In 2008 the WSF took over a number of projects from local tourism buisiness. Among these were a sheep study dating back to 1991, where the population of Bighorn Sheep has been surveyed in both Shulaps Mountain Range and Big Creek/Relay area. The purpose is to get accurate population numbers for each group, of rams, ewes and lambs, as well as yearly lamb survival, migration patterns, winter ranges, summer ranges and predator impact. Aerial surveys are periodic and ongoing in this area.
