Beaver 1967 Aptera study 73 10 July 1350 Beach Ridge near Micromet sample area. D. Pitelka and I left for Beach Ridge sampling area. We set up a transit running from S70 N ~ NE direction from the lower level of the south slope of Beach Ridge to the high polygons of the ridge. A second line was run from starting point of the previous line to a point S.W. of other line. [Diagram showing two intersecting lines labeled "line # I" and "line # II"] Five foot blocks, 18 wide were set up by placing a mile along the string, and extending an 18" static perpendicular to the string. All tubules in this area were counted and saved. Habitat was noted as to sampling progressed. 42 five foot sections were sampled on line #I and 20 on line #2. Next time, I'll put in detailed microhabitat data. Also, the data will be put in metric units to give a 1/2 m^2 sample at each station. The data for the first run of line #I & II are on the following pages. See journal for situation. On line II, we found 3 tubules that appear to be different. Two were mating. These are combined with #10.
