Located 2.5 miles south of Loomis, the BLM lands in the Sinlahekin Valley consist of approximately 2,834 acres. The BLM lands are adjacent to the 14,314 acre Sinlahekin Wildlife Area.
The Sinlahekin Valley, is a deep, glaciated valley with sheer rock sidewalls rising from the valley floor at about 1,100’ elevation to over 4,000’ elevation. The valley ranges from about one-half to one mile wide and is oriented north-south.
The BLM lands are within both the Sinlahekin Creek and the Coulee Creek watersheds. Sinlahekin Creek is the major flowing water body, while Coulee Creek goes underground most of the year. Dominant habitat types are shrub steppe (bluebunch wheatgrass, big sage, bitterbrush, serviceberry), wetland (hawthorn, water birch, mountain alder, grass/sedges), and dry forest (ponderosa pine, Douglas fir).
The Sinlahekin area has more than 510 vascular plant species (including nine rare species), more than 215 species of birds, 60 species of mammals, approximately 20 species of reptiles and amphibians, more than 25 species of fish, and more than 90 species of butterflies. Mule deer, bighorn sheep, moose, black bear, cougar, waterfowl, wild turkey, forest grouse and rainbow trout and many neo-tropical birds contribute to the popularity of hunting, fishing, camping, and wildlife viewing.
Nearly 100 years of fire exclusion have brought change to the landscape and it is not necessarily beneficial to wildlife. Plans for the drysite forests of the Sinlahekin area include fuels reduction activities such as thinning and logging followed by prescribed burning to try to restore fire and its very important effects that create and maintain wildlife habitat. Photo points have been set up to monitor the changes in the drysite forest structure and response of plants and plant communities to the prescribed burning.

We're working to restore a healthy, fire-dependent ecosystem dominated by a combination of ponderosa pines and shrub steppe vegetation.
