Science Spotlights

Although not presented in textbooks, open forests were the dominant historical forested ecosystems of the United States. Eastern and western oak forests and southeastern pine forests no longer occur at landscape scales. Management for open oak and pine forests will provide herbaceous habitat, critical to many declining bird and pollinator species.
Big sage mountain brush
An unprecedented conservation effort is underway across 11 Western states to address threats to sagebrush ecosystems and the many species that depend on them. Today, the Department of Agriculture and the Department of Interior released the Science Framework for Conservation and Restoration of the Sagebrush Biome (Part 2). The Science Framework provides a transparent, ecologically responsible approach for making policy and management decisions...
National Genomics Center stream water filter setup for eDNA sample collection
The National Genomics Center for Wildlife and Fish Conservation pioneered development of eDNA sampling of aquatic environments at their laboratory in Missoula, MT. The Center has partnered with dozens of National Forests, as well as other state, federal, tribal, and private natural resource organizations to assist in the collection and processing of eDNA samples. Thousands of eDNA samples are collected annually and constitute a rapidly growing...

This research looks at opportunities to utilize traditional phenological knowledge to support adaptive management of social-ecological systems vulnerable to changes in climate and fire regimes. Integrating phenological knowledge into natural resource stewardship is important in making land management decisions. Indigenous knowledge of seasonal change adds a broader ecological knowledge base in the context of changing and vulnerable social and...
Effective conservation and management decisions for habitats require information about the distribution of multiple species but such data is expensive to obtain; this often limits data collection to just a few, high-profile species. Environmental DNA (eDNA) sampling can be more sensitive, and less expensive, than traditional sampling for aquatic species, and a single sample potentially contains DNA from all species present in a waterbody. Cost-...
Collaborative Forest Landscape Restoration Program (CFLRP) treatment implementation on the Pike-San Isabel National Forest, Colorado.
New novel study expands the scope of monitoring efforts in one of the first USDA Forest Service Collaborative Forest Landscape Restoration Program (CFLRP) landscapes, Colorado’s Front Range. Results from this study highlight both the effective aspects of restoration treatments, and the importance of initiating and continuing collaborative science-based monitoring to improve the outcomes of forest restoration efforts.

The Bengal tiger is the world’s largest feline, which has suffered immense declines in range and population. Today, less than 10 percent of the tiger's original range is occupied with a global population of less than 7000 individuals in the wild. Understanding the factors that drive local abundance and population connectivity are critical for the conservation of this species.  
Example of a forest structure suitable for northern goshawks and producing high quality timber
Wildlife habitat and timber production are critical elements of the management of many National Forests. The Black Hills National Forest has provided a thriving timber economy for over 100 years. The forest also provides habitat for the northern goshawk, which has been severely impacted by mountain pine beetles. 
The Mexican spotted owl is listed as a Threatened Species under the Endangered Species Act and is vulnerable to habitat loss from wildfire and climate change. RMRS scientists are leading a cutting-edge modeling effort to predict the interactive effects of forest restoration, wildfire, and climate change on the distribution, population size, and population connectivity of Mexican spotted owl across the Southwestern United States.

A frequently discussed function of aridland riparian ecosystems is the contribution of woody riparian plants to breeding bird habitat. The structurally diverse, species-rich vegetation along many southwestern streams supports high densities of territories and nest sites for a variety of birds including several species of high conservation priority.A frequently discussed function of aridland riparian ecosystems is the contribution of woody...
