Prior research has shown that sediment budgets, and therefore stability, of microtidal marsh complexes scale with areal unvegetated to vegetated marsh ratios (UVVR) suggesting these metrics are broadly applicable indicators of microtidal marsh vulnerability. This effort has developed the UVVR metric using Landsat 8 satellite imagery for the coastal areas of the contiguous United States (CONUS). These datasets provide annual averages of 1) developed, 2) vegetated, 3) unvegetated fractional covers and 4) an unvegetated to vegetated ratio (UVVR) at 30-meter resolution over the coastal areas of the contiguous United States for the years 2014-2018. Additionally, multi-year average values of vegetated fractional cover...

The U.S. Geological Survey (USGS) calculated multiple basin characteristics as part of preparing the Upper Colorado & Gunnison Rivers Pilot StreamStats application. These datasets are raster representations of various environmental, geological, and land use attributes within the Upper Colorado & Gunnison Rivers study area (also known as the Next-Generation Water Observing System, or NGWOS), and will be served in the National StreamStats application (https://streamstats.usgs.gov) to describe delineated watersheds. The StreamStats application provides access to spatial analysis tools that are useful for water-resources planning and management, and for engineering and design purposes. The map-based user interface can...

Density (km / km^2) of all roads in the western United States. Dataset was developed to generalize the 2000 US Census TIGER/Line Roads layer to a density within 18km of each pixel. Obtained from 2000 US Census TIGER/Line Roads using LINEDENSITY with an 18km search radius.
This is a map of populated areas with population density greater than or equal to 1 individual/ha (i.e., rural/exurban but including suburban and urban as defined by Marzluff et al. 2001) as determined from U.S. Census data corrected for public lands.

Future county population was based on projections for 2100 from the Spatially Explicit Regional Growth Model (SERGoM; Theobald 2005). SERGoM simulates population based on existing patterns of growth by census block, groundwater well and road density, and transportation distance to urban areas, while constraining the pattern of development to areas outside of protected areas and urban areas (Theobald 2005). The dataset here is a projection for a “baseline” growth scenario that assumes a similar trajectory to that of current urban growth (Bierwagen et al. 2010). SERGoM accuracy is estimated as 79–99% when compared to 1990 and 2000 census data, with the accuracy varying by urban/exurban/rural categories and increasing...

We evaluated the fragmentation of the western United States by anthropogenic features. The addition of roads, railroads, and power lines to wildlands, and the conversion of wildlands to agricultural land and/or urban areas, induces fragmentation. We used the following spatial data sets to model anthropogenic fragmentation: agricultural land, populated areas, power lines, railroads, and roads. Because we were interested in the spatial arrangements of wildland patches and how anthropogenic fragmentation affects wildlife dispersal, we buffered some of these spatial data sets according to their area of influence. For example, the area of influence of interstate highways extends beyond the traffic lanes (Rowland et al....

We calculated the intensity of recreation visitation in 2014 based on Forest Service (FS) visits reported in the National Visitor Use Monitoring System at the level of a National Forest (English et. al., 2002). Recreation use on FS lands is tracked at five-year intervals (2010–2014), therefore these data represent a rough estimate of potential 2014 visits. English, D. B. K., S. M. Kocis, S. J. Zarnoch, and J. R. Arnold. 2002. Forest service national visitor use monitoring process: research method documentation. Gen. Tech. Rep. SRS-57.
