The document analyzes the American beaver's diet, finding it consists of 45.5% terrestrial and 55.5% aquatic vegetation. The proportions vary seasonally, with more floating leaf vegetation in winter and emergent aquatic vegetation in summer. Aquatic vegetation provides higher digestibility and nutrients. Beavers breed once per year and kits have highest mortality from August to March. Researchers observed beavers using logjams for escape cover and easier access to dens for kits. Beavers select habitats based on vegetation cover, stream gradient, bank slope, and proximity to other colonies.
