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

Pages Posted on: December 14, 2015
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.

Forest habitat types of central Idaho

Publications Posted on: February 14, 2012
A land-classification system based upon potential natural vegetation is presented for the forests of central Idaho. It is based on reconnaissance sampling of about 800 stands. A hierarchical taxonomic classification of forest sites was developed using the habitat type concept. A total of eight climax series, 64 habitat types, and 55 additional phases of habitat types are defined and described.

Coniferous forest habitat types of central and southern Utah

Publications Posted on: February 02, 2010
A land-classification system based upon potential natural vegetation is presented for the coniferous forests of central and southern Utah. It is based on reconnaissance sampling of about 720 stands. A hierarchical taxonomic classification of forest sites was developed using the habitat type concept. Seven climax series, 37 habitat types, and six additional phases of habitat types are defined and described.

Effects of plot size on forest-type algorithm accuracy

Publications Posted on: July 15, 2009
The Forest Inventory and Analysis (FIA) program utilizes an algorithm to consistently determine the forest type for forested conditions on sample plots. Forest type is determined from tree size and species information. Thus, the accuracy of results is often dependent on the number of trees present, which is highly correlated with plot area.

Forest habitat types of eastern Idaho-western Wyoming

Publications Posted on: May 15, 2009
A land-classification system based upon potential natural vegetation is presented for the forests of central Idaho. It is based on reconnaissance sampling of about 980 stands. A hierarchical taxonomic classification of forest sites was developed using the habitat type concept. A total of six climax series, 58 habitat types, and 24 additional phases of habitat types are defined and described.
