Insect Sampling
10 June Barrow, Alaska
Several samples have been taken during the
past few days, but only occasional larvae have
been found.
Today a plot was semi-established
on The ridge - N. 1 VDTA's Area (No. 1 Trophonia
[illegible] A+B). The ridge is grassy with slight
polygons. Two m² plots were placed
on polygons (Btc) + one in a trough (A).
A soil sample was taken 2' away for A+
B. The results of exploring there:
A: 1 - ½ sq' - 3 chironomids - 0.4/sqft or 376/sq.yd.
B -
All plots were watched for 10 min. 3 spiders
were seen in plot A; nothing in the other two. This
obs. method will only be good for fairly
energetic & certain not limning activity.
