A total of 94 brown bears, five black bears and five wolves were killed in the program that began May 10 and ended June 4, the Alaska Department of Fish and Game said this week. That’s more than four times the number biologists predicted would be taken. State biologists also say disease and changing food supplies might be a bigger factor overall.

The Mulchatna herd was not at the peak numbers it once had decades ago. Over-hunting, migration changes and wolf predation could be leading causes of decline in herd.

Researchers in southwestern Alaska are investigating why the once-thriving Mulchatna caribou herd has not rebounded, focusing on factors such as disease and nutrition. The study employs real-time monitoring of pregnant caribou and detailed fat measurements to evaluate calf survival and overall herd health.

Researchers in southwestern Alaska are closely monitoring the Mulchatna caribou herd using advanced technology to determine whether disease or nutrition is behind the herd’s failure to recover. The study comes amid efforts to understand a dramatic population decline that has led to a subsistence hunting closure.
