Rare carnivore detections from environmental DNA in snow

Media Gallery Posted on: September 05, 2019
A new project showed that animal footprints in snow contain enough DNA for species identification, even when the snow was many months old. The study extracted DNA from snow samples collected within animal tracks as well as areas where the animal had been photographed months earlier. Newly developed genetic assays were applied and positively detected the DNA of each species, performing nearly flawlessly on samples previously considered too poor to provide usable DNA. This method could revolutionize winter surveys of rare species by greatly reducing or eliminating misidentifications and missed detections.

Managing forests and forest carnivores: Canada lynx and forest mosaics

Science Spotlights Posted on: September 07, 2018
The management of Canada lynx habitat is an issue that has generated much debate and litigation across the Northern (Montana, Idaho) and Southern (Colorado, Wyoming) Rocky Mountains. This species depends almost exclusively on snowshoe hare for food during winter, and this prey species is sensitive to changes in forest composition and structure. Research conducted by scientists at the Rocky Mountain Research Station, in collaboration with universities and local forest managers, is central in resolving management impasses by learning how changes in forest structure and composition can be implemented in ways that enhance the ability of Canada lynx to produce kittens.

Recreating in color: Promoting ethnic diversity on public lands

Documents and Media Posted on: May 30, 2018
Recent studies of the Forest Service’s National Visitor Use Monitoring (NVUM) data show a wide disparity in racial and ethnic use of national forests. Researchers at the Rocky Mountain Research Station in Fort Collins, Colorado, are studying NVUM numbers systematically and hope that their research will help National Forest System staff to encourage different racial and ethnic groups to connect with public natural lands.

Seeing red: New tools for mapping and understanding fire severity

Pages Posted on: May 14, 2018
Large, severe fires are ecologically and socially important because they have lasting effects on vegetation and soils, can potentially threaten people and property, and can be costly to manage. The goals of the Fire Severity Mapping Project(FIRESEV), which covers lands in the continental western United States, are to understand where and why fires burn severely, and to give fire managers, fire ecologists, and natural resource managers tools to assess severity before, during, and after a wildfire. FIRESEV has produced a suite of tools for a wide range of fire management applications, including real-time forecasts and assessments in wildfire situations, post-wildfire rehabilitation efforts, and long-term planning.

Hybridization between Dalmatian and yellow toadflax

Media Gallery Posted on: May 12, 2017
Two closely related invasive Linaria species, Dalmatian toadflax and yellow toadflax, have successfully invaded a broad range of ecosystems throughout most of continental North America. The management challenge imposed by the landscape scale of many toadflax infestations, particularly in the West, is further complicated by hybridization between these two weeds.

Looks aren’t everything: Hybridization between dalmatian and yellow toadflax

Science Spotlights Posted on: May 11, 2017
Two closely related invasive Linaria species, Dalmatian toadflax (Linaria Dalmatica) and yellow toadflax (Linaria vulgaris), have successfully invaded a broad range of ecosystems throughout most of continental North America. The management challenge imposed by the landscape scale of many toadflax infestations, particularly in the West, is further complicated by hybridization between these two weeds. Herbicide and biological control treatments for invasive Linaria are highly species-specific, necessitating the development of a molecular diagnostic tool to accurately confirm when cryptic hybridization has spontaneously occurred in the field, and habitat suitability modeling to predict areas most vulnerable to hybrid invasion.

National forest climate change maps: your guide to the future

Projects Posted on: April 17, 2017
The National Forest Climate Change Maps project was developed to meet the need of National Forest managers for information on projected climate changes at a scale relevant to decision making processes, including Forest Plans.  The maps use state-of-the-art science and are available for every National Forest in the contiguous United States with relevant data coverage. Currently, the map sets include variables related to precipitation, air temperature, snow (including April 1 snow-water equivalent (SWE) and snow residence time), and stream flow.
