Weasel population monitoring on Bylot Island, Nunavut

We monitored weasels using four methods. (1) Since 2012, known dens are visited periodically during the summer to determine the presence of adults, young, prey remains and collect behavioral observations. A brief description of all dens and the surrounding habitat is made when they are first found. (2) Since 2010, a network of 50 shelter boxes (20x40x60cm) is monitored twice during the summer (June and August). These wooden boxes can be used by weasels as shelters or to cache food (primary lemmings), which can provide an index of predation intensity. Prey remains cached inside boxes are also analyze to determine their composition. Automated cameras are sometimes deployed inside shelters with signs of use by weasel to record their activities. (3) Since 2008, opportunistic sightings of weasels are recorded to determine the minimum number of individuals present within the study area. (4) Since 2007, we survey lemming winter nests after snow-melt in early July using the line transect method. We record the number nests with signs of predation by weasels (lemming carcasses, nests lined with lemming fur) (see CCIN 624).
