Biodiversity

INTRODUCTION

Biodiversity is a measure of diversity of species within a given area. Within an urban setting like South Salt Lake City, biodiversity can often be overlooked, despite being foundational to improving quality of life in the city. This study attempted to estimate the number and distribution of species within the city limits. This section also includes methods for how to increase this biodiversity within the city of SSLC.

OPTIMAL URBAN FOREST LOCATIONS FOR BIODIVERSITY

We considered three key factors at the intersection of biodiversity and urban forests: existing species richness, tree canopy, and patch/corridor composition. The map below combines all factors into a comprehensive map showing which areas of SSLC are the most fragmented, and thus would benefit most from the planting of trees. Darker shades indicate higher intervention needs, highlighting areas where increasing the urban forest would have the most significant impact.

Based on our observations, we conclude that the Northern most area of SSLC between I-15 and State Street would benefit most from an increase in the urban forest. By including these factors, we aim to create a more cohesive and connected urban forest habitat for all South Salt Lake City residents, both speaking and non-speaking.

SPECIES RICHNESS:

We used data collected by the citizens of SSLC to measure the number of different species in the city. Using the iNaturalist app the public has been taking pictures of various wildlife around them, having the app help to identify them. We were able to use this data to calculate the number of different species observed and where the observations were made.

TREE CANOPY:

We then used deep learning algorithms to identify tree canopy coverage in South Salt Lake City. We noticed a drastic divide between the East and West centered on State Street.

TREE RECOMMENDATIONS BASED ON BIODIVERSITY

Selecting trees for human health requires the consideration of three elements, habitat creation, contributions to patches and corridors, and emphasis on native species. However, in order to ultimately create a more cohesive and diverse urban ecosystem in SSLC, the city will need to also increase the area of green spaces and corresponding green connections. This green network would benefit both speaking (people) and non-speaking populations. For specific tree selection and information, see the Tree Selection page.

Miyawaki Forest

The Miyawaki method is an approach to replicate mature forests by planting a diverse mix of native tree species in a densely packed manner. It aims to mimic natural forest ecosystems and promote rapid growth and biodiversity in urban and degraded areas. It offers a promising approach to greening urban spaces, addressing environmental concerns, and enhancing biodiversity. Here’s how it can be practically applied in the city of South Salt Lake:

With dense and diverse planting, some of these ecological systems can be replicated throughout the city, providing important stepping stones for species as they move about the city. Tree species should be selected for their contributions to these ecosystems with an emphasis on native species. These would include common species like Hackberry, Oaks, and Maples, in addition to some evergreen species like pines and junipers. The tree list below is an inventory of trees that have the potential to benefit the urban forest needs and benefit the collective biodiversity of SSLC
