BOISE, Idaho (AP) -- State officials say hunters have reached their limit for killing wolves in a hunting zone in northern Idaho. The Idaho Department of Fish and Game on Tuesday closed the Dworshak-Elk City zone after hunters reached the quota of 18 wolves for the area. It's the third zone where the department has put an end to wolf hunting for the season after hunters reached established bag limits. Overall, the officials report hunters have killed 106 wolves across all 12 statewide hunting zones. The state set a hunting quota of 220 wolves for the season, which began earlier this year and ends next month. Other zones closed are in the Upper Salmon and the McCall-Weiser area.
