Microtus oecanomus
22 August - 1800 - Jogod Lake
Set out 20 traps in an area of about
300 square feet - 20 x 60 ft. at the outlet
end of the little lake on the mossy area above
Jogod Lake.
outlet lake
trap area
The vegetation is wet to damp sedge-grass
dwarf willow along margin of lake and
along stream outlet, bordered by an area
of upland rocky dwarf shrub-heat with
a bank 3-4 ft. high between the two
habitat types. Very frequent lemmings and
fresh new weas in this area.
2 August 1000 - Caught 4 M. oecanomus, specimen
members 274, 275, 276, 277,
1 August 1000 - caught one mouse, No 278.
5 August 1000 - no catch - traps removed.
Total catch of 20 traps for 3 "nights"
equals 5 for 300 square feet. This
was one of the shrewiest used looking
local areas that I have seen in the
Jogs area.
