Solving Beaver Flooding Problems through the Use of Water Flow Control Devices

This paper describes the social and ecological context for current beaver problems, how WFCDs function, gives installation and maintenance tips, and presents results of two surveys that assessed the effectiveness of WFCDs in alleviating beaver flooding problems in Connecticut and Massachusetts.

Evaluating landowner-based beaver relocation as a tool to restore salmon habitat

Relocating American beavers (Castor canadensis) from unwanted sites to desirable sites where damage exceeds stakeholder capacity) has been posited as a method to enhance in-stream habitat for salmonids in the Pacific Northwest.

A study of 482 flow devices by Beaver Solutions LLC in Massachusetts demonstrated that flow devices are the Best Management Practices for beaver dam flooding problems. Published by the Assoc. of MA Wetland Scientists, 2005.

Project: Hydrological Impact of Beaver Habitat Restoration in the Milwaukee River Watershed

A comprehensive study evaluating how restoring beaver dams could significantly protect the city of Milwaukee from future flood vents and the significant cost savings of this nature-based management approach versus traditional flood prevention engineering.

Billerica Municipal Beaver Management Program Analysis, 2000 – 2019

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.
