Can relocated wolves survive?
Steven H. Fritts, William J. Paul, L. David Mech
1985, Wildlife Society Bulletin (13) 459-463
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...
