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
Aug 3, 2022 · We propose this method as a standardized way to monitor beaver population change which has potential to increase understanding of beaver population distributions and habitat selection if adopted more broadly.

HISTORY AND STATUS OF BEAVER POPULATIONS BY COUNTRY. Halley and Rosell ( 2002) provide information on beaver source populations, and details of location and size of reintroductions, before 2002. European distribution in 2002 is shown in Fig. 1; current distribution in Fig. 2.

Beaver growth over 10 years in the absence of limiting factors such as inadequate habitat, disease, predation, and human harvest, beaver populations are capable of very high rates of growth. Discover free geospatial public data, tools, and resources from U.S. Fish and Wildlife Service.
Population matrix models showed that survival of kits (1st year juveniles) and yearlings (2nd year juveniles) is the most critical factor in population viability. Survival of these age classes is partly dependent on the ability of beaver to successfully disperse and recolonize habitats.
ABSTRACT. Long-term research and monitoring activities on the Quabbin Reservation in west central Massachusetts have provided an opportunity to follow changes in numbers and dy namics of a local unexploited beaver, Castor canadensis, population over a 45-year period.

Feb 28, 2018 · More specifically, we developed a generalized intrinsic potential model that draws on remotely sensed measures of stream gradient, stream width, and valley width to identify where beaver could become established if suitable vegetation were to be present.
