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.

Choices in the face of uncertainty: Study points to thresholds and framing as major influencing factors

Science Spotlights Posted on: May 05, 2017
A new paper in the journal Climatic Change highlights human incentives for positive change in uncertain situations. The research shows that humans will take collective action to address a common problem if the problem, the amount of action needed to address the problem, and the potential consequences of not solving the problem are framed appropriately.

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.

Second edition of best-selling book on nonmarket valuation now available

FS News Posted on: April 13, 2017
With an ever-growing need to understand the monetary benefits of environmental conservation, the newly released second edition of “A Primer on Nonmarket Valuation” is a valuable resource for government and industry alike. The book provides common approaches to measuring nonmarket values for environmental assets, such as wilderness and water quality, for people around the globe.

Stream water quality after a fire

Projects Posted on: April 07, 2017
Wildland fires in the arid west create a cause for concern for many inhabitants and an area of interest for researchers. Wildfires dramatically change watersheds, yielding floods and debris flows that endanger water supplies, human lives, and valuable fish habitats.

Effects of prescribed fire on wildlife and wildlife habitat in selected ecosystems of North America

Effects of prescribed fire on wildlife and wildlife habitat in selected ecosystems of North America

Science Spotlights Posted on: March 28, 2017
Some objectives for prescribed fire include reducing fuel loads and fuel continuity, returning fire to an ecosystem, enhancing wildlife habitats, improving forage, preparing seedbeds, improving watershed conditions, enhancing nutrient cycling, controlling exotic weeds, and enhancing resilience from climate change. Regardless of the particular objective, fire affects ecosystem structure, composition, and function in many ways.

National flow gage gap analysis

Projects Posted on: March 16, 2017
Flow gages* record discharge in streams and rivers across the U.S. but the extent and adequacy of this monitoring network relative to USFS lands has not been documented. To address that deficiency, the medium resolution National Hydrography Layer was used with gage location information from the National Water Information System to describe the monitoring network and how it has changed through time.

Waste to Wisdom

Pages Posted on: March 10, 2017
Waste to Wisdom is an innovative biomass research project funded by a $5.88 million grant from the U.S. Department of Energy under the Biomass Research and Development Initiative program. Humboldt State University and 15 regional partners, including the Rocky Mountain Research Station, are building on existing research on the conversion of forest residues into bioenergy and other valuable bio-based products.

Global spread of invasive species

Projects Posted on: February 03, 2017
Thousands of species hitchhike in the ballast water of ships and on a ship’s hull and other exposed surfaces, and many are taking up residence in areas where they previously have not lived. Scientists, engineers, and economists have joined together to learn more about this problem of these species migrating around the globe.
