The beaver is a semi-aquatic mammal known for its incredible engineering skills and unique adaptations. Found in freshwater habitats across North America, Europe, and Asia, beavers are best recognized for building complex dams and lodges using branches, mud, and stones. These constructions serve as protection against predators and provide a safe habitat for their families. Beavers' large, flat tails help them steer in water and slap to warn others of potential danger. They are herbivores, primarily feeding on tree bark and aquatic plants. Due to their industrious nature, beavers significantly impact their ecosystems by creating wetlands, which benefit various other wildlife species. Despite facing historical challenges from fur trapping, conservation efforts have helped stabilize beaver populations, allowing these fascinating creatures to continue contributing to the biodiversity of their environments.
