Pollinators of the Great Plains: Disturbances, stressors, management, and research needs

Science Spotlights Posted on: March 24, 2021
Pollinators are declining in the Great Plains of North America. Reduced or degraded grasslands produce fewer flowers, which pollinators need. Pollinator management can provide resources to help pollinators withstand a variety of interacting stressors and concurrently support functioning rangeland ecosystems.

Scenario-Based Assessment Helps Inform Sustainability of the Black Hills National Forest

FS News Posted on: March 23, 2021
FORT COLLINS, Colo., March 23, 2021 – USDA Forest Service's Rocky Mountain Research Station scientists today 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 and growth rates in the Black Hills. This report offers scientific information that can inform discussions concerning future harvest levels on the Black Hills National Forest.

Sustainable timber harvest on the Black Hills National Forest

Science Spotlights Posted on: March 23, 2021
A new report examines the standing sawtimber inventory of ponderosa pine on the Black Hills National Forest in South Dakota and Wyoming. The report looks at 60 scenarios to evaluate how mortality from disturbances (e.g., climate change, wildfire, beetle kill, etc.) and potential growth rates will impact short-, mid-, and long-term sustainable sawtimber harvest levels of ponderosa pine in the Black Hills.

Beetle Outbreaks in Subalpine Forests and What They Mean for Snowmelt

Documents and Media Posted on: February 08, 2021
  Rocky Mountain Research Station researchers used 17 years of data collected from the Forest Service’s Glacier Lakes Ecosystem Experiments Site (GLEES) in Wyoming’s Snowy Range to find that snow retained in tree canopies is quicker to sublimate (go directly from snow to water vapor) than snow on the ground, and ecosystem sublimation rates can be affected by factors that affect the amount of snow retained in the canopy.

Resolving management uncertainty: Detecting rare fish with environmental DNA

Science Spotlights Posted on: January 14, 2021
The mountain sucker has been declining in the Upper Missouri River Basin for unknown reasons. To address this uncertainty, a team of Forest Service researchers collected additional genetic data from these fish to find a section of DNA that is completely unique to this new species and developed an environmental DNA assay to detect this unique DNA fragment in water samples with increased accuracy. 

Tree regeneration following wildfires in ponderosa pine forests

Events Posted on: December 07, 2020
In this webinar, Paula Fornwalt discussed a recent project that examined post-fire tree regeneration in ponderosa pine forests of Arizona, Colorado, Wyoming, and South Dakota.

Improved carbon flux measurements in cold, snow covered ecosystems

Science Spotlights Posted on: October 30, 2020
In cold ecosystems, the annual carbon balance can be dominated by winter respiration. However, the eddy-covariance technique, a common methodology to measure net ecosystem exchange of carbon, can be inaccurate in cold climates due to the effect a warm sensor has on its gas measurement. Often, this error can make an otherwise dormant ecosystem appear as a carbon sink. Recently, RMRS researchers investigated and revised a common correction for this phenomenon.

Looking Into the Past: How Reconstructing Historical Forest Conditions Can Help Future Restoration Efforts

Documents and Media Posted on: September 22, 2020
Scientists from the Rocky Mountain Research Station, Colorado Forest Restoration Institute, and Rocky Mountain Tree Ring Research reconstructed historical forest conditions in Front Range forests that had adapted to survive frequent fire prior to 1860. Document Type: Other Documents

Improving identification of unusual bark beetles attacking lodgepole pine in the southern Rocky Mountains

Science Spotlights Posted on: September 02, 2020
Lodgepole pine growing above 9,000 feet have been under attack by a Dendroctonus insect other than the mountain pine beetle for several years. Trees are not dying as fast as expected. Identifying this beetle species required a new approach.

The scent of success: Beetle 'smells' can help protect the environment from weeds

Science Spotlights Posted on: August 31, 2020
Saltcedar (Tamarix spp.), an aggressively invasive Eurasian tree, is a dominant and widespread woody riparian species in the southwestern U.S. Biocontrol of saltcedar with the leaf beetle Diorhabda carinulata can be made more effective with semiochemicals (smells).
