Difference of Average Summer (Jul-Sep) Temperature (2045-2060 vs 1968-1999) simulated by RegCM3 with GENMOM projections as boundary conditions. Units are degrees Celsius. These data were generated by the regional climate model RegCM3 with boundary conditions from a GCM future climate projections. The data were downscaled statistically by calculating differences (anomalies) between the RegCM3 results with GCM-driven boundary conditions for 1968-99 and those for a future period, in this case 2015-2030. The anomalies were added (temperatures) or multiplied (precipitation) to a climate baseline from PRISM (Parameter-elevation Regressions on Indepenent Slopes Model - prism.oregonstate.edu) data based on historical observations....
Broad-scale alterations of historical fire regimes and vegetation dynamics have occurred in many landscapes in the U.S. through the combined influence of land management practices, fire exclusion, ungulate herbivory, insect and disease outbreaks, climate change, and invasion of non-native plant species. The LANDFIRE Project produces maps of simulated historical fire regimes and vegetation conditions using the LANDSUM landscape succession and disturbance dynamics model. The LANDFIRE Project also produces maps of current vegetation and measurements of current vegetation departure from simulated historical reference conditions. These maps support fire and landscape management planning outlined in the goals of the National...
This dataset depicts the density (percent of 4km grid cell occupied) by major invasive vegetation species. The current distribution of major vegetation species was developed for this REA from a combination of source datasets. Please see the metadata for that dataset (Raster\Change_Agents\Invasives\Inv_Current\cop_iv_cs) for more information about how it was created.
This dataset provides an estimate of near-term terrestrial intactness, based on a fuzzy logic model that integrates multiple measures of landscape development and vegetation intactness. A powerpoint version of the logic model is available at: Vector\Conservation_Elements\Terrestrial\Ecosystem\Documentation\COP_TI_logic_models.pptx This model integrates agriculture development (from LANDFIRE EVT v1.1), urban development (from LANDFIRE EVT v1.1 and NLCD Impervious Surfaces, combined with estimates of urban growth from David Theobald), linear development (from BLM GTLF, utility lines, and pipelines), energy and mining development (from state mine and USGS national mines datasets as well as AZ uranium mines, geothermal...

Difference of Annual Total Precipitation (2045-2060 vs 1968-1999) simulated by RegCM3 with ECHAM5 projections as boundary conditions, normalized by the standard deviation of PRISM (1968-1999) average total annual precipitation. These data were generated by the regional climate model RegCM3 with boundary conditions from a GCM future climate projections. The data were downscaled statistically by calculating differences (anomalies) between the RegCM3 results with GCM-driven boundary conditions for 1968-99 and those for a future period, in this case 2015-2030. The anomalies were added (temperatures) or multiplied (precipitation) to a climate baseline from PRISM (Parameter-elevation Regressions on Indepenent Slopes Model...
The LANDFIRE existing vegetation layers describe the following elements of existing vegetation for each LANDFIRE mapping zone: existing vegetation type, existing vegetation canopy cover, and existing vegetation height. Vegetation is mapped using predictive landscape models based on extensive field reference data, satellite imagery, biophysical gradient layers, and classification and regression trees.DATA SUMMARY: The existing vegetation type (EVT) data layer represents the current distribution of the terrestrial ecological systems classification developed by NatureServe for the western Hemisphere (http://www.natureserve.org/publications/usEcologicalsystems.jsp). A terrestrial ecological system is defined as a group...
This dataset depicts land-based recreation travel corridors. Very little information is available for land-based recreation travel, thus we were forced to create this dataset as an initial estimate of linear features that may be used for recreation. This dataset is a combination of national trails, and non-highway features from BLM's ground transportation linear features dataset clipped to federal and state lands (except Dept. of Defense lands). Given absence of additional information, it could be assumed that many roads and trails within public lands could be used for recreation travel of one form or another. Insufficient information is available to categorize the types of recreation that may occur on these features....

4KM grid cell reporting units for the Colorado Plateau Ecoregion Used as analytical reporting unit for terrestrial conservation elements and terrestrial intactness.
Difference of Average Annual Temperature (2015-2030 vs 1968-1999) simulated by RegCM3 with ECHAM5 projections as boundary conditions. Units are degrees Celsius. These data were generated by the regional climate model RegCM3 with boundary conditions from a GCM future climate projections. The data were downscaled statistically by calculating differences (anomalies) between the RegCM3 results with GCM-driven boundary conditions for 1968-99 and those for a future period, in this case 2015-2030. The anomalies were added (temperatures) or multiplied (precipitation) to a climate baseline from PRISM (Parameter-elevation Regressions on Indepenent Slopes Model - prism.oregonstate.edu) data based on historical observations....

Difference of Average Winter (Jan-Mar) Precipitation (2045-2060 vs 1968-1999) simulated by RegCM3 with GENMOM projections as boundary conditions. Units are millimeters. These data were generated by the regional climate model RegCM3 with boundary conditions from a GCM future climate projections.

This dataset shows an estimate of the probability of human-caused fire occurrence, based on 30 years of occurrence data using a MaxEnt model based on several factors including distance to roads, urban areas, vegetation type, and climate. This long-term estimate is based on projecting the Maxent model developed on current climate conditions onto downscaled climate projections from RegCM3 based on ECHAM5 boundary conditions. Model performance was poor to fair, with an AUC of 0.674 Significant predictive factors include distance to recreation areas, annual precipitation, distance to roads, summer precipitation, and existing vegetation type. Caution should be exercised in interpreting this dataset, as it is based on...

These digital maps are a reformulation of previously published maps, primarily maps of states. The reformulation gives all the maps the same structure and format, allowing them to be combined into regional maps. The associated data tables have information about age and lithology of the map units, also in a standard format.

The LANDFIRE existing vegetation layers describe the following elements of existing vegetation for each LANDFIRE mapping zone: existing vegetation type, existing vegetation canopy cover, and existing vegetation height. Vegetation is mapped using predictive landscape models based on extensive field reference data, satellite imagery, biophysical gradient layers, and classification and regression trees.DATA SUMMARY: The existing vegetation height (EVH) data layer is an important input to LANDFIRE modeling efforts. Canopy height is generated separately for tree, shrub and herbaceous cover life forms using training data and a series of geospatial data layers. Plots from the Forest Inventory and Analysis (FIA) program...
