The beaver population in Yoho National Park declined primarily due to habitat loss and changes in land use practices, including logging and road construction that disrupted their natural habitats. Additionally, increased competition for resources and predation from species such as wolves and coyotes may have contributed to their decline. Conservation efforts and habitat restoration are essential to support the recovery of beaver populations in the park.
The decline of the wolf population in Yellowstone National Park led to an increase in elk and deer populations, as there were fewer natural predators to keep their numbers in check. This surge in herbivore populations resulted in overgrazing of vegetation along riverbanks, which negatively impacted the habitat for beavers. Beavers rely on the presence of healthy riparian vegetation for food and building materials; thus, their population declined as their habitat deteriorated due to the increased herbivory.
The beaver population in Yoho National Park experienced a resurgence due to successful conservation efforts. These efforts included habitat restoration and reintroduction programs which helped the beavers thrive in the park once again.
Without a healthy population of wolves, elk and deer (and other deer species) habitually graze on aspen, willow, and cottonwood sprouts, preventing young trees from growing into mature trees. This essentially starves the beavers, causing them to either die off, or go elsewhere. It's all part of the trophic cascade.
