around the CAHSR stations in the Central Valley since 2015, using image segmentation for land classification at five-year intervals. The analysis was conducted on the Google Earth Engine platform. The results show minimal changes in urban infrastructure, such as built-up areas and pavement, near the stations in Hanford, Madera, and Bakersfield, while significant land use changes were observed in Fresno and Merced. These findings provide insight into the progress of the CAHSR project and highlight the varying levels of urban planning and development occurring around the stations in anticipation of the rail system’s completion.

Abstract: Over the years, researchers have examined the impact of systemic racism in the form of redlining in cities across the United States. Frequently, these studies focus on major cities with fewer results being presented for second-tier cities. Absent from much literature is a closer examination of the role racially restrictive covenants played in the temporospatial distribution of select populations in second-tier cities. Repeating a unique methodology recently used to analyze a second-tier urban population in the Midwest, this study explores the evolution of the population of Stockton in terms of demographic and socioeconomic development over the last 50 years. A comparison of census tract level variables against the backdrop of redlined maps and restrictive covenants of selected neighborhoods in Stockton, California reveals the extent of government influence on housing and settlement patterns. More significantly, this study reveals the legacy impact specifically of restrictive covenants on a local scale.

Abstract: The rising fatalities of migrants along the U.S.-Mexico border has become a focal point of political and social debate. This project examines migrant deaths in relation to U.S. border enforcement policies, focusing mainly on the Arizona border. It maps the man-made corridors created by these policies over the past two decades, exploring whether increased border security has pushed migration routes into more dangerous terrain, thereby contributing to higher fatality rates. By integrating geography and policy, this study seeks to raise awareness of the systemic factors behind migrant mortality and provides insights for future research and policy reform.

Abstract: Kerr Park, designated as a wilderness area by California, has undergone significant ecological restoration. Historically impacted by gravel quarrying and other disruptive activities, this park's environment, particularly the Stanislaus River ecosystem, has been severely altered. Restoration efforts have focused on reviving the native cottonwood tree populations and Central Valley Chinook Salmon. This study examines the cottonwood demography, comparing the current tree populations to traditional survivorship curves to assess the restoration's effectiveness. Our findings aim to provide insights into the health of these trees and set a benchmark for future ecological recovery evaluations.

Abstract: Climate change is heavily impacting America’s national parks and protected landscapes. This research focuses on how Alaska’s national parks are being impacted through an environmental lens, and how the parks are adapting to the changes. Four major results of climate change in Alaska’s eight national parks have been found, using quantitative and archival research methods. The results include rising temperatures, boreal forest fires, landslide risks, and an impact on both environmental ecosystems and the ecosystems of the native people of Alaska. The National Park Service has outlined four strategies to respond to climate change, including understanding the science behind climate change, adapting to changing climate conditions, mitigating the cause in the parks, and communicating about the issue. This research intends to discover what the future of these protected landscapes will look like due to climate change.

Abstract: Chinampas are an ancient agricultural system that once sustained populations of hundreds of thousands of people in pre-colonial Mexico. Spanish colonization led to the drainage of the once mighty lake systems in the Mexico basin, drastically altering the landscape and water systems and causing the near extinction of this robust farming method along with its Indigenous stewards. This paper explores the recent resurgence of Chinampa system agriculture in Xochimilco in response to food insecurity exacerbated by the COVID-19 pandemic. It draws connections between the colonial-era practice of “reclamation” of natural water systems in the Mexico City Basin and similar practices in California’s Central Valley, particularly the draining of Tulare Lake.  It also considers the potential for introducing Chinampa farming in the Central Valley with a focus on identifying ideal locations and how it may be used to enhance food security and support Indigenous food sovereignty in the region today.

Abstract: Photodegradation in terrestrial ecosystems is the process by which solar radiation breaks down organic matter and contributes to decomposition of plant biomass. Photodegradation can have direct and indirect effects on organic matter cycling. Photodegradation can occur through direct photooxidation of plant matter, and photodegradation can also occur through indirect facilitation of decomposition by making plant matter more available for microbial degradation. Thus, the direct and indirect effects are moderated by a range of environmental factors, including temperature and moisture. Although photodegradation could be expected to occur primarily in arid ecosystems where microbial processes may be limited by water availability, research from our group and others suggests that photodegradation is a widespread phenomenon that can account for approximately one-quarter of plant litter decomposition across a range of locations. This poster will present a summary of recent research and suggest ideas for future work.

