The largest continuous unit is Scotch Creek�s 8,694 acres, located about 10 miles northwest of Omak and four miles southeast of Conconully. It�s primarily shrub steppe, with some conifer forest and riparian habitat, and 80 acres maintained in agriculture (sharecrop fields). To date, nearly all of the 1,500 acres of old dryland agricultural fields have been restored to native shrub steppe habitat, providing diversity and nesting cover for sharp-tailed grouse. Over 100,000 trees and shrubs have also been planted in wet draws, north slopes, and under irrigation to provide critical winter habitat for sharp-tailed grouse. In recent years between 30 and 40 sharp-tailed grouse have wintered in the water birch plantings near the area headquarters. Scotch Creek, a spring fed stream originating about three miles west of the area boundary, submerges into a marsh area at the eastern boundary. There are no inlets, outlets or tributaries to this 10-mile long perennial stream. Several springs and two lakes are also located on the property. This unit is a major recreation area for both fishing in the summer and deer hunting in the fall.
