1965 tamarisk point data for the Colorado Plateau ecoregion, USA Over the past 100 years, species of non-native tamarisk (Tamarix spp.) have invaded perhaps hundreds of thousands of acres in riparian zones and desert washes throughout the semi-arid, west and southwest United States (Robinson 1965, Cleverly et al. 1997). Large stands of tamarisk transpire vast amounts of precious water supplies, negatively alter soil chemistry, and out-compete native plant species (Zimmerman 1997, Di Tomaso 1998, Smith et al. 1998, Zavaleta 2000). Tamarisk is a prolific seeder, consummate resprouter, and is fire tolerant. Tamarisk has negative effects on many wildlife species, but it can act as marginal replacement habitat for some...

Difference of Average Winter (Jan-Mar) 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....

LANDFIRE disturbance data are developed to provide temporal and spatial information related to landscape change for determining vegetation transitions over time and for making subsequent updates to LANDFIRE vegetation, fuel and other data. Disturbance data include attributes associated with disturbance year, type, and severity. These data are developed through use of Landsat satellite imagery, local agency derived disturbance polygons, and other ancillary data. DATA SUMMARY: The disturbance data are developed through a multistep process. Inputs to this process include; Landsat imagery and derived NBR (normalized burn ratio) data; polygon data developed by local agencies for the LANDFIRE Refresh effort; fire data...

This dataset provides an estimate of aquatic biodiversity sites, based on protected and conservation lands superimposed on the NHD flowlines dataset. Caution is warrented in interpreting this dataset. While measures of aquatic biodiversity exist, they are based on localized samples that cannot be extrapolated beyond the sampling domain. These measures were not included in this dataset. Instead, it was assumed that areas within TNC Portfolio areas were identified for factors that include high aquatic biodiversity. Furthermore, it is assumed that aquatic biodiversity is higher in protected areas due to stricter controls over land and water management. However, this assumption may not be valid for stream reaches that...

The distribution and abundance of Colorado River cutthroat trout (Oncorhynchus clarkii pleuriticus; CRCT) have declined from historical levels over their entire range. For this CRCT assessment we used existing information provided by 48 fisheries professionals applied through a consistent methodology to assess the extent of CRCT historical range, their current distribution, including genetic status, and evaluated the foreseeable risks to 285 populations designated as "conservation populations" by management agencies. We estimated CRCT historically occupied about 21,386 miles of habitat in the western U.S. CRCT currently occupy about 3,022 miles of habitat in 51 of the 61 4th level HUCs historically occupied. Of...

In a step towards implementing our Vision, SREP completed a statewide assessment of wildlife linkages in collaboration with the Colorado Department of Transportation (CDOT), the Federal Highway Administration, The Nature Conservancy, and Colorado State University, identifying and prioritizing wildlife linkages across the state of Colorado. The goal of this work is to provide transportation planners, state and federal agencies, community leaders, engineers, and conservationists with a statewide vision for reconnecting habitats that are vital for maintaining healthy populations of native species. Both the Federal Highway Administration and CDOT have begun promoting wildlife crossings in their transportation plans...

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. EVH is determined by the average height weighted by species...

This dataset shows the current distribution of Inter-Mountain Basins Montane Sagebush Steppe (NatureServe Landcover) within the context of current and near-term terrestrial intactness and long-term potential for energy development and potential for climate change (4KM reporting units). Current terrestrial intactness is based on current measures of landscape development, fire regime and vegetation impacts, and fragmentation. Near-term intactness includes estimates of urban growth and expansion of invasive vegetation. Long-term potential for energy development is based on areas of potential for wind, solar, and petroleum development derived from multiple sources. Long-term potential for climate change is based on...

This dataset represents PRONGHORN use areas in Utah as determined by wildlife biologists first during 2001. The data for Carbon, Emery, Grand, Wayne, Garfield, and San Juan were updated by state and federal agency biologists March 2004. Another update was completed in November 2004 in conjunction with the Richfield BLM RMP process. An update in Uintah county by UDWR biologists was completed in January 2006. In May 2006 the dataset was converted from a Critical, High, Substantial and Limited value system to a Crucial/Substantial value system. In 2010, Uintah county biologist added two crucial yearlong areas to the file. Data for use at 1:100,000 scales.

This dataset shows a series of fragmentation metrics for natural vegetation for a 4KM reporting unit. These metrics were calculated using FRAGSTATS. For more information about FRAGSTATS, or the methods used to calculate these metrics, please see: http://www.umass.edu/landeco/research/fragstats/fragstats.html Fragmentation metrics were caculated for a 3x3 reporting unit grid (4KM each) neighborhood centered on each reporting unit grid cell. This was done to prevent edge effects due to the smaller size of the reporting units relative to the size of larger patches in more intact landscapes. A 90 meter edge distance was used to define core area within patches.

New invasions, better field data, and novel spatial modeling techniques often drive the need to revisit previous maps and models of invasive species. Such is the case with the at least 10 species of Tamarix, which are invading riparian systems in the western United States and are expanding their range throughout North America. In 2006, we developed a National Tamarisk Map using a compilation of presence and absence locations with remotely sensed data and statistical modeling techniques. Since the publication of that work, our database of Tamarix distributions has grown significantly.Using the updated database of species occurrence, new predictor variables, and the Maximum entropy (Maxent) model, we have revised...

Because of the potential for reindeer to commingle into caribou herds when the two occupy the same range or when caribou migrate through reindeer range, areas within current caribou herd summer ranges were considered to have low biological potential to support reindeer herding for calving season and summer. Similarly, areas within the current herd annual ranges were considered to have low biological potential to support reindeer herding for late fall, winter, and early spring. Areas of moderate and good quality forage occurred both within and outside of caribou herd ranges for both assessed seasons within the Central Yukon study area but to widely differing extents. The summer ranges of all caribou herds covered...

Increasing temperatures across the region will cause a lengthening of the growing season and an increase in heat accumulation (measured as summer warmth index) during summer months. These changes could have profound effects on phenology, plant growth, water availability, and species distributions. July temperature isotherms and SWI have been used to help define vegetation distribution and potential for vegetation change across the boreal and arctic biomes. The northern limit of the boreal forest occurs approximately at the 12°C mean July isotherm and a SWI of 35°C mo, and strong linkages have been described between SWI and treeline advance. The southern boundary for the boreal forest occurs at approximately the...

Elodea (waterweed) is widely recognized as a serious threat to the ecology of freshwater systems – this plant can achieve dense monospecific stands, reduce the flow of water, and alter the chemical composition of the water body, including hyper-eutrophication and oxygen depletion. It is native to North America south of the limit of the former Laurentide ice sheet, south of the southern US-Canada border. This species was first recorded in Alaska in 1982 and in recent years the number of known sites has increased dramatically, especially in those with high use. Historic and future scenarios for elodea climate suitability was based on associations of known locations of Elodea worldwide with 23 climate and topographic...
