Figure 1—Map of study area in Oregon Cascade Range and central Oregon. Small squares are townships, about 10 kilometers square. Circles are sample locations to nearest quarter of a township. Solid circles represent two families per location; hollow circles represent one. Township numbers (3 N. through 41 S.) are on the left margin; range numbers (3 E. to 27 E.) are given on the horizontal lines. Areas outlined with fine lines are current seed zones (Tree Seed Zone Map 1973). Larger areas with heavier outlines are proposed new zones. Other geographic landmarks are the Cascade crest (dashed line), the towns of Hood River (HR), The Dalles (TD), Madras (M), Prineville (P), Bend (B), Klamath Falls (KF), and Lakeview (L) and Crater Lake (CL), Silver Lake (SL), Klamath Lake (KL), and Goose Lake (GL)..
