Like most municipalities that are adjacent to waterways and water bodies, we face challenges in integrating the natural elements of a semi-aquatic ecosystem with urban uses. We recognize the great value that beavers provide to the ecosystem and work to ensure that beaver populations and the supporting ecology are cooperatively able to support each other.
One of the particular challenges faced by municipalities is effectively managing beaver activity and beaver populations. These mammals are incredible builders, constructing dams and lodges throughout the parks and waterway systems. In a completely natural setting, beavers are managed through natural selection, predators and harsh environmental conditions. In an urban setting, predators no longer become a major factor, environmental conditions are enhanced (food sources and water flow increases on urban streams and rivers) and as a result, over-population can and has become prevalent.
Beavers do present challenges to municipalities in that they can remove large numbers of trees, create safety hazards (from partially chewed through trees), can flood infrastructure and damage surrounding ecology through the damming of wetlands, rivers and creeks.
