This dataset provides the results of an assessment of estuary habitat condition in the conterminous United States. To analyze estuary condition, a cumulative disturbance index was developed based on habitat stressor variable data available at a national scale for anthropogenic disturbances measured within estuaries and their associated watersheds. Twenty-eight variables were combined within stressor categories to develop four sub-indices of disturbance for land use, alterations of river flows, pollution sources, and estuary eutrophication. These four sub-indices of disturbance were then combined to develop cumulative disturbance index scores for each estuary. This index describes the estimated combined stress on...

This thematic map illustrates the median value of houses in the United States in 2010. The 2010 median home value is an estimate of home value based on total owner occupied units. This data variable is included in Esri's Updated Demographics (2010/2015). This map shows Esri's 2010 estimates using Census 2000 geographies. The map is designed to be displayed with a 30–50 percent semi-transparency for overlay on other basemaps as noted in the map legend. A basemap with relatively few colors, such as Terrain, This thematic map illustrates the median value of houses in the United States in 2010. The 2010 median home value is an estimate of home value based on total owner occupied units. This data variable is included...

This map service is an information surface which displays whether a soil map unit has no hydric components, some hydric components, or if all the components in a soil map unit are hydric. Each soil map unit polygon falls into one of the following classes according to NRCS: All hydric, Partially hydric, Not hydric, and Unknown. Esri is providing NRCS SSURGO content here without modification except for some cartography and publishing necessary to facilitate esri user access to these data. Of course, esri will continue to update this information as new editions of the SSURGO dataset are published by NRCS. This map service is a representation of the NRCS SSURGO data table MUAGGATT, field HYDCLPRS. The map service...

This shapefile contains landscape factors representing human disturbances summarized to local and network catchments of river reaches for the state of South Dakota. This dataset is the result of clipping the feature class 'NFHAP 2010 HCI Scores and Human Disturbance Data for the Conterminous United States linked to NHDPLUSV1.gdb' to the state boundary of South Dakota. Landscape factors include land uses, population density, roads, dams, mines, and point-source pollution sites. The source datasets that were compiled and attributed to catchments were identified as being: (1) meaningful for assessing fish habitat; (2) consistent across the entire study area in the way that they were assembled; (3) representative of...
What are current conditions for important park natural resources? What are the critical data and knowledge gaps? What are some of the factors that are influencing park resource conditions? Natural Resource Condition Assessments (NRCAs) evaluate and report on the above for a subset of important natural resources in national park units (hereafter, parks). Focal study resources and indicators are selected on a park-by-park basis, guided by use of structured resource assessment and reporting frameworks. Considerations include park resource setting and enabling legislation (what are this park's most important natural resources?) and presently available data and expertise (what can be evaluated at this time?). In addition...

This dataset is the result of clipping the feature class 'NFHAP 2010 HCI Scores and Human Disturbance Data for the Conterminous United States linked to NHDPLUSV1.gdb' to the state boundary of Louisiana. Landscape factors include land uses, population density, roads, dams, mines, and point-source pollution sites.

GAP distribution models represent the areas where species are predicted to occur based on habitat associations. GAP distribution models are the spatial arrangement of environments suitable for occupation by a species. In other words, a species distribution is created using a deductive model to predict areas suitable for occupation within a species range. To represent these suitable environments, GAP compiled existing GAP data, where available, and compiled additional data where needed. Existing data sources were the Southwest Regional Gap Analysis Project (SWReGAP) and the Southeast Gap Analysis Project (SEGAP) as well as a data compiled by Sanborn Solutions and Mason, Bruce and Girard. Habitat associations were...

This shapefile contains landscape factors representing human disturbances summarized to local and network catchments of river reaches for the Desert Fish Habitat Partnership. This dataset is the result of clipping the feature class 'NFHAP 2010 HCI Scores and Human Disturbance Data for the Conterminous United States linked to NHDPLUSV1.gdb' to the boundary of the Desert Fish Habitat Partnership. Landscape factors include land uses, population density, roads, dams, mines, and point-source pollution sites. The source datasets that were compiled and attributed to catchments were identified as being: (1) meaningful for assessing fish habitat; (2) consistent across the entire study area in the way that they were assembled;...

This shapefile contains sub-indices comprised of various anthropogenic land use/covers respresentative of the risk of potential habitat degradation to streams within the state of Hawaii. This file is an updated version of 'nfhap_hci_hawaii.shp' and incorporates the suggestion from the Hawaii Fish Habitat Partnership of removing trails and paths from the road network to help better represent amounts of disturbance in remote areas such as the Na Pali coast. Subindices are summarized for local and network catchments specific to perennial stream reaches throughout the state. The local and network catchments were developed using a modified version of the 1:24,000 scale National Hydrography Dataset (NHD) as a baselayer....

General land manager description (e.g. Federal, Tribal, State, Private) standardized for the US. See PAD-US Data Standard for "Agency Name" to "Agency Type" crosswalk or look up table included in data download, for full domain descriptions. Use "Manager Type" rather than "Owner Type" for the most complete depiction of federal lands as overlapping designations (i.e. "Designation") and ownership related data gaps (i.e. "Unknown") occur in the federal theme.

The Species Richness Maps included here are based on the Gap Analysis Project (GAP) habitat maps, which are predictions of the spatial distribution of suitable environmental and land cover conditions within the United States for individual species. Individual species habitat distribution models were summed to create the total richness for each vertebrate taxa. The summing process was coded in Python 2.7 and employed the arcpy module for geoprocessing steps. The code is documented in the log file which is included in the Sciencebase item along with the richness data for each taxa (See processing steps for file names and sciencebase urls). Mapped habitat distribution areas represent places where the environment is...

This map shows the current distribution of major invasive vegetation species (primarily cheatgrass and tamarisk), and predicted near-term future distribution of these species. Current distribution was derived from LANDFIRE EVT v1.1, NatureServe National Landcover v2.7, Early Season Invasives (USGS), Predicted Tamarisk Probability (USGS), and mapped areas of tamarisk. Predicted future distribution included these areas in addition to the invasive vegetation class from the LANDFIRE Succession Class v1.0 dataset.
