Timber Sustainability on the Black Hills National Forest
The Black Hills National Forest produced the agency’s first federal timber sale in 1899. This timber sale is referred to as Case Number One. During the past 120 years, the Forest Service and the timber industry have built a strong partnership in management of the forest. Throughout the first 60 years, timber harvest levels fluctuated between 30,000 to 50,000 CCF (hundred cubic feet) on the 1.2 million-acre forest. Since then, annual harvest levels have fluctuated between 100,000 to 250,000 CCF, making the Black Hills National Forest one of the agency’s highest timber producing forests in the country. In order to effectively manage the forest, the agency has collected and analyzed data regarding timber growth and harvest on the Black Hills for decades. The predominant tree species in the Black Hills is Ponderosa Pine.
The landscape in the Black Hills has changed significantly over the past 20 years due to large wildfire impacts, a 20-year Mountain Pine Beetle (MPB) epidemic and high annual timber harvest levels to minimize impacts of the MPB. In recognition of the changed condition, the USDA Forest Service entered into a collaborative agreement with stakeholders from the timber industry and Wyoming and South Dakota State Foresters to quantify the level of change. That agreement resulted in a forest-wide intensified data collection effort, which focused on ponderosa pine, by the USDA Forest Service Research and Development Forest Inventory and Analysis (FIA) team. To collect the data, field work was conducted during 2017 to 2019 with final results and analysis shared with stakeholders and the public in early 2020.
The Black Hills National Forest, Rocky Mountain Research Station and the Forest Inventory and Analysis staff have worked extensively with stakeholders to share, scrutinize, and discuss the data and analysis of timber sustainability into the future. Through a transparent process, the Forest Service is involved in a rigorous dialogue with all stakeholders about what the data reveals about the condition of the forest in order to inform our decisions about the future of the commercial timber program. The Forest Service is committed and obligated to rely on the best available science to inform timber program decisions.
The Black Hills National Forest is committed to the continued success of our timber industry partners. The data collected over the past several years is among the considerations that will help the agency to determine adjustments to harvest levels to match the ecological capacity in a way that also provides continued long-term support of the timber industry. Collaboration with partners, stakeholders and local government officials will continue to ensure an economically viable, sustainable program is developed for future generations. The Black Hills National Forest is proud of its 120-year partnership with the timber industry.
