Two areas together comprise the Williams Lake Community Forest. Selected from the area that overlaps the Secwepemc traditional territory and Central Cariboo Forest District, these areas were identified as being capable of sustaining a long-term forestry enterprise. Tree species and stand age profiles and compatibility with other tenure and land-claim processes are among the many considerations put into area selection.

The NeSextsine (Flat Rock) Block  (5927 hectares) overlooks the Fraser River, is just west of Williams Lake, B.C., and is situated in the Interior Douglas-fir biogeoclimatic zone. The forest growing in the very dry climate there is made up of multi-aged Douglas-fir and provides important mule deer winter habitat. The Peskwenkwinem (Potato Mountain) Block (22 912 hectares) spans an area between the Likely and Horsefly Roads from Potato Mountain eastward and to Beaver Valley in the north. The climate of the Sub-Boreal Spruce biogeoclimatic zone leads to productive forests with numerous tree species and age classes in this area.
