Reclassifying the wildland–urban interface using fire occurrences for the United States

Science Spotlights Posted on: July 31, 2020
The wildland–urban interface (WUI) occurs at the intersection of houses and undeveloped wildlands, where fire is a safety concern for communities. Previous definitions of the WUI do not explicitly account for differences in fire risk, but data are now available to use objective measures of fire occurrence to refine the definition by assessing the housing densities where fires actually occurred.

The wildland–urban interface (WUI) occurs at the intersection of houses and undeveloped wildlands, where fire is a safety concern for communities, motivating investment in planning, protection, and risk mitigation.

Range condition classification of bunchgrass range at the Manitou Experimental Forest in Colorado

Publications Posted on: February 12, 2020
This paper indicates a method of judging range condition of grassland areas in the ponderosa pine forest of the Colorado Front Range based on relative herbage production of desirable forage species. The loop method of Parker (1951) is now widely used in range management. Data obtained by the method include measurements of vegetation (cover index, composition, and vigor) and soils and erosion (bare ground and litter).

Forested wetland area and distribution: A detailed look at the South

Publications Posted on: December 13, 2019
Debate over the classification, protection, and management of forested wetlands has intensified in recent years. Federal agencies have classified US wetlands in various manners, leading to frequent protests by groups favoring more or less stringent criteria.

Forest vegetation in the Rocky Mountain and Intermountain regions: Habitat types and community types

Publications Posted on: December 09, 2016
Habitat types and community types and their phases for the major forest tree species in the Rocky Mountain and Intermountain regions are tabulated. Included are the name(s), general location, elevation, relative site, successional status, principal tree and undergrowth associates, and the authority.

Taxonomy, phylogenetics and biogeography of Chesneya (Fabaceae), evidenced from data of three sequences, ITS, trnS-trnG, and rbcL

Publications Posted on: November 22, 2016
Plants of Central Asia have played a significant role in the origin of floras of Eurasia and the Northern Hemisphere.

Ecoregions are large areas of similar climate where ecosystems recur in predictable patterns. The Rocky Mountain Research Station provides resources and education on the origins of these patterns and their relevance to sustainable design and planning.

Relationships between riparian vegetation and geomorphic process zones in the Toiyabe mountain range in Nevada

Datasets Posted on: August 27, 2015
We conducted a field observational study to investigate the ecological significance of the "process zone" geomorphic classification scheme for riparian ecosystem distribution, composition, and structure. We measured geomorphic characteristics at multiple scales in order to better understand relationships between geomorphology and riparian vegetation, and to suggest improvements to the classification scheme.

Evaluating methods to detect bark beetle-caused tree mortality using single-date and multi-date Landsat imagery

Publications Posted on: February 28, 2013
Bark beetles cause significant tree mortality in coniferous forests across North America. Mapping beetle-caused tree mortality is therefore important for gauging impacts to forest ecosystems and assessing trends. Remote sensing offers the potential for accurate, repeatable estimates of tree mortality in outbreak areas.

Riparian reference areas in Idaho: A catalog of plant associations and conservation sites

Publications Posted on: December 31, 2012
Idaho land managers and regulators need knowledge on riparian reference sites. Reference sites are ecological controls that can be used to set meaningful management and regulatory goals. Since 1984, the Idaho Conservation Data Center, Boise, ID, has compiled information in a series of interrelated databases on the distribution and condition of riparian, wetland, and terrestrial plant associations in high quality reference sites in Idaho.
