A METHOD FOR DECREASING TRAP MORTALITY OF SOREX

Due to high mortality rates, live trapping Sorex spp. is difficult. In an attempt to reduce mortality we used food supplements in pitfall tr aps. Red worms (Eisenia foetida) did not significantly reduce trap mor tality of Masked Shrews (Sorex cinereus); however, about 7 g of whitef ish per pitfall did significantly reduce trap mortality. This method m ay be useful for studies requiring the live capture of Sorex spp. and when trapping in situations where species of shrews having special con cern may be encountered.
