About Sinlahekin Valley (WDFW lands)

Sinlahekin Valley (WDFW lands)
is a rugged landscape with dry ponderosa pine forest, mixed conifer (ponderosa pine and Douglas fir) forest, open shrub-steppe, mixed hardwood (deciduous trees) riparian areas and wetland habitats habitat just south of Loomis, managed by Washington Department of Fish & Wildlife, with 6 photo points monitored year round for forest health.

At the Trailhead

Travel South from the trailhead on Sinlahekin Rd. Photo point #1 is on the right in approx. 1/4 mile. The next five points are close to the road on the right. Photo point #6 is approx. 3 miles from the trailhead.

The Sinlahekin Wildlife Area (SWA) owned and managed by Washington Department of Fish & Wildlife (WDFW) was the first wildlife area in Washington State, established in 1939 with the purchase of 2 parcels at a County tax sale. Most of what is now the SWA was purchased by 1943. An additional 2,833 acres of Federal lands, within and contiguous to WDFW owned lands, under Bureau of Land Management (BLM) administration was withdrawn by Executive Order of President Roosevelt in 1941 and set aside to be managed by the WDFW as part of the Sinlahekin Wildlife Area. Today the SWA is consists of over 14,000 acres.

The WDFW is mandated to preserve protect and perpetuate Washington’s fish and wildlife and the habitat they depend on while maximizing wildlife oriented recreational opportunities. To quote from the old sign at the entrance to the Sinlahekin headquarters road, "This area (Sinlahekin Wildlife Area) was acquired primarily as winter range for mule deer. Its multipurpose acreage also ensures permanent populations of grouse and pheasants. The project provides lasting and diversified benefits to hunters, fishermen, campers and tourists. Purchased by the Department of Game (now Department of Fish and Wildlife) on behalf of the sportsmen of Washington. The Sinlahekin is available to all who wish to enjoy outdoor recreation."

The SWA is one of many state wildlife areas upon which the WDFW manages multiple resources and uses, including timber; forage; recreation; fish and wildlife habitat; archaeological, paleontological, and historical sites. On the SWA there are 10 priority habitat types, 540+ species of vascular plants including 9 threatened or rare species, 43 mammal species, 173 bird species, 86 butterflies species including 1 state candidate species, 13 herptile (reptile & amphibian) species, 16 fish species, 20+ aquatic and terrestrial mollusk species including 1 federal candidate specie, 75 spider species including 5 new state records.

Most of the SWA is dry forest habitat that historically was subjected to and characterized by frequent fires. That is to say fire free intervals were short in duration resulting in very light fuel accumulation with resultant fires tending to be very mild. Plant communities, comprised of mostly fire dependent plant species, subjected to a frequent fire regime have more open ponderosa pine forest structure with less dense stands of brush. For over 100 years fire has been, for the most part, excluded from the fire dependent habitat on the SWA. In the absence of fire the ponderosa pine forest has increased in density, expanded into what were formerly steppe and shrub-steppe habitats. Other consequences of fire exclusion include: 1) an increase of Douglas fir, which competes with ponderosa pine for sunlight, nutrients and moisture; 2) an increase in stressors to ponderosa pine such as insects and diseases causing increased mortality; 3) a decrease in fire dependent species such as quaking aspen and evergreen Ceanothus; and 3) generally degraded wildlife habitat.

In cooperation with the Bureau of Land Management and the USDA Forest Service – Tonasket Ranger District, the WDFW – Sinlahekin Wildlife Area is undertaking dry forest habitat restoration including fuels reduction using mechanical and hand thinning and reconfiguration with fire regime restoration using prescribed fire. This effort will restore resiliency and sustainability to the fire dependent habitat of the Sinlahekin, reduce the risk of severe wildfire, and improve wildlife habitat. This effort will also create jobs and help the local economy.

"Here at Sinlahekin we're working to restore a healthy, fire-dependent ecosystem dominated by a combination of ponderosa pines and shrub steppe vegetation."
