The Alaska Exotic Plants Information Clearinghouse (AKEPIC) is a database and mapping application that provide geospatial information for non-native plant species in Alaska and neighboring Canadian Territories. These products are the result of an ongoing cooperation among the U.S. Forest Service, National Park Service, Bureau of Land Management, U.S. Fish and Wildlife Service, Department of Natural Resources Plant Material Center, and Alaska Center for Conservation Science in support of the Alaska Committee for Noxious and Invasive Plants Management (CNIPM) and the Strategic Plan for Noxious and Invasive Plants Management in Alaska. The Alaska Center for Conservation Science administers the mapping application,...
Rather than using the ARDF to determine future mining activity, which is a work in progress we used additional datasets. Future mines are difficult to predict but we used three datasets to represent future mining activity: Ambler mining belt, Nanushuk coal mine, and USGS mineral potential GIS database (Jones et al. 2015). Jones et al. (2015) documented the potential and certainty of six minerals deposit groups. The mineral resource potential datasets produced by the USGS (Jones et al. 2015) was used in conjunction with access to identify areas with the most likely long-term future mining activity. Mineral resource potential datasets only cover a portion of our study area (63.9% or 252,845 km2) but can still provide...
This dataset was developed for the BLM Rapid Ecoregional Assessment for the Central Yukon study area and represents the most recent available annual distribution for the Terrestrial Fine-Filter Conservation Element caribou: Porcupine Herd. The Porcupine Caribou Management Board maintain radio collar and satellite telemetry data for the Porcupine Herd across Alaska, Yukon, and Northwest Territories. Radio collar and satellite telemetry data were not made available to Alaska Center for Conservation Science (ACCS) for the Rapid Ecoregional Assessment (REA). However, collar location data points were used by Griffith et al. (2002) to determine the 1983 to 2001 total annual range for the Porcupine Herd. The total annual...
Although future roads are included in the long-term LCM, we conducted separate spatial analyses intersecting the future layers with our fish distributions to identify the projects or watersheds with the potential to impact fish species of conservation concern. Four datasets were used to represent future road construction in the study area: preferred routes to Nome, Umiat, and Ambler; and proposed forestry roads. These roads were intersected with the distributions of Dolly Varden. The anadromous Dolly Varden habitat distribution and modeled resident Dolly Varden habitat distribution for the 2060s were combined into a single distribution for this analysis. Road intersections were highest for Dolly Varden because Dolly...
Caribou typically undergo seasonal migrations between summer calving grounds, mosquito-relief areas and winter foraging sites, with migration distances varying amongst herds. In the CYR study area, the larger, arctic herds, undergo seasonal migrations of distances up to 640 km, with annual movements of some caribou totaling more than 5000 km; while the smaller, more regional herds farther south, tend to undergo much shorter seasonal movements. Wider ranging herds include the Western Arctic, Central Arctic and Porcupine herds. The more localized herds include the Fortymile, Galena, Hodzana Hills, Macomb, Ray Mountains, White Mountains and Wolf Mountain herds. The Western Arctic herd has the largest range and most...

Leaf Area Index simulated by the biogeography model MAPSS using RegCM3 climate with ECHAM5 projections as boundary conditions. MAPSS (Mapped Atmosphere-Plant-Soil System) is a static biogeography model that projects potential vegetation distribution and hydrological flows on a grid (http://www.databasin.org/climate-center/features/mapss-model). MAPSS has been used widely for various climate change assessments including the 2000 National Assessment Synthesis Team's report. MAPSS uses long term, average monthly climate data (mean monthly temperature, vapor pressure, wind speed, and precipitation) as well as soils information (texture, depth). Based on a set of climatic thresholds, the model defines the following plant...
This dataset depicts the near term (2015-2030) predicted distribution of major invasive vegetation species in the Sonoran Desert Ecoregion. It shows the combination of all areas predicted to have current distribution of invasive vegetation species, in addition to areas predicted in the near term Sahara mustard probability model, based on near term climate (2015-2030, derived from RegCM3 based on ECHAM5 boundary conditions). This dataset does not show range contractions of invasive vegetation species, only range expansions, due to the way that source datasets were combined. This is because many species show large inter-annual variability in cover and ecological impacts, and are able to seed-bank for several years...
This data set contains elevation data and shows potential suitable precipitation ranges for Houndstongue in the Middle Rockies Ecoregion.
This data set contains potential threat based on proximity to electrical transmission lines and cellular and wind turbine towers for the Greater Sage-Grouse in the Middle Rockies Ecoregion. This data set contains categorical values based on distances away from transmission lines and towers.
This data set contains a weighted sum of bioclimatic factors for Hoary Cress. Input layers included; suitable precipitation, suitable elevation, suitable soils, suitable vegetation types, suitable temperatures, and roads. Input layers were equally weighted.
This dataset contains RegCM3 Climate Change modeled April snow water equivalent (mm) data for the Middle Rockies Ecoregion (2050-2069).
This dataset shows the current distribution of Rocky Mountain Gambel Oak-Mixed Montane Shrubland extracted from LANDFIRE EVT (v1.1) and NatureServe National Landcover datasets.

This dataset shows the current distribution of Inter-Mountain Basins Mixed Salt Desert Scrub (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...
