Masked shrew (Sorex cinereus Kerr) populations in upland hardwood forests of Upper Michigan were studied to determine their breeding status during the dry year of 1976. These populations lacked pregnant adult females and the younger age classes of juveniles. Other age/sex groups were well represented when conditions were moist. Apparently, masked shrews do not breed in upland hardwoods during dry conditions and may entirely abandon uplands during excessively dry periods.
