A short presentation from the Society of Wetland Scientists webinar in April 2021, given by Mark Beardsley of Eco Metrics, LLC in Colorado. Beardsley amplifies many voices of the beaver community in a presentation about how a lack of understanding of stream ecosystems has prevented human and beaver from reaching a complete state of collaboration. He describes in detail how active beaver wetlands create ecosystem services more abundant than wetlands without beaver.
A mathematical model for the dynamics of a harvested population of beaver (Castor canadensis) was developed based on the natural history and biochronology of the species. This discrete-time, deterministic model breaks the annual cycle of a beaver population into six periods and tracks the transitions between periods for forty sex/age classes.
This study was conducted to examine the social structure of beaver colonies occurring in the southeastern United States.
Linking Time Budgets to Habitat Quality Suggests that Beavers (Castor Canadensis) are Energy Maximizers
Study that tested whether beavers are energy maximizers by verifying the prediction that they allocate time to foraging activities independently of habitat quality in Kouchibouguac National Park of Canada in New Brunswick.
Foraging Decisions of North American Beaver (Castor canadensis) are Shaped by Energy Constraints and Predation Risk
Study to determine if beavers are able to assess the risk of predation by using two main cues: the distance from the water and the presence or absence of predator odors.
The article describes beaver behaviors and how they affect ecosystems, highlighting a university lake preserve in Kalamazoo where humans are learning to coexist with beaver. The author highlights the successful use of a beaver deceiver device in the preserve.
A brief overview of beaver history, ecology and management in North America.
Summary of the benefits of beavers, their conflicts with humans, and the policies and conditions that affect their survival
This study revealed that wolves rely on the poor eyesight of beavers to ambush them, but their success rate is not very high. Video included.
Educational article on the value of beavers by the Habitat Program supporting fish habitat conservation and restoration across Alaska, Washington, Oregon, California, and Idaho. Includes video and other helpful links.
