Richardson 1937 1 mi. S Foot Lake, Paulina Mts., Deschutes Co., Oregon June 13, 1937 - The region studied in is between 6,000- 7,000', the lower country having some yellow Pine, Lodge Pole Pine becoming dominant higher up, with fairly large extents of Hemlock seemingly on high North slopes. Surface water and vegetation are almost entirely lacking, save for sparse grass clumps in some places and a little manzanita (Arctostaphylos). This seems due entirely to the porous nature of the junice ground and the very little thick- ess (c 3") of humus or soil. Foot Lake (or Paulina Lake) being an isolated body of water in this whole mountain region might show interesting relations to birds or other animals. Foot Lake was only cursory-ily seen. A Barrow's Golden-eye was seen in it, and robins were seen around the shore. A deafening chorus of Wyla was heard at night - evidence of their concentration around the lake. Whether one considers food, soil or veg- etation the primary factor in bird presence or abundance, it seems equally clear that they combine in this region - little soil giving little vegetation giving little plant or insect food, giving a scarcity of birds.
