Snow retained in tree canopies is quicker to sublimate (go directly from snow to water vapor) than snow on the ground, and ecosystem sublimation rates can be affected by factors that affect the amount of snow retained in the canopy.

WindNinja is a microscale diagnostic wind model, developed for and widely used in operational wildland fire applications both in the United States and abroad.

Three forest types account for 65.2 percent of lower treeline in the Intermountain West: Colorado Plateau pinyon-juniper woodlands, Great Basin pinyon-juniper woodlands, and Northern Rocky Mountain dry mixed-conifer forests.

Landscapes are shifting in response to climate change and wildfire. Forests of the Huachuca Mountains are projected to undergo significant shifts in biomass, species distributions, and patterns of fire over 50 years of projected future climate.

A new GTR reviews timber harvest operations and their effects on soil sustainability to help forest managers understand and limit impacts and allow national forests to continue to produce ecosystem services and goods.

TreeMap is a new tree-level model of U.S. forests developed to support analysis of wildfire risk to carbon. It has a range of other management applications, from inventorying wildlife habitat to modeling the impacts of fuel treatments.

Part of these projections includes a separate assessment of annual herbaceous yield (e.g., cheatgrass), enabling managers to “see into the future.” These data are produced automatically on a weekly basis and are ready for managers and planners right now.

Across the Intermountain West, snowpack in forested headwaters is the primary, if not sole, water supply source for many communities. And the forests themselves play a crucial role in maintaining the snowpack and helping to deliver high-quality water to downstream communities.

Open forests, once common in the eastern United States, are defined by a fire-resistant overstory of trees and a diverse herbaceous layer that can be maintained by frequent low-intensity fires. These forests started disappearing with land-use changes and widespread management practices and are now rare in the landscape; many species associated with these forests have been lost or are on the decline. Restoration of open forests for the long term includes management of the herbaceous layer, continuity of the overstory, and managing tree regeneration, which can be accomplished with fire,...

Forest management at the Lick Creek Demonstration-Research Forest in the Northern Rocky Mountains of Montana has been documented in photographs since the early 1900s and since 1991 of the cut/burn treatments. These replicated photos show how quickly dry forests in the Rockies can change.
