Ecological Roles of Bears
Nitrogen Transfer & Soil Disturbance
"In British Columbia, grizzly bears feed on adult salmon when they return to their original rivers and streams to reproduce. Pacific salmon play an important role in the transfer of nutrients and energy from the marine to terrestrial environment [10][11]. Grizzly bears facilitate this by dragging salmon carcasses up from the river onto the land where they are consumed by the bears themselves and other terrestrial predators inserting an energy source into the terrestrial food web. As well the salmon carcasses decompose on the land, releasing nutrients (specifically high levels nitrogen) into the surrounding soils. These nutrients are necessary for productive soils that encourage plant growth, in turn facilitating high biodiversity. As well, as grizzly bears scavenge for roots and tubers in the fall they dig and turn up the soil. Homogenized soil is a major factor in unproductive land, thus turning up the soil increases productivity of the land, in the same manner that farmers will regularly till their soil. Increasing the productivity of the soil thus again increases vegetative biomass and facilitates plants biodiversity, which supports further animal biodiversity of both herbivores and predators." - University of British Colombia
Prey Regulation
Apex predators such as bears have strong top-down effects on their direct prey and associated species, so much so that their removal causes a trophic cascade. "Bears and wolves are the main large predators in the north-west ecosystem, and strongly regulate moose populations [8]. Without the regulation of bears and wolves, moose populations would boom and decimate the local vegetation, rapidly decreasing biodiversity and food sources for other herbivores, affecting the entire ecosystem. Besides from herbivore booms, loss of large predators can cause changes in prey behaviour and changes in the diets/behaviour of smaller meso-carnivores in the region [8]. Grizzly bears consume mammals, fish, invertebrates, and plants, thus their ecological effects extend to all areas of the British Columbian ecosystem, including both terrestrial and aquatic realms." - University of British Colombia
Seed Dispersal
"Grizzly bears are omnivores and consume both meat and vegetation. Bears will hunt animals, which provide a higher energy pay-off, when available or populations are high enough that they are energetically efficient to hunt, mainly in the summer. In the fall they typically dig for roots [7] and in the spring they scavenge for ripening fruits and berries [9]. Bears are part of a symbiotic relationship with the plants they eat in the spring, as they gain energy and nutrients from eating the fruit and then disperse seeds for the plants [7]. Specifically, grizzly bears have been recorded to be important seed dispersers for blueberries and buffalo berries, although they perform this important function for a wide variety of plant species. When bears disperse seeds after ingestion they release them in their feces, which provides a nutrient rich environment from which they grow. Thus grizzly bears play an important role not only in seed dispersal but also in creating an optimal environment for seed germination. This encourages plant growth and dispersal, which increases biodiversity and vegetation biomass for other herbivore’s consumption." - University of British Colombia
Threats to Bears
Human vs Wildlife Conflicts
Hunting
Hunting is still allowed, despite the scientific community warning about the consequences, and many countries already facing ecological decline because of bear's dwindling numbers or full extermination. In some countries bears are eaten, and even turned into sausages. In places like Asia they are kept in tiny cages and milked for their bile, a process that opens them up to deadly infections.
Feeding/Littering/Improperly Stored Food or Trash
This teaches bears to associate humans and our communities or camping areas with free food which can lead to deadly conflicts over time.
Habitat Destruction
Farming
We use almost half of Earth's habitable space for farming, and 77% of that land is used for livestock. When farmers feel their animals are threatened by predators like bears, they or the government often use deadly force to reduce conflict, despite scientific evidence showing that deadly control actually backfires, causing worse and more expensive problems over time.
Logging
Globally, land clearing for cattle is the #1 cause of deforestation, driving 5 times more deforestation for beef than any other industry. The 2 next greatest drivers are soy and palm, which are both major livestock feed ingredients (with growing markets), and the 4th greatest driver is the wood and pulp industry. In Canada, the USA's demand for toilet paper is driving deforestation of ancient Boreal forests.
Logging and land clearing not only destroys habitat in which bears and their prey shelter, but the very foods like berries that bears plus their prey rely on.
Habitat Fragmentation
Highways or freeways bisect bear habitat, reducing their genetic diversity. Solutions such as bear-friendly wildlife crossings will help both bears and other species improve their genetic variation, as well as reduce human/animal mortality rates along major roads.
Calls to Action
Level 1-3
Support a bear cub rescue or other bear conservation conservation programs. Check out our Organizations section to find a group near you.
Visit a bear sanctuary or national preserves for your next vacation. Some places offer tours, so please respect the bears by paying attention to the safety rules, and keeping them in mind when you see wild any animals.
Buy bear-friendly products, or find bear-friendly alternatives. For example we can reduce deforestation with simple diet changes, and installing bidets or bidet fixtures to reduce or eliminate toilet paper use.
Level 3-4
Contact your politicians to tell them bears need better protections from humans. That more should be done to end hunting and habitat loss.

