Beaver Library

This first webinar in the Association of State Wetland Managers (ASWM) and Bureau of Land Management (BLM) co-hosted six-part webinar series on beaver restoration details how beaver affect the land and the hydrologic impacts from loss of beaver through various hunting, trapping and removal activities. The webinar shared the role that beavers and beaver dam analogs (BDAs) can play in stream restoration.

Research and monitoring activities over a 45-year period on the Quabbin Reservation in Massachusetts have provided an opportunity to follow changes in numbers and dynamics of an unexploited beaver population.

Mike Callahan, President of the nonprofit Beaver Institute discusses beavers, their value, and how to successfully manage beaver problems when they occur. Mike also shares information on the Connecticut Beaver Initiative (CBI) a new grant program to help landowners resolve human-beaver conflicts nonlethally.

This landmark 20 year study compares traditional lethal beaver control versus nonlethal management methods in the town of Billerica, MA. A total of 55 beaver conflict sites were studied. Sites that were managed with nonlethal control methods cost taxpayers significantly less than sites that were managed with beaver removal, and provided millions of dollars of ecological services to the town annually that would have been lost with beaver removal.
