Science Spotlights

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...
Trailing edge forest Southern Rockies ecoregion
Forests are an incredibly important resource across the globe, yet they are threatened by climate change through stressors such as drought, insect outbreaks, and wildfire. Trailing edge forests—those areas expected to experience range contractions under a changing climate—are of concern because of the potential for abrupt conversion to non-forest. However, broad-scale forest die-off and range contraction in trailing edge forests are unlikely to...
Sampling streamwater in watersheds of the Hayman Fire
Severe wildfires remove vegetation and organic soil layers and expose watersheds to erosion which can transport large quantities of soil and ash to nearby rivers and streams. But once the burned areas have stabilized, do severe wildfires have any longer-lasting effects on watersheds or water quality? This study follows the Hayman Fire, 2002, Colorado, and shows that yes, there are long-term effects.

Forage availability for grazing animals has always been vulnerable to the effects of variations of weather and climate from year–to–year, with some years and decades markedly drier than others.

Over the last decade, decisions surrounding the provenance, or the geographic origin of a seed source, has sparked a debate whether or not to use local native or nonlocal native seed. A new paper turns a traditionally theoretical discussion into specific priority actions for researchers and practitioners involved in restoration.
Standard wood stakes are used to evaluate wood decomposition rates within and among sites.
Maintaining woody debris on forest sites is critical for maintaining carbon stores and modeling the rate of decay helps managers understand tree growth and and carbon sequestration.

Anyone familiar with the Columbia River’s massive salmon die-off a few summers ago might also be concerned about how climate change will affect fish habitats. The 2015 die-off killed more than 250,000 fish and was blamed on record low streamflows and high water temperatures. While coldwater fish such as salmon and trout can adjust to slightly warmer-than-normal temperatures for short periods, abnormally high temperatures for prolonged periods...

Mountain fens (peat-accumulating wetlands) are groundwater-dependent habitats (i.e. groundwater dependent ecosystems) protected under the Clean Water Act and other federal mandates in the United States. There is increasing interest in documenting and monitoring the occurrence and characteristics of fens. In addition to supporting unusual plants, fens are sites of carbon and water storage and long-term ecological stability, since the underlying...

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.

Altered disturbance regimes and changing ecosystem dynamics in wilderness areas have increased the importance of having an evaluation framework to support transparent decision-making for ecological restoration actions. A recently created wilderness evaluation framework questionnaire allows for improved communication between land management agencies and wilderness stakeholders.
