Least chipmunks preferred the right-of-way ([chi square] = 11.
An adult male southern red-backed vole crossed the right-of-way at powerline site 2 during its natural movements (two crosses by one individual).
During their natural movements, North American deermice readily crossed the right-of-way (13 crosses by nine individuals) and the right-of-way at control sites (four crosses by four individuals).
Least chipmunks crossed the right-of-way in their natural movements (four crosses by three individuals) and after translocation at powerline sites.
Southern red-backed voles in edge and forested habitats at powerline sites exhibited significant directional movements parallel to the right-of-way (Rayleigh's test, P < 0.
Our results differ from Goldingay and Whelan (1997), who reported that abundance decreased along a powerline right-of-way in eucalyptus forests.
The open, early-successional habitats created by the powerline right-of-way likely favors increased abundance of least chipmunks and North American deermice.
Although rate of capture may have increased in forested habitat due to greater distance from the right-of-way, the higher rate of capture in forested habitat at control sites suggests that availability of water also was a factor.
Although presence of riparian habitats may have influenced our results, we suggest that the right-of-way also had an effect on distribution and density of southern red-backed voles.
We do not believe our data support avoidance of the right-of-way by cinereus shrews.
Least chipmunks were significantly more abundant within the right-of-way at powerline sites.
The influence a right-of-way has on movements often depends on successional stage of the right-of-way, with early succession being a barrier to forest-dwelling species (Gates, 1991).
