A new report by USDA Forest Service researchers provides science-based information to help decision-makers, practitioners, and researchers to promote the sustainable harvest of non-timber forest products. The Assessment of Non-timber Forest Products in the United States under Changing Conditions synthesizes the best available science for managing non-timber forest resources in the U.S.

Many private landowners harvest non-timber products to generate income from their forests,” said Forest Service Interim Chief Vicki Christiansen. “The harvest of specialty products like medicinal herbs, wild onions, and mushrooms creates jobs, boosts rural economies, and meets growing market demands.”

Economic Risks 

Commercial markets for many raw non-timber forest products are well-established, even when not highly visible

These harvests contribute millions of dollars to the U.S. economy each year. For example, in 2001 the estimated market value of four medicinal and floral species (bloodroot, black cohosh, American ginseng, and galax) exceeded $25 million. However, the lack of available data has impeded a thorough economic analysis of these and other non-timber products. The Forest Service report helps fill this gap and guides, readers, through the laws and regulations at the local, state, and federal levels that complicate sustainable management and conservation of these important natural resources.

Commercial markets for many raw non-timber forest products are well-established, even when not highly visible,” said Toral Patel-Weynand, national director of Sustainable Forest Management Research and one of the report editors. “However, changing conditions from environmental stresses like drought, fire, insects, and disease, and climate variability put all of these economic benefits at risk.”

Importance of non-timber products

Non-timber forest products are harvested in all types of forest, grassland, and wetland environments. Changes in forest dynamics, including soil moisture and temperature, may impact populations and ranges of non-timber forest species, particularly understory spring ephemeral herbs. The report assesses the potential effects of climatic variability on non-timber forest products and how those effects may disrupt the benefits derived from non-timber forest products.

The report also highlights the importance of non-timber forest products to the cultures of diverse communities in the U.S. Including these stakeholders in management and policy dialogues will help promote the sustainable harvest of non-timber forest products for decades to come. The mission of the Forest Service, an agency of the U.S. Department of Agriculture, is to sustain the health, diversity, and productivity of the nation’s forests and grasslands to meet the needs of present and future generations.
