WOLF PREDATION ON SHEEP IN ALASKA
By T.R. Mader, Research Director


These pictures were taken by an Alaska Fish and Game Department biologist following a kill of 20 healthy rams by 5 wolves in November, 1988.

LOCATION: Wrangell St. Elias National Park/Preserve in Game Management Unit 11 between the Dadina and Chestasline Rivers.

NUMBER OF DEAD RAMS: 20
12 rams - little or no use by wolves
6 rams - 40 to 90% consumed by wolves
2 rams - No estimate of consumption. Checked too late- damaged by ravens.

BONE MARROW: All samples checked showed high fat levels. Animals not nutritionally stressed. All animals checked appeared in good physical condition with no defects making them susceptible to predation.

SHEEP AGES: 2-9 years old
SNOW DEPTH: 14" - 29"

Several of the kills were accomplished by severing the wind pipes and jugular veins without other damage.