Abstract: In February 2025 I lead a workshop with the Natural History Museum of Los Angeles County to teach community scientists and community organizers how to analyze iNaturalist data using R.  iNaturalist is a program that encourages people to document the biodiversity around them. With 230 million observations, iNaturalist is one of the biggest sources of biodiversity data.  Many iNaturalist projects encourage community scientists to collect data, but leave data analysis to “real” scientists. Our goal was to teach community scientists some basic skills so that they could look for answers to their own questions. We believe it is important to teach community scientists that their voice and questions matter.  During the first class, we covered how to filter iNaturalist CSV data, create maps, and create charts using R. During the second class, each attendee presented their analysis. This presentation will cover what we learned from teaching the workshop.

Abstract: This project explores the use of deep learning models to map homeless encampments in Eureka, CA, with a particular focus on areas within flood zones that may potentially impact the coastal ecosystem of Humboldt Bay. The project critically examines the ethical implications of using artificial intelligence in this context, particularly with respect to the privacy and dignity of homeless individuals. The study balances technological advancements in geospatial data analysis with the need for responsible and humane applications of AI, ensuring that the potential environmental impacts of encampments are addressed without stigmatizing vulnerable communities.

Abstract: The Baltic Sea ecosystem is increasingly threatened by the intensification of harmful algal blooms (CyanoHAB), primarily caused by filamentous blue-green algae (Cyanobacteria). These blooms contribute to eutrophication, a process of excessive nutrient enrichment, due to their ability to fix nitrogen. Monitoring the frequency, intensity, and distribution of these blooms is challenging because of their large spatial variability. This project investigates the spatial variation of toxic Cyanobacteria in the Baltic Sea using multispectral analysis with MODIS (AQUA) satellite data, the Cyanobacteria Index (CI), and the Random Forest machine learning algorithm. The goal is to visualize and analyze the spatial variability of Cyanobacteria blooms and assess their ecological impact on the Baltic Sea ecosystem.

Abstract: This map examines the relationship between wind speed and fire damage in major California wildfires from 1995 to 2025, with a focus on the 2025 Palisades and Eaton Fires. Inspired by the extreme conditions of these recent events, the project investigates whether higher wind speeds correlate with greater fire damage. Wind speed is measured by both sustained winds and gusts, while fire damage is evaluated through acreage burned, structures destroyed, mortality rates, and estimated economic loss. Data is sourced from CAL FIRE, the National Weather Service (NWS), and NOAA. By visualizing this data, the map seeks to reveal patterns that may inform future fire preparedness and response strategies in California.

Abstract: As global temperatures rise, the geographic ranges of disease vectors are shifting, increasing or introducing new health risks to previously unaffected regions. This poster map examines how climate change is driving the northward expansion of two important vectors: the nine-banded armadillo (Dasypus novemcinctus) and mosquitoes (Aedes aegypti and Aedes albopictus), which thrive in warm, humid environments. The nine-banded armadillo, a natural vector for Mycobacterium leprae (the bacterium responsible for leprosy), has moved into areas with historically cooler climates. Likewise, warming temperatures have allowed mosquitoes capable of transmitting dengue, malaria, and West Nile virus, to extend their geographic range. This project visualizes the intersection between human populations and these vectors using spatial data and environmental overlays. Understanding these shifts is essential for predicting future outbreaks, informing proactive public health responses, and emphasizing the need to address climate change as a root cause of emerging infectious disease threats in a warming world.

Abstract: Climate change is rapidly altering water-centered landscapes in America’s national parks. This research focuses on how Glacier, Hot Springs, and Everglades National Parks are each experiencing water-related impacts from climate change, and how the parks are responding. Through environmental analysis and secondary research using scientific and government sources, this project identifies three major results of climate change: glacial retreat and permafrost thaw in Glacier, disrupted geothermal water flow in Hot Springs, and sea level rise and saltwater intrusion in the Everglades. These changes threaten native ecosystems, biodiversity, and long-term park sustainability. The National Park Service and affiliated agencies are working to monitor these changes and mitigate their effects through conservation strategies such as habitat restoration, invasive species control, and localized emission reduction efforts. These insights are key to predicting how climate change will continue to affect water-centered landscapes and for informing targeted conservation responses that aim to preserve ecological function.

