The U.S. Forest Service recently issued its 2017 Forest Health Survey for the Black Hills National Forest, reports KOTA News. Aerial surveys indicated that approximately 2,900 acres were impacted by mountain pine beetles last year—a slight uptick from 2,500 in 2016. However, as the species is native to the region some trees will continue to perish each year which is a natural process for the region.
Forest Service officials found it difficult to locate pine beedle brood at their five survey locations. The officials credited management practices such as thinning and sanitation with the reduction in mountain pine beetles.
