Black Hills Timber Sustainability General Technical Report (GTR-422)

On March 23, 2021 the USDA Forest Service's Rocky Mountain Research Station published the general technical report, A Scenario-Based Assessment to Inform Sustainable Ponderosa Pine Timber Harvest on the Black Hills National Forest. The report, based on forest census data, provides context, rationale, and evaluation of harvest level scenarios across a range of mortality, growth rates, and time periods in the Black Hills. This report offers scientific information that can inform discussions concerning future harvest levels on the Black Hills National Forest. 

To ensure the highest quality data and scientific standards, a comprehensive review process was used. Scientists, technical and blind peer reviews and an open public comment period for a draft report produced over 350 comments. In response to reviewer comments, the final report contains ten times the original number of possible future scenarios covering a wide range of mortality, growth, and harvest rates over 5, 20, and 80 year harvest periods. Additionally, the draft report was expanded and revised to include data descriptions that included information on how gross growth, net growth, and net change are calculated; an appendix to describe land area and determination of suitable land for timber production on the Black Hills National Forest; and clarifications on assumptions and terms like sustainable forest management, sustainable forestry, and sustained yield.

A Scenario-Based Assessment to Inform Sustainable Ponderosa Pine Timber Harvest on the Black Hills National Forest is a scientific document that uses rigorous data obtained during a Black Hills National Forest census. The primary finding of the report is that the current volume of standing live sawtimber does not support a long-term sustainable sawtimber supply at current harvest levels, under a wide range of scenarios considering growth and mortality rates. The report suggests harvest levels need to be adjusted to allow sawtimber volume recovery and create long-term sustainability. The report is not a policy or decision document. The data, general technical report, and other best available science are available for consideration during forest management decisions.