Abstract: Recent research highlights the role of arbuscular mycorrhizal fungi (AMF) in plant growth, yet few studies examine their impact on restoration success. This study investigates whether AMF influences plant growth and survivorship by measuring plant height, canopy width, and stem/trunk diameter in AMF-treated and non-treated fields. The study focused on Quercus lobata, Rosa californica, and Salix goodiingii. Results showed no significant differences in most growth parameters, but Rosa californica exhibited increased stem diameter and height in AMF-treated fields, while Quercus lobata had greater trunk diameter in non-treated fields. Survivorship analysis indicated AMF inoculation plays a role in plant survival. These findings suggest that while AMF may not universally enhance growth, they can affect specific traits in certain species. Further research is needed to determine the conditions under which AMF benefits plant growth and survival.

Abstract: In order to navigate the changing climate and its effect on the Fullerton Arboretum’s variety of vegetation, the Climate Impact Assessment Team is using the Climate Assessment Tool (CAT), International Plant Sentinel Network’s (IPSN) Plant Health Checker, article research, and various soil sampling techniques to determine which trees are currently or projected to do poor or well in the next fifty to ninety years. In ongoing research efforts, trees such as peach (Prunus persica), various oaks (Quercus Lobata, Quercus douglasii, Quercus agrifolia), and redwood (Sequoia sempervirens) have been projected to not make it to 2050 even when limiting greenhouse gas emissions. Alternatively, species such as the Desert Ironwood (Olneya tesota) and the Socotran pomegranate (Punica protopunica) are projected to thrive in the arboretum as temperatures rise. 

Abstract: This GIS-based project investigates spatial correlations between seismic hazards and socioeconomic vulnerability across two of California’s most populous regions: Los Angeles County and the San Francisco Bay Area (San Francisco, Alameda, Santa Clara, and San Mateo counties). Using liquefaction zones and Quaternary fault data alongside census tract per capita income, the project identifies communities where geologic risk and economic disadvantage intersect. A hazard overlay analysis reveals patterns of disproportionate exposure that could inform targeted outreach, resilience planning, and mitigation efforts. Building on previous work centered in Southern California, this expanded analysis invites comparative insight and underscores the importance of integrating socioeconomic variables into seismic risk assessments.

Abstract: This study investigates burn severity and vegetation regrowth following the 2021 Monument Fire, which burned 223,124 acres in Northern California. Using remote sensing techniques and geospatial analysis, the research assesses the fire’s impact and the subsequent two-year recovery in Trinity County, a fire-prone region with dense forests. By analyzing satellite-derived vegetation indices, such as the Normalized Burn Ratio (NBR) and Normalized Difference Vegetation Index (NDVI), this study identifies recovery patterns across varying burn severity zones. Findings reveal differential recovery rates influenced by burn intensity, topography, and climate, with some areas showing significant vegetation rebound while others exhibit prolonged degradation. This highlights the complex ecological impacts of severe wildfires. The study emphasizes the need for long-term monitoring of fire recovery to inform land management strategies aimed at mitigating wildfire effects in similar ecosystems.

Abstract: Petroglyphs are a form of rock art produced by carving or picking techniques. In the study of ancient societies across Michoacán, México, petroglyphs offer an important and non-invasive way to understand patterns of settlement and land use. Petroglyphs often marked sacred or important places, making their contexts especially important for analysis and conservation. By analyzing variables such as elevation, aspect, distance from natural resources, and proximity to permanent settlements, it is possible to identify spatial patterns in petroglyph design and location. This study draws on recent research from other regions in the Americas to inform my methods in Michoacán. I expect my research to contribute to the development of new conservation strategies for protecting and interpreting and petroglyphs

Abstract: This project analyzes the economic and political context of President Trump's executive orders regarding water management in California, with a particular focus on the San Joaquin Valley. Using a combination of contemporary news articles, government reports, and census data, the project examines the influence of political and economic interest groups on water management policy. By identifying patterns in how these groups shape policy decisions, the project aims to better understand the intersection of political interests, economic pressures, and environmental management in California's water policy landscape.

