Science Spotlights

Since the 1980s, it’s been assumed that forest soils require a long time to recover from a disturbance such as a timber harvest. The results of a 22-year monitoring study on the Kootenai National Forest counter this assumption. Certain types of forest soils showed a recovery within five to seven years following a timber harvest and subsequent fuels treatments.

Human activity has led to a global decline in biodiversity across all trophic levels, reducing the ability of ecosystems to maintain key functions. The loss of various species in an ecosystem has wide-reaching effects by reducing the numerous and often hidden species-species and species-environment interactions. These disruptions ultimately lead to changes and declines in the ecosystem’s functionality.

The 20th Century was a period of enormous change for western forests. Fire used to maintain distinct forest vegetation communities – pine, dry mixed-conifer, mesic mixed-conifer, and spruce-fir – in close proximity to one another along steep vertical gradients in the topographically diverse forests of the American Southwest. How did these forests change in response to fire exclusion? In what ways and how rapidly? What are the consequences of...
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.

Every year, groups of the birds congregate at mating areas called “leks” — areas that are used every year unless they’re disrupted. Because of the location specific nature of their mating process, greater sage-grouse are particularly vulnerable to habitat disruption.

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.
Fire Danger Rating System
The National Fire Danger Rating System (NFDRS) is a system that allows fire managers to estimate today's or tomorrow's fire danger for a given area. In 2014, RMRS fire danger rating system developers sought and gained approval to update the U.S. National Fire Danger Rating System (NFDRS).

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.

The management of Canada lynx habitat is an issue that has generated much debate and litigation across the Northern (Montana, Idaho) and Southern (Colorado, Wyoming) Rocky Mountains. This species depends almost exclusively on snowshoe hare for food during winter, and this prey species is sensitive to changes in forest composition and structure. Research conducted by scientists at the Rocky Mountain Research Station, in collaboration with...
Wildfire burn near a housing development
Wildfires are intensifying due to climate change, and more people are living in regions prone to fire. Understanding how individuals threatened by a wildfire make evacuation decisions – especially those who do not leave promptly – is necessary in order to foster public safety. Homeowners in three communities that have experienced wildfires in the United States were surveyed regarding their responses to evacuation requests.
