Book excerpt: Concern regarding reduced pelt harvests of long-tailed weasels (Mustela frenata) in the prairie provinces, together with research suggesting that this species was becoming rare in parts of Manitoba, resulted in the Committee on the Status of Endangered Wildlife in Canada (COSEWIC)placing it on the list of animals classified as threatened. This study was undertaken to determine whether there had been a decline in long-tailed weasel numbers in Manitoba, and if so, to identify possible causes and suggest management strategies to stabilize and encourage population growth of the species. The main avenue of data collection was a trapper questionnaire. Carcass analysis was used to collect biological (age, sex, size) and toxicological data. Conclusions were that long-tailed weasel numbers are much lower than 30 years ago, but that reduced pelt harvests are largely due to lack of trapper interest in the species commercially. The most probable causes of reduction in the numbers are habitat los.
