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.
