Abstract:
|
American marten are an important furbearer species in North America and have long been a part of the fur trapping industry throughout Alaska. Managers and trappers need methods to monitor and manage local marten populations such as an in-season harvest threshold that can indicate population status. We estimate the in-season harvest threshold using the entire season harvest from trappers throughout Interior Alaska from 2007-2016. A generalized linear model is used to estimate a relationship between the response variable of juvenile to adult female ratio and explanatory variable of proportion of juvenile. Trappers may check their own trap lines to compare with the in-season threshold, and decide to continue harvesting.
