Small mammal monitoring on Herschel Island and Komakuk Beach
We monitor lemming abundance using three methods. (1) Absolute abundance estimation by capture-mark-recapture. This involves live trapping animals using Longworth traps on three, 2 to 9 ha grids (50 to 256 traps/grid) in wetland and mesic habitats; trapping sessions last for 2-3 days and are repeate...
