d. southeast facing slopes that are used as a sp):'ing migration route. This route is sanewhat constricted at preejent because of terrain, landfoDn, vegetative cover and snowmelt cparacteristics. 2) The back bcMI developnent would occur within la calving area which is a habitat of limited extent. 3) tlle back bcMI developnent is within a larger area of habitat c~nsidered to be prime rearing and sUlllller habitat for deer and espeoially elk. I COnsequently, ski area development in the back b~l area would be much more disturbing to, at least, deer and el~ than could be SUDnised fran the few acres of actual habitat I that would be altered. I i Same wildlife 'species with greater mobility and flexibility would be displaced or forced into other habitats. I Many of these habitats may be either partially or fully occupi~. If a certain species habitat is limited in extent it may verY well be fully occupied and unable to accormoodate additional animals. In these situations, these animals may eventually bel lost to the population. In other situations there may be a~jacent habitats that are not fully occupied and the aniInals forced into these habitats will be able to survivel however, this $y be at a lower level of productivity because of stress factors \;>rought about by moving and/or residing in habitats that would be lutilized to full capacity. Many of the nongame birds and maImlalsl will eventually move back into habitats they previously occupied,1 and sane of the large species may eventually partially utilize! previously used habitats. However, this use would be very limitec!l in extent. Elk will be the species most affected by displacement with deer also being affected, but to a lesser extent. I I I Alternativ~ ~ I I This alternative has nearly the same habitat ca~bility potential as Alternative TWo, and receives only 99 fewer lacres of habitat disturbance than does Alternative TWo. 3.0 m~les of road per . section would be constructed. The utilization of calving and fawning habitat w~uld be altered in areas A and C (Map 20). Area E would not be aa heavily impacted as in Alternative TWo since there would not be a'ny actual habJ.tat disturbance and there would be less activity ~d harassment than from Alternative TWo. I Spring migration in area F (Map 20) would not bel directly affected by ski area deve10pnentl however, there could be more animals utilizing route F, depending upon what reactiorj the animals have to disturbances and harassment in areas B and D!, Map 20. If IlIOre animals were to use route F in the spring mig~ation, then there would be IlIOre animals utilizing calving area E. 206