Abstract: Using Landsat 5 TM and Landsat 8 OLI satellite imagery, a 30-year analysis (1986–2019) of urban growth and surface temperature in the Banderas Bay–Puerto Vallarta tourist zone was conducted. Rapid urbanization has altered local climate patterns, creating an urban climate. Urban expansion was digitized every five years using Google Earth’s time series tool. Three indices were calculated: NDVI (vegetation), NDWI (moisture), and NDBI (built-up areas). Land Surface Temperature (LST) was estimated through thermal bands. In 1986, urban areas covered 21 km², increasing to 97 km² by 2019. Urban zones showed temperatures exceeding 35 °C, while vegetated areas remained between 20–25 °C. The study confirms a direct link between urban growth and rising surface temperatures. Projections suggest that by 2060, temperatures could increase by up to 3 °C, intensifying urban heat islands, reducing water availability, and heightening public health risks—trends already observed in cities globally.

Abstract: This research compares two distinct cropping systems: an herb garden and a sunflower garden to examine how canopy structure influences light transmission. Light availability was calculated using a light meter to measure Photosynthetically Active Radiation (PAR) at both ground level and mid-canopy. The Leaf Area Index (LAI) was calculated to determine canopy density. The results showed that the herb garden had a denser canopy, allowing only 21.4% of PAR to enter, whereas the sunflower garden, which had a taller and more open structure, allowed 82.7% of PAR to reach the ground. This study is an example of how a human cropping system captures light energy.

Abstract: Salicornia pacifica, or pickleweed, is a halophyte native to California wetlands. As a halophyte, it is adapted to saline conditions and the adverse impacts that come with living in these environments, including osmotic and oxidative stress. My goal is to determine how salinity affects the chlorophyll content of pickleweed in order to project the potential impacts of climate change on pickleweed growth. The approach I used was to grow pickleweed under greenhouse conditions in control, low, and high salinity irrigation treatments and to measure chlorophyll content after ten months. The control group was found to have 31% more chlorophyll per gram of fresh weight than the low group, and 39% more than the high group. The results suggest that pickleweed will have reduced chlorophyll content in the future due to increasing salinity of wetland soils as a result of climate change, implying lower productivity and ecosystem function of these wetlands.

Abstract: Palm oil is an essential ingredient in the production of a wide assortment of everyday products, with more than half of all packaged goods in grocery stores containing the substance. Indonesia is the worldwide leader in palm oil production, currently being responsible for 56% of the world’s palm oil exports. While monoculture palm oil plantations are a major source of profit for the region, the devastating impact of converting old growth forests to farms on plant and animal populations cannot be overlooked. By comparing the growth of the palm oil industry with deforestation rates in Indonesia, a correlation between the two becomes clear. Recent legislation has attempted to combat this rise in deforestation driven by plantation development, but continued assessment of the circumstances is required.

Abstract: This study explores the effects of a tree canopy on light transmission and ground cover across four transects. Light intensity was measured using a lux meter at 2-meter intervals, and ground cover types were categorized as bare ground, herbaceous, or woody cover. Results revealed significant reductions in light under the canopy, with variations across transects due to directional exposure and canopy density. Ground cover diversity was highest near edges, while shaded areas favored woody and dry herbaceous vegetation. These findings highlight the tree’s role in shaping microenvironments, offering insights for optimizing tree placement to enhance biodiversity and agroforestry practices.

Abstract: This study investigates potential arsenic contamination at UCSB’s “Wetland Space,” a site designated for Indigenous stewardship and located near historical military infrastructure, including WWII-era Underground Storage Tanks (USTs) and a swimming pool that is known to leak poolwater. While previous nearby testing revealed elevated heavy metals, the site itself remained untested despite cultivation of culturally significant edible and medicinal plants. To assess potential contamination and movement of heavy metals through the ecosystem, surface and subsurface soils across multiple spatial zones were sampled, along with ingestible tissues from Cattail, California Rose, and Yerba Mansa. Samples were processed and analyzed using Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) to quantify elemental concentrations. This research aims not only to evaluate contamination, but also to understand pathways of toxic metal uptake from soil into plant tissues, informing safety, restoration , and Indigenous food sovereignty efforts.

