Floral scent guides bee-flower interactions and explains seasonal patterns in communities

Science Spotlights Posted on: October 21, 2019
In diverse communities, bees visit flowers of plants, forming complex webs of interactions. The structure of these webs can tell us about how communities function and guide their conservation and restoration, yet we know little about the cues that regulate these webs. We analyzed floral scent of 47 plant species and bee visitors across the growing season in a meadow community and found that floral scent is a key cue structuring bee-forb interactions.

Soil survey of Gallatin National Forest, Montana

Documents and Media Posted on: November 20, 2018
This soil survey contains information that can be used in land-planning programs in the survey area. The landforms, natural vegetation, and bedrock were studied to a greater extent than usual in soil surveys in order to define and interpret map units. Surveys such as this one have been referred to in Forest Service publications as "land system inventories" or "integrated inventories." The map units have been called "landtypes." Document Type: Other Documents

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.

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.

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.

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.

Mapping climate refugia to preserve cold-water biodiversity using crowd-sourced databases

Science Spotlights Posted on: September 20, 2016
Concerns about climate change effects on cold-water biodiversity sparked broad multi-agency collaborative efforts throughout the American West. U.S. Forest Service research teams led development of massive interagency databases that now enable precise mapping of critical habitats and species distributions in streams flowing through 101 National Forests.

Optimization technique identifies cost-effective biodiversity corridors

FS News Posted on: September 06, 2016
A new optimization technique could help conservation biologists choose the most cost-effective ways of connecting isolated populations of rare, threatened and endangered species living in protected areas. As the human population grows and expands its footprint, maintaining the connectivity of animal habitats is a challenge. Habitat corridors are critical for keeping wildlife species connected across the landscape.
