Soup Grizzly Bear Subunits. 

 Presently there are 1,113 acres 



(9.1 percent) of denning, 5,194 

 acres (42.4 percent) of mature 

 forage, 573 acres (4.7 percent) 

 of young forage, 4,254 acres 



(34.7 percent) of travel, and 

 1,131 acres (9.2 percent) of 

 temporarily unavailable habitat. 



Direct Effects to Canada Lynx

 Alternative to Canada l/ynx 



No additional activities would 

 occur; therefore, no direct 

 effects would be expected. 



• Direct Efffects qfthe Action Alternative to 

 Canada L/yna: 



Some disturbance of Canada lynx 

 could occur in areas with 

 adequate cover for lynx to 

 travel through. However, lynx 

 appear to be relatively 

 tolerant of human presence and 

 road use {Mo-wat 2000] -, 

 therefore, no substantial 

 direct effects would be 

 expected. A slight potential 

 increase for mortality due to 

 road traffic on gated and/or 

 new roads would be possible, 

 though the risk of this 

 occurring would be extremely 

 small. Lynx do not appear to 

 avoid roads at low traffic 

 volumes (i?uedigrer 2000) , so 

 increased logging traffic on 

 open and gated roads is not 

 expected to displace or 

 increase the energetic cost of 

 individual lynx. The area is 

 not likely to be used by lynx 

 and lynx tend to be tolerant of 

 human disturbance; therefore, 

 negligible effects to Canada 

 lynx are expected under the 

 action alternative. 



Indirect Effects to Canada Lynx 



• Indirect ^ffecttt qfthe JVo-Action 

 Mtemative to Canada L/jfnx 



Canada lynx habitat in the 

 project area would be retained. 



Retention of jackstrawed piles 

 of blown-down trees could offer 

 additional foraging and denning 

 habitat structure. However, 

 these areas are lower and drier 

 than habitats typically used by 

 lynx, so the benefits of this 

 retention are expected to be 

 extremely small . 



• Indirect Effects ofttie Action Alternative 

 to Canada l/ynac 



Under this alternative, 

 salvaging of dead, down, and 

 dying timber would occur on 66 

 acres of mature lynx foraging 

 habitat and 196 acres of 

 general habitat. The proposed 

 harvesting would not alter the 

 availability of lynx habitat, 

 but could reduce prey density 

 by removing downed wood. 

 Additionally, approximately 12 

 acres of young foraging habitat 

 and 14 acres of other suitable 

 habitat would undergo 

 reductions of ladder fuels 

 aimed at reducing fire hazards 

 around private lands . These 

 treatments are expected to 

 reduce prey densities to some 

 degree. The reductions are not 

 expected to affect Canada lynx 

 appreciably because these 

 changes would occur in marginal 

 habitats that are lower in 

 elevation and drier than those 

 typically used by lynx. 



Cumulative Effects to Canada Lynx 



• Cumulative Effect* of the J\o-Action 

 Alternative to Canada I/ynx 



No Canada lynx habitat would be 

 modified. Forage availability 

 would likely increase over the 

 short term due to the added 

 habitat structure provided by 

 the pockets of blown-down 

 timber. No additional 

 reductions in quality or 

 quantity would occur in the 

 subunit .
