Continental-scale tree-ring-based projection of Douglas-fir growth: Testing the limits of space-for-time substitution

Publications Posted on: July 02, 2020
A central challenge in global change research is the projection of the future behavior of a system based upon past observations. Tree-ring data have been used increasingly over the last decade to project tree growth and forest ecosystem vulnerability under future climate conditions. But how can the response of tree growth to past climate variation predict the future, when the future does not look like the past?

The impact of climate change on America's forests

Publications Posted on: August 01, 2018
This report documents trends and impacts of climate change on America's forests as required by the Renewable Resources Planning Act of 1974. Recent research on the impact of climate and elevated atmospheric carbon dioxide on plant productivity is synthesized. Modeling analyses explore the potential impact of climate changes on forests, wood products, and carbon in the United States.

Development of a forest biochar spreader

Science Spotlights Posted on: August 25, 2016
Rocky Mountain Research Station scientists and their partners with the U.S. Forest Service Missoula Technology and Development Center, Washington State University, and John Jump Trucking, Inc., developed and tested a high-capacity biochar spreader to reduce the cost and facilitate the application of biochar as a soil amendment.

Western larch spacing study: Over 60 years of growth

Projects Posted on: August 24, 2016
Researchers are using existing long-term studies to answer questions about overstory and understory carbon accumulation in western larch forests.Four western larch stands were remeasured in the summer of 2015. Stand growth and carbon sequestration were evaluated by estimating the carbon pools of live trees, understory vegetation, dead woody material, and the forest floor (decomposing plant material).

Monitoring trends in ecosystem productivity: Identifying drivers and indices of change

Projects Posted on: August 17, 2016
Climate is a major driver of spatial and temporal patterns in primary productivity. Relating trends in ecosystem productivity to climate across the United States will enhance our understanding of how climate change will influence ecosystem productivity in the future and support climate change adaptation and mitigation activities.

Total belowground carbon flux in subalpine forests is related to leaf area index, soil nitrogen, and tree height

Publications Posted on: August 10, 2016
In forests, total belowground carbon (C) flux (TBCF) is a large component of the C budget and represents a critical pathway for delivery of plant C to soil. Reducing uncertainty around regional estimates of forest C cycling may be aided by incorporating knowledge of controls over soil respiration and TBCF.

Data for National Fire and Fire Surrogate study: environmental effects of alternative fuel reduction treatments

Datasets Posted on: June 08, 2016
Comprised of 12 sites nationwide, the Fire and Fire Surrogates study (FFS) is a comprehensive interdisciplinary experiment designed to evaluate the economics and ecological consequences of alternative fuel reduction treatments in seasonally dry forests of the United States.

Carbon sequestration in wood and paper products

Publications Posted on: May 12, 2016
Recognition that increasing levels of CO2 in the atmosphere will affect the global climate has spurred research into reduction global carbon emissions and increasing carbon sequestration. The main nonhuman sources of atmospheric CO2 are animal respiration and decay of biomass. However, increases in atmospheric levels are attributed mainly to fossil fuel burning and land use change.

Below-ground process responses to elevated CO2 and temperature: a discussion of observations, measurement methods, and models

Publications Posted on: May 12, 2016
Rising atmospheric CO2 and temperatures are probably altering ecosystem carbon cycling, causing both positive and negative feedbacks to climate. Below-ground processes play a key role in the global carbon (C) cycle because they regulate storage of large quantities of C, and are potentially very sensitive to direct and indirect effects of elevated CO2 and temperature.

Visualizing carbon storage of harvested and burned forests

Projects Posted on: February 08, 2016
Forest management and natural disturbance can have a significant impact on storage or emission of greenhouse gases. Researchers with the Rocky Mountain Research Station designed the Forest Carbon Management Framework (ForCaMF) to model how harvested and burned stands contribute to overall carbon storage over different time scales. ForCaMF was used to conduct analyses across all 76 million ha of National Forest System land by Forest Service Region. Through informed forest management, additional forest carbon storage is achievable.