Abstract: Community gardens are vital in providing healthy, fresh produce to people in urban communities. However, urban soil may not be healthy for plant growth due to the modification of the natural soils by urbanization processes. This study examines soil health in a community garden by comparing selected soil properties in a local community garden to a natural oak grove, which serves as a control. Important soil health parameters, including soil texture, soil compactness, pH, electrical conductivity, and infiltration rate, were measured across both landscapes. The soil texture in the community garden is similar to that of a natural plot, although the natural plot had more sand fraction. Higher average pH and electrical conductivity values were observed in the community garden compared to the control plot, while soil compaction was lower in the community garden. The infiltration rate was higher in the community garden compared to the oak grove. The results suggest that citizen amendments of urban community gardens may improve some soil physical health parameters and soil productivity.

Abstract: My poster is on the Tuolumne River Watershed and the future of the area and how we can make sure the watershed stays how it is for wildlife, agriculture, and municipalities. I will use examples of Salmon, Trout, Precipitation Records, and vegetation history to show how water has been reduced over the last fifty years and how we can prepare for the future to ensure preservation. I will also show the negatives and positives of the many reservoirs in the watershed and how although they differ from the natural gorge it is necessary for people living in the state and it is still a biodiverse area just in a different way that also benefits people.

Abstract: Fires in the Western United States are becoming more frequent and more severe. It is imperative that we ascertain what influences the magnitude and spread of these wildfires. In this study, we attempted to better understand how weather plays a role in the size and intensity of wildfires in California, Oregon, and Washington. We analyzed the total area burned and burn severity versus humidity, wind, and air temperature anomalies for 100 of the largest wildfires across the three Pacific States to further our understanding of how weather and wildfires are related. To accomplish this, we obtained datasets from Landsat burn severity classes and total burned area, plus humidity, wind, and surface temperature at the center of each fire using Google Earth Engine and the daily data retrieved from European Centre for Medium-Range Weather Forecasts ERA5 climate reanalysis. We then utilized multiple linear regression and correlation analysis to determine how much of the variation in the total burned area and burn severity across these fires can be accounted for by weather anomalies. Moving forward, we hope to conduct a more focused study on how these weather variables played a role in specific fires throughout California, Oregon, and Washington.

Abstract: 3D printing means a lot more to an individual when it plays a useful role in their lives. This display in-captures the use of a Fab Labs in making useful objects and models affordably. This aeroponic system is good for small spaces like dormitories and experimental projects allowing you to grow vertically, saving space as well as saving you money by building one using a 3D printer when compared to an online purchased version. In building this system there was much to learn, from understanding the nutrients, to proper lighting indoors. Overall, trial and experiments with this indoor aeroponic tower has led me to change the system this time around. I have created mounts for lighting and added a turntable underneath the system in order to provide more even lighting. 3D printing can also be used to develop terrain modeling.

Abstract: Plant density surveys are useful in a wide range of environmental projects. The purpose of this study is to evaluate the use of sUAVs (small unmanned aerial system), as well as pretrained object detection models, in the evaluation of brush density in the Mojave Desert. Students from Pasadena City College conducted a plant density survey in the Mojave Desert using phone-based GNSS receivers, and the survey site was photographed by a sUAV. Photograph data was then processed and analyzed using Esri’s ArcGIS Pro software. We hope to see similar density statistics between the two data collection methods. This outcome of this project will help determine the usefulness of sUAVs for future plant survey projects.

Abstract: This project examines how the Arcata Marsh and Wildlife Sanctuary in Humboldt County, CA, serves as a "third place" for the local community. A "third place" refers to social spaces where people gather outside their homes and workplaces, fostering community interaction and well-being. This study uses semi-structured interviews and observational surveys to assess who uses the sanctuary and how the site facilitates this role. The free, outdoor nature of the sanctuary makes it particularly accessible to a wide range of individuals, encouraging diverse community engagement. The project highlights the significance of the Arcata Marsh as a welcoming, open space where people connect, relax, and engage in recreational activities.
