Carbon storage and carbon-to-organic matter relationships of three forested ecosystems of the Rocky Mountains

Publications Posted on: May 11, 2018
Fluctuations in atmospheric carbon dioxide is influenced by carbon storage and cycling in terrestrial forest ecosystems. Currently, only gross estimates are available for carbon content of these ecosystems and reliable estimates are lacking for Rocky Mountain forests.

Long-term effects of fuel treatments on aboveground biomass accumulation in ponderosa pine forests of the northern Rocky Mountains

Publications Posted on: July 19, 2017
Fuel treatments in ponderosa pine forests of the northern Rocky Mountains are commonly used to modify fire behavior, but it is unclear how different fuel treatments impact the subsequent production and distribution of aboveground biomass, especially in the long term.

Early forest thinning changes aboveground carbon distribution among pools, but not total amount

Publications Posted on: January 12, 2017
Mounting concerns about global climate change have increased interest in the potential to use common forest management practices, such as forest density management with thinning, in climate change mitigation and adaptation efforts. Long-term effects of forest density management on total aboveground C are not well understood, especially for precommercial thinning (PCT) implemented very early in stand development.

Maintaining long-term productivity of Inland Northwest forests after bioenergy harvesting

Science Spotlights Posted on: August 25, 2016
Research at the Coram Experimental Forest points to resilient western larch forests in the cool-moist climatic regime that can fully recover carbon and nutrients before the next harvest rotation. Scientists used a site that had been harvested by cable logging and broadcast burning in 1974 to evaluate long-term impacts and recovery. Shrub diversity and biomass were the same or greater than pre-harvest samples and indicate the shrub community is quite resilient to biomass harvesting.

Long-term effects on distribution of forest biomass following different harvesting levels in the northern Rocky Mountains

Publications Posted on: October 05, 2015
With increasing public demand for more intensive biomass utilization from forests, the concerns over adverse impacts on productivity by nutrient depletion are increasing. We remeasured the 1974 site of the Forest Residues Utilization Research and Development in northwestern Montana to investigate long-term impacts of intensive biomass utilization on aspects of site productivity.

Forest development and carbon dynamics after mountain pine beetle outbreaks

Publications Posted on: June 27, 2014
Mountain pine beetles periodically infest pine forests in western North America, killing many or most overstory pine stems. The surviving secondary stand structure, along with recruited seedlings, will form the future canopy. Thus, even-aged pine stands become multiaged and multistoried.

Mechanisms of carbon storage in mountainous headwater rivers

Publications Posted on: February 06, 2013
Published research emphasizes rapid downstream export of terrestrial carbon from mountainous headwater rivers, but little work focuses on mechanisms that create carbon storage along these rivers, or on the volume of carbon storage. Here we estimate organic carbon stored in diverse valley types of headwater rivers in Rocky Mountain National Park, CO, USA.

Influence of prescribed fire on ecosystem biomass, carbon, and nitrogen in a pinyon juniper woodland

Publications Posted on: September 13, 2010
Increases in pinyon and juniper woodland cover associated with land-use history are suggested to provide offsets for carbon emissions in arid regions. However, the largest pools of carbon in arid landscapes are typically found in soils, and aboveground biomass cannot be considered long-term storage in fire-prone ecosystems. Also, the objectives of carbon storage may conflict with management for other ecosystem services and fuels reduction.

Soil carbon and nitrogen in a Great Basin pinyon-juniper woodland: Influence of vegetation, burning, and time

Publications Posted on: December 03, 2009
Much of the Great Basin, U.S. is currently dominated by sagebrush (Artemisia tridentate ssp. (Rydb.) Boivin) ecosystems. At intermediate elevations, sagebrush ecosystems are increasingly influenced by pinyon (Pinus monophylla Torr. & Frem.) and juniper (Juniperus osteosperma Torr.) expansion.

Forests and carbon storage

Publications Posted on: August 05, 2008
Forests store much carbon and their growth can be a carbon sink if disturbance or harvesting has killed or removed trees or if trees that can now regrow are planted where they did not historically occur. Forests and long-lived wood products currently offset 310 million metric tons of U.S. fossil fuel emissions of carbon--20 percent of the total (Pacala et al. 2007).
