A return trip on a quadbike was conducted across the Meinypilgyno Ridge, the main axis of the Koryak Highlands in its north-eastern part, from 28 August to 1 September, in search for a convenient route to Mainits Lake.
Microtine rodents were not recorded and signs of their activities were very rare on the southern macroslope of the ridge, in the valleys and upper floodplains of the Rynnatanmelgyn and Kavtae rivers. Small rodents were recorded on the northern macroslope in the valley of Tergynveem River from its source to the junction with the Kenkereveem River, rarely at the former, but with increasing numbers on approach to the upper border-line of Siberian dwarf pine stands. The crop of the latter was high, and rodents, presumably voles, were very abundant in the dwarf pine stands. Voles were also numerous on the northern bank of Mainits Lake near headstream of the Gytgyveem River, running out of the lake (63°20? N; 176°42? E); the abundance of rodents decreased in the river valley 2-3 km from dwarf pine stands, but they were still common there.
The high abundance of microtine rodents was probably related to the good crop of Siberian dwarf pine. However, we could not verify this hypothesis by visiting the upper reaches of the Vaamochka River on the southern macroslope where there are stands of Siberian dwarf pine and a high crop of pine cones were reported by local people from this area.
