Trap-related injuries to gray wolves in Minnesota

Gray wolves ( Canis lupus ) captured in traps with toothed jaws offset 1.8 cm incurred fewer injuries than those captured in 3 other types of steel traps. Few wolves seriously damaged canine or carnassial teeth while in traps.

Can relocated wolves survive?

Considerable interest has been expressed recently in establishing gray wolves ( Canis lupus ) into parts of their former range (Bailey 1978, Weaver 1978, Klinghammer 1979, Mech 1979, Henshaw 1982). However, the proper procedure for reintroductions is debatable (Klinghammer 1979). To date, wolf relocations have been conducted in Alaska, where 5 2-year-old captive-reared wolves were released into an area occupied by wolves, (Henshaw and Stephenson 1974, Henshaw et al. 1979) and in Michigan, where a pack 4 wolves was released in a relatively wolf-free area (Weise et al. 1975). Wolf reintroductions are expensive, controversial, and attract considerable public attention. The potential for success of an effort will greatly influence the willingness of agencies to attempt reintroductions. The 9 wolves released in Alaska and Michigan had a high rate of mortality, with humans being the major cause. The present study assessed the survival and behavior of relocated wolves. We hypothesized that relocated wolves, especially pups, would have poorer survival when moved outside a familiar territory.
