The surface disturbance footprint raster data set quantifies the percent surface disturbance from development at a 90-meter resolution. The surface disturbance footprint is used to compute a multiscale index of landscape intactness for the Bureau of Land Management’s (BLM) landscape approach. The surface disturbance footprint is mapped for the western United States (17 states), by compiling and combining spatial data for four development disturbance variable classes. Development classes include urban land cover (impervious surface), agriculture (cropland), energy and mineral extraction and transport (oil and gas wells, solar arrays, wind turbines, surface mines, pipelines, and transmission lines), and transportation...

The Terrestrial Development Index (TDI) quantifies levels of development (urban, agriculture, energy and mineral extraction and transmission, and transportation). TDI scores represent the total percentage of the development footprint within a 2.5 kilometer (km) radius circular moving window. The TDI scores range from 0-100%. The TDI scores between 0-1% represent areas with few roads or a very low density of oil and gas wells. The TDI scores between 1-3% often include low densities of oil and gas wells and roads, whereas development index scores above 3% represent moderate to high levels of development, including relatively large oil and gas fields, surface mines, agricultural fields, centers of urban development,...

The "Broad-scale assessment of biophysical features in Colorado: Terrestrial development index using 5-kilometer moving window" raster dataset quantifies levels of development (urban, agriculture, energy and mineral extraction and transmission, and roads and railroads) for all lands in Colorado. The terrestrial development index (TDI) represents the total percentage of the estimated surface disturbance footprint from development within a 5-kilometer (km) radius moving window. The TDI scores range from 0 to 100 percent. Methods are described in the companion report (see "Larger Work" section).

Landscape intactness has been defined as a quantifiable estimate of naturalness measured on a gradient of anthropogenic influence. We developed a multiscale index of landscape intactness for the Bureau of Land Management’s (BLM) landscape approach, which requires multiple scales of information to quantify the cumulative effects of land use. The multiscale index of landscape intactness represents a gradient of anthropogenic influence as represented by development levels at two analysis scales. To create the index, we first mapped the surface disturbance footprint of development, for the western U.S., by compiling and combining spatial data for urban development, agriculture, energy and minerals, and transportation...

This data release includes three types of data used in habitat modeling, and predictions from the habitat models. (1) Predictor rasters for proportion urban development within 1-km radius, proportion exurban within 1-km radius, vector ruggedness measure (VRM) within 500-m radius, topographic position index (TPI) within 500-m radius. (2) Twenty-nine null models for space use for 29 different golden eagles. (3) Twenty-nine response variable rasters of eagle locations per cell for 29 golden eagles. (4) A raster for predicted population-level probability of habitat selection and contours for predicted population-level probability of habitat selection and contours. These data support the following publication: Tracey,...
AbstractUrban development is a principal driver of landscape change affecting the integrity of ecological systems and the capacity of the landscape to support species. We developed an urban growth model (SPRAWL), evaluated it with hindcasting, and used it to simulate urban growth across the northeastern United States between 2010 and 2080 under four alternative scenarios. In the model, urban growth is constrained by demand for new development for each time step at the subregional scale. Demand is subsequently allocated to local application panes (5 km on a side within 15 km window) using a unique landscape context matching algorithm, such that the more historical development that occurred in the matched training...
The Terrestrial Development Index (TDI) quantifies the level of development (urban, agriculture, energy and mineral extraction and transmission, and transportation) based on the surface disturbance footprint. TDI values range from 0 to 100% and represent the total percentage of land surface occupied by the development footprint within a 1-kilometer (km) radius moving window.

The “Biophysical assessment for indemnity selection of federal lands in Colorado: Development” dataset quantifies the estimated surface disturbance from development (urban, agriculture, energy and mineral extraction and transmission, and roads and railroads) at several analysis scales for each of 89 Indemnity Units. The Indemnity Units are federal lands, currently managed by the Bureau of Land Management (BLM), under consideration for transfer of ownership to the State of Colorado in compensation for federal lands not available for transfer at the time of statehood. The companion data release (see "Cross Reference" section) was used to summarize the surface disturbance from development (development footprint) at...

Information on the biophysical features of federal lands identified as suitable for transfer to the State of Colorado was requested by the Bureau of Land Management (BLM). This information is intended for use in conducting an environmental assessment prior to transfer of ownership (conveyance) to the State. The Enabling Act of 1864 provided for the conveyance of federal lands to the State for the support of schools. If designated lands were unavailable for transfer at the time of statehood, the Act provided for the transfer of alternative federal lands in compensation, using a process referred to as “school-land indemnity selection.” To initiate indemnity selection, the Colorado State Board of Land Commissioners...

The terrestrial development index (TDI) quantifies levels of development (urban, agriculture, energy and mineral extraction and transmission, and transportation). TDI scores represent the total percentage of the development footprint within a 20-kilometer radius circular moving window. The Surface Disturbance Footprint from Development for the Western United States is used in the moving window analysis. The TDI scores range from 0-100%.

Land managers have incorporated threats to biodiversity for nearly two decades, but very few efforts have included threats from future conditions and fewer still have assessed vulnerability to climate change. This project will address two themes: 1) providing foundational information about habitat fragmentation and connectivity and 2) identifying the degree of vulnerability of key habitats to climate change.For development of understanding broadextent, a landscape-level pattern of climate change is an important complement to approaches to estimate rangeshifts for certain key focal species. Ecological system types (i.e. coarsefilters) are widely used in conservation planning because they contain valuable resources...

Information on ecological communities, soil salinity, and land use was synthesized and summarized for all lands in Colorado. This biophysical information was requested by the Bureau of Land Management (BLM) for use in conducting an environmental assessment prior to the transfer of ownership (conveyance) of federal lands to the State of Colorado. The Enabling Act of 1864 provided for the conveyance of federal lands to the State for the support of schools. If designated lands were unavailable for transfer at the time of statehood in 1875, the Act provided for the transfer of alternative federal lands in compensation, using a process referred to as “school-land indemnity selection.” To initiate indemnity selection,...

Landscape intactness has been defined as a quantifiable estimate of naturalness measured on a gradient of anthropogenic influence and based on available spatial data. We developed a multiscale index of landscape intactness for use as a broad-scale indicator of resource condition for the Bureau of Land Management’s (BLM) Landscape Approach, which requires multiple scales of information to quantify the cumulative effects of land use. The multiscale index of landscape intactness represents a gradient of anthropogenic influence as represented by development levels at two analysis scales. To calculate landscape intactness we combined the terrestrial development index (TDI) summarized at two scales (using a 2.5- and a...
