Small mammal monitoring at Fosheim Peninsula, Ellesmere Island

We monitor lemming abundance using four methods. (1) Dead trapping using snap-traps at 2 sites in early August; we cumulate 709 trap-nights at each site by trapping during 3 days (2007-2009). (2) Survey of lemming winter nests after snow-melt in late June using the line transect method (2007-2008). (3) Survey of lemming burrows within an area of 1 ha in late July (2008 only). (4) Survey of lemming runways using the line transect method in late July (2008 only).
