Annual wolf report available from IDFG

By Ed Mitchell, IDFG

    The 2009 annual summary of wolf recovery in Idaho is now available, and it shows wolf numbers are nearly the same as 2008.

   The Idaho 2009 Wolf Conservation and Management Progress Report includes the current status of the wolf population in Idaho. Biologists documented 94 Idaho resident and border wolf packs at the end of 2009. The minimum population was estimated at 843 wolves. In 2008, the minimum population estimate was 856 wolves.

   In addition, 20 documented border packs were counted for Montana, Wyoming and Washington that established territories overlapping the Idaho state boundary and likely spent some time in Idaho.

   Of the 65 packs known to have reproduced, 49 packs qualified as breeding pairs by the end of the year. These 65 reproductive packs produced a minimum of 204 pups.

   In Idaho, wolf packs ranged from the Canadian border south to Interstate 84, and from the Washington and Oregon borders east to the Montana and Wyoming borders. Dispersing wolves were occasionally reported in previously unoccupied areas.

   Sixteen previously unknown packs were documented during 2009, but the overall net increase was only six documented packs in the state. During 2009, 343 wolf observations were reported on Fish and Game's Web site report form.

   Biologists confirmed the deaths of 275 wolves in Idaho during 2009; three of those belonged to Montana packs and were addressed in that state's report. Of known wolf mortalities, hunter harvest accounted for 135 deaths and agency control and legal landowner take in response to wolf-livestock depredation accounted for 94 deaths.

   Twenty wolf mortalities were attributed to other human causes, including illegal take. The cause of 24 wolf mortalities could not be determined and were listed as unknown, and two wolves died of natural causes.
