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.

Fire patterns in piñon and juniper in the Western United States: Trends from 1984 through 2013

Science Spotlights Posted on: May 15, 2018
Changes in fire patterns for piñon and juniper vegetation in the western United States were analyzed over a 30-year period. This is the first evaluation of its type.

What drives low-severity fire in the southwestern United States?

Science Spotlights Posted on: May 15, 2018
Dry conifer forests in the Western United States historically had low impact surface fires approximately every five to 30 years. Due to more than 100 years of successful fire exclusion, however, many of these forests are now denser, and therefore have a greater probability of experiencing intense fires that burn entire stands and convert forests to non-forest landscapes. What environmental conditions are necessary to promote low-severity fire in dry conifer forests? Causes and consequences of high-severity fires are increasingly being studied but little to no research has focused on factors that promote low-severity fires, until now.

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.

Can FIA soils data improve models predicting ponderosa pine density in the Southwest?

Projects Posted on: August 25, 2017
Puhlick et al. (2012) evaluated the influence of numerous abiotic and biotic factors on ponderosa pine regeneration densities in the southwestern United States. The study described here will use newly released soils data from the Forest Inventory and Analysis program to test the influence of soils and other variables on ponderosa pine seedling densities.

Spatial patterns of ponderosa pine regeneration in high-severity burn patches

Science Spotlights Posted on: August 25, 2017
Over the past three decades, wildfires in southwestern United States ponderosa pine forests have increased in size and severity, leaving large patches of tree mortality. Ponderosa pine evolved under fire regimes dominated by low- to moderate-severity wildfires, and they are poorly adapted to regenerating in large patches of high-severity fire. There is concern about these high-severity burn patches because the lack of seed-producing trees can prevent or significantly delay ponderosa pine regeneration.

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.
