Developing pollinator-dependent plant materials for use in a growing restoration economy

Projects Posted on: March 08, 2019
Located on the Sierra Ancha Experimental Forest, this project uses a common garden approach to determine which plant species are best suited for supporting pollinator communities and are most appropriate for restoration activities. Findings from the study will be used to 1) improve pollinator habitat, 2) increase seed stocks of native flowering species for use in restoration, 3) inform U.S. seed zone guidelines and 4) help predict plant-pollinator response to climate change. This carries on a long tradition at the Sierra Ancha Experimental Forest of using common gardens in botanical research. As far back as the 1920s and 30s common gardens were used to study evapotranspiration rates of native herbaceous and shrub species as well as evaluate the potential use of certain species for erosion control. Some of these the same gardens are now being restored nearly a century later for use in this study.

Sierra Ancha Experimental Forest Vegetation Mapping Project

Projects Posted on: March 08, 2019
The Sierra Ancha Experimental Forest (SAEF) Vegetation Mapping Project uses unmanned aerial vehicles (UAVs) to create highly detailed vegetation maps using Structure From Motion technology.  These maps are then used to overlay historical vegetation maps made nearly 100 years ago to determine how vegetation has changed over the last century.

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.

Sierra Ancha Experimental Forest

Experimental Forests and Ranges Posted on: September 09, 2015
The U.S. Forest Service established the Sierra Ancha Experimental Forest in 1932 as a research area for studying watershed management. Located within the Tonto National Forest, the climate, soil, and landforms of the Sierra Ancha are representative of much of the southwestern region of the United States.
