December 18, 2025 windstorm:
-
Many areas in the Black Hills experienced wind damage from the December 18 storm. Trees were uprooted or snapped causing significant damage. Now that cleanup is underway, it is important to note that the downed trees and limbs can be an attractant to the pine engraver beetle. The beetles use green slash to survive and although the beetles are not active this time of year, the downed woody material can remain green throughout the winter and spring. So when they emerge next April/May, we may see a boom in their numbers. Dr. John Ball, SDSU Forest Health Specialist, recently published an article in the Tree Pest Alert about the windstorm and the potential pine engraver beetle outbreak. He offers advice on how to best handle the downed debris to avoid/minimize any beetle issues. Options include: lop and scatter slash, chip or masticate slash, and cut logs into 2-foot lengths – all options hasten wood dry out. Also, avoid piling brush into small piles (6-8 feet in size). Small piles can attract beetles when they emerge in the spring.
-
Note: if you plan on thinning your property, it is recommended that you avoid thinning between Mid-April and September when beetles are active.

Cost-share funding opportunity: the USDA Farm Service Agency (FSA) has approved Emergency Forest Restoration Assistance for Custer, Fall River, Lawrence, and Pennington counties. Cost-share funds are to address damages from the severe wind storm that occurred December 18, 2025. If approved, cost-share can be used for debris removal (including hazard tree removal), woody residue treatment, and fence repair/replacement. Interested landowners in Custer county should contact the FSA office in Hot Springs (745-5716, ext. 2) for additional information and for an application.