Texas
Black Bears May be Returning to Their Native East Texas Habitat Including Liberty County "The black bears native to east Texas have experienced a habitat reduction of 80 percent due to property fragmentation, deforestation and unregulated sport hunting. As a result, their numbers in east Texas have dwindled to zero.
That matters because as apex predators, the bears once played an essential role in the balance of the east Texas ecosystem. Were they around, they might be keeping the exploding populations of deer and rampaging feral hogs in check.
That’s where the Texas Black Bear Alliance (TBBA) comes in. The nonprofit organization is working with the Texas Parks & Wildlife Department (TPWD) to explore eventually bringing black bears back to east Texas.
They estimate that through their efforts, the bears could be reintroduced here within the next 20 years."

Asia
Animals Asia: End Bile Farming "Animals Asia has been rescuing bears from bile farms for almost 20 years, and campaigns for an end to all bear bile farming in Asia.
We've saved just under 700 bears from the abusive bear bile farming industries in Asia. More than any other charity.
Most of the bears we rescue are defeated and broken after many years of abuse. They require many months or even years of extensive veterinary care and rehabilitation.
Animals Asia has two world-class sanctuaries for bears rescued from bile farms. One in China and one in Vietnam.
Sadly, bears used for bile farming cannot be released back into the wild. Most are captured as cubs or young bears and do not have the life skills to be able to survive. Furthermore, most bears we rescue are in very poor health.
But our sanctuaries enable the bears to live out their lives in peace, in the company of other bears.
We do everything we can to provide as natural and interesting an environment as possible where they can climb trees, swim in pools or simply lie on the grass in the sun."
Cambodia / កម្ពុជា។
Free The Bears: Cambodia Sanctuary "Located inside the Phnom Tamao Wildlife Rescue Centre, just outside of the capital city of Phnom Penh, Free the Bears sun & moon bear sanctuary was established in 1997. Following a spate of bear cub rescues, in 1999 the bear cub playpen was built and in 2000 facilities for adult sun bears were extended. A fully equipped Wildlife Hospital was completed in 2006 to help our bears and other species in need."
India / भारत
Free the Bears: India's Sloth Bears "For over 400 years, the sloth bear had been exploited by a nomadic tribe known as the Kalandars. Originally used as entertainment for emporers, 'dancing' bears eventually became entertainment for villagers and tourists. Mother bears were killed and cubs sold to the Kalandar people, who would then put a red hot poker through the muzzle of the baby bear, often without anaesthetic. A rope was threaded through the sensitive muzzle and then pulled to cause the bear to ‘dance’, a truly horrific practice and miserable life for the bear.
The first group of 25 rescued bears entered the Agra Bear Rescue Facility on Christmas Eve of 2002 and over the next seven years Free the Bears fully supported the Kalander Rehabilitation Program, providing seed money for more than 500 former dancing bear families to set up new livelihoods. They now have a stable community full of successful small businesses and their children have attended school & university for the first time ever - a wonderful success story.
... The rescued sloth bears are living in four large, natural sanctuaries operated by Wildlife SOS organisation, who we helped support for over 18 years."

Free the Bears: Vietnam Sanctuaries "Cat Tien Bear Rescue Centre was opened in 2008 inside Cat Tien National Park, in collaboration with the Forest Protection Department of Vietnam. Our first group of 9 rescued bears were greeted by the largest semi-natural habitat in Vietnam for rescued wildlife.
More bear rescues placed strain on the limited facilities and in 2017 we proudly opened the Cat Tien Bear Sanctuary and were able to move 16 moon bears to a huge forest enclosure (Bear House 1).
In March 2018 Bear House 2 was opened, giving 8 sun bears access to a large patch of forest and greatly reducing the pressure on the old bear rescue centre. In 2019 our Wildlife Hospital and Bear House 3 were opened."

The Andean Bear Foundation "(ABF) is a 501 (c) (3) non-profit organization that works for the conservation of the Spectacled/Andean Bear (Tremarctos ornatus), its habitat and associated species like the mountain tapir (Tapirus pinchaque). The work of the ABF has a strong focus on field research that looks to improve the knowledge about these species in the wild. With updated information about its population patterns the ABF will be able to develop or suggest better management practices for the species to be implemented by Ecuadorian environmental authorities and even neighboring countries where the species currently occurs.
Projects lead by the ABF depend mainly on donations and volunteering activities. However, resources obtained this way are generally scarce so it has been necessary to explore alternative funding sources. This eco-tourism project is a new way of funding which allows tourists to see wild bears and tapirs in their natural habitat."
