The National Elk Refuge in Jackson, Wyoming, has released its latest biological update, detailing movements of elk, counts of various ungulates, and the outcomes of a five-year program aimed at reducing reliance on supplemental feeding.
Elk Movements and Ungulate Counts:
Following the closure of the elk hunting season on December 13, 2024, there was a significant migration of elk to the southern part of the Refuge. Weekly counts in this area show a stark contrast:
- December 13, 2024: No elk were observed, but counts included 3 pronghorns and 28 bighorn sheep.
- December 19, 2024: The area saw an increase to 3,080 elk, with 53 bighorn sheep noted.
No bison, deer, or moose were observed during these counts.
Feeding Reduction Step Down Plan:
The Refuge has been implementing the “Step-Down Plan for Bison and Elk Management” for the past five winters, with the goal of reducing both the number of elk wintering on the Refuge and the reliance on supplemental feeding. Here are the key outcomes:
- The plan reduced the average length of the feeding season by 8 days, cutting elk fed days by 15%.
- Despite these efforts, there was no significant change in the average number of elk wintering on the Refuge.
- Higher elk calf mortality was observed, primarily due to severe winter conditions.
- The plan’s effectiveness was challenged by deep snow and late snowmelt, which influenced the decision to extend feeding periods to prevent elk from moving to private lands.
The report suggests that alternative strategies might need to be explored in future updates to the Bison and Elk Management Plan to meet the objectives of reducing elk numbers, decreasing supplemental feeding, and managing Chronic Wasting Disease.
