Surveys were conducted hySES biologists in the summer/fall of 1998 to obtain these required data, The rnuo|m of these surveys are provided below in Section 3.2. A significant decline of the Sxhum|on oonubimy oubpnpo|mion has been documented in the FVVS files from 1891 to 1396. The primary oou4o for this population decline was reported to be habitat degradation from lack of fire o, mechanical management actions [ro|and 1996).
