No Action Alternative (Alt. B): Under this alternative 0.7 miles of motorized routes
occur within the 3 occupied areas, and 2.8 miles within designated southwestern willow
flycatcher (SWWF) critical habitat. These routes continue to cause habitat loss, and an
increased potential for nest parasitism. The potential for collision loss or poaching loss is
relatively low. The potential disturbance area in occupied sites (57 acres), and SWWF
critical habitat (176 acres) continues to cause the potential for indirect effects. Knight
and Cole (1991) indicated that birds may respond to human activity by altering their
behavior, spatial distribution, and habitat use. Corridors created by roads can fragment
songbird habitat, and human activity within these areas may displace or disrupt breeding
