Assessing wildfire risk to communities and to natural and cultural resources

Science Spotlights Posted on: August 21, 2015
Rocky Mountain Research Station scientists affiliated with the National Fire Decision Support Center worked closely with the Agency's Western and Eastern Threat Centers to develop novel methods to assess wildfire risk to communities, watersheds, and wildlife habitat, and to developed, natural, and cultural resources. 

Fertilization in western larch forests

Documents and Media Posted on: August 20, 2015
Forest fertilization is effective as one means of increasing timber production. This report describes the status of fertilization research in the western larch type in Montana, and lists the locations of established experimental forest fertilization plots. Document Type: White Papers

Larix occidentalis Nutt.: Western larch

Documents and Media Posted on: August 20, 2015
Western larch (Larix occidentalis), a deciduous conifer, is also called tamarack and western tamarack; less commonly used names are hackmatack, mountain larch, and Montana larch. It is largest of the larches and is the most important timber species of the genus. Western larch is used for lumber, fine veneer, poles, ties, mine timbers, and pulpwood.

Missing mountain water

Science Spotlights Posted on: August 13, 2015
New understanding has revealed that declines in snowpacks are not just related to warming temperatures but also to overall decreases in precipitation and streamflow in northwestern U.S. mountains, which result from slowing winter westerly windspeeds over the region. Warming related to an increased atmospheric CO2 may have contributed to the changed atmospheric pressure patterns that result in reduced wind speeds.

Mild winters not causing all mountain pine beetle outbreaks in western U.S.

FS News Posted on: August 12, 2015
What is really driving mountain pine beetle population outbreaks in the U.S.? A new study shows increasing minimum winter temperatures explain some, but not all outbreaks.

Trout climate change refuge streams identified through extensive inter-agency crowdsourced databases

FS News Posted on: August 12, 2015
Using crowdsourced datasets compiled from dozens of resource agencies, the Climate Shield project brings together stream temperature and fish survey data to create information for identifying critical watersheds and streams.

Invasive plant erodes bird song diversity via food chain effects

Science Spotlights Posted on: May 20, 2015
Invasive plant impacts on native plants can ripple through native food webs from plants to insects all the way to birds. We observed that the invasion of spotted knapweed into grasslands of western Montana affects not only breeding success of songbirds but also the way song is passed between generations. 

Detection and range delineation of bull trout using environmental DNA

Science Spotlights Posted on: May 20, 2015
The bull trout is an ESA-listed species that relies on cold stream environments across the Northwest and is expected to decline with climate change. Resource managers from dozens of agencies are charged with maintaining bull trout in thousands of streams, but monitoring this species is difficult. Environmental DNA (eDNA) is much faster, easier, and more sensitive than traditional fish sampling methods and provides an opportunity to better delineate populations of federally threatened species like bull trout.

Improving access to habitat models to inform forest management plans

Science Spotlights Posted on: May 20, 2015
Habitat suitability models provide critical information needed for forest management plans to accommodate biodiversity conservation. We are developing GIS-based application tools for forest managers that requires minimal technical expertise to create habitat maps.

Assessing interactions of mountain pine beetles, fire, and vegetation dynamics to model wildlife habitat suitability under alternative climate and management scenarios

Projects Posted on: May 20, 2015
Synergistic interactions of climate change, mountain pine beetle infestations, and wildfire are likely to catalyze landscape-scale changes in vegetation distributions, successional stage, forest structure, and wildlife habitat suitability. Our research will provide forest managers with information they need to project changes to habitat suitability for wildlife under a range of alternative climate and management scenarios.
