Abundance of insectivores (Soricidae) declined dramatically during the undersnow period 2005/2006, and they were not captured in snap-traps (300 trap-days in early June and late August). Their relative density in captures using cylinders was 0 animals/10 days in June, 13.8 animals/10 days in July and 42.0 animals/10 days in August, with the Common Shrew always being the dominant species.
Abundance of voles was low in spring, when they were absent in snap-trap catches, but increased in July and reached 0.7 animals/100 trap-days in late August. Considerably more voles, predominantly Short-tailed Voles (46.2%), were captured using cylinders with a relative density 10 animals/10 days in June, 0 animals/10 days in July and 16.0 animals/10 days in August. Wood Lemmings were not captured in 2006.
Similarly to the previous year rains and high level of ground water adversely affected rodent capture efficiency. Precipitation occurred on 50% of days in June, 68% in July, 32% in August and 53% in September.
High abundance of voles, primarily Microtus spp., was recorded in September - October 2006 in Kandalaksha, Luvenga and Kolvitse. Animals, also running on snow surface, were seen in the vicinity and inside these settlements until December. We captured 23 Common Voles in Nizhnyaya Kandalaksha area.
