The U.S. Forest Service published new information on the history of pine beetles in the Black Hills this week, as reported in a press release by the agency and KOTA TV News. The agency also offered presentations of the report this week at the Mystic Ranger District Office and the Black Hills Experimental Forest.
The report highlights the history of pine beetles, going back to 1902 when they were first described until 1985, when significant studies were conducted on the species. Forest Researcher Russell T. Graham noted that beetles fall subject to inbreeding which causes their populations to become unhealthy. As a result, the population declines.
