Powerline Corridors as Possible Barriers to the Movements of Small Mammals

Displacement experiments were used to determine the effect of two widths of powerline rights-of-way as potential barriers to movements of Blarina brevicauda and Peromyscus leucopus. Both species returned to home areas from release sites across the right-of-way. On the average, the shrews took longer to return and were somewhat less successful than the mice.
