WCT Multi-state Assessment February 1 0. 2003 



affected a portion of the population. Participants varied in how they rated whether a 

 conservation population was impacted by a particular activity, especially for conservation 

 populations that occupied relatively large areas of connected habitat and a particular activity was 

 occurring only on a portion of the occupied habitat. For these types of conservation populations 

 and activities some participants ranked impacts as none, some as possible, and some as known. 



Table 8. Codes and descriptions for management activities that could potentially impact 



designated conservation populations of westslope cutthroat trout assessed in 2002. 



Summaries from Database 



Data provided by the fishery professionals were summarized directly from the Microsoft Access 

 database using queries within Access. Summarized data were then copied to Excel spreadsheets 

 where these data were further reduced to produce summary tables and figures. Most summaries 

 within this report are summarized over the entire historical range of WCT. A few populations 

 that inhabited waters outside the historical range were included in separate analyses. Additional 

 summaries by 4^*^ code HUC are provided in appendices. 



Summaries that Linked Database to GIS Layers 



To better assess existing regulatory mechanisms associated with land management for the 

 streams currently occupied by WCT we used Arcview to select ("clip" feature in Arcview) 

 stream segments occupied by WCT that were within designated Forest Service wilderness areas, 

 designated Forest Service "roadless" areas, USD! National Parks, all federally managed lands, 

 and those Forest Service and BLM lands within the Upper Columbia River basin where fNFISH 

 (U.S. Department of Agriculture and U.S. Department of the Interior 1995a) and PACFISH (U.S. 

 Department of Agriculture and U.S. Department of the Interior 1995b) restrictions are in place. 

 After clipping the stream segments occupied by WCT using the above polygon layers we 

 computed the length of streams occupied by WCT that were within the above land management 

 designations using a query in Arcview ("[Shape]. retumlength" query).
