BLM REA SLV 2013 SWReGAP habitat model for the PLAINS LEOPARD FROG Mapping of terrestrial vertebrates focuses on linking a spatial representation of species-habitat matrices to geographic distribution. Each model is a combination of distribution from regional and state references in association with contiguous appropriate habitats. Ranges for all species were based on 8-digit HUCs. Habitats were based on a raster SWReGAP 1 acre MMU land cover data set, with hydrology habitats added in from USGS NHD dataset directly or through modeling. Habitat association information was obtained from various state, regional, and national references with updates from scientific literature. This portion of the Southwest Regional Gap Analysis Project produced predicted habitat distribution maps for...

The dataset uses, in part, the soil data viewer extension for ArcMap to query various soil attributes. Output datasets were then queried for specific thresholds and combined into a composite soils with potential for erosion dataset. There were ten input parameters for the model based on SSURGO/STATSGO soil properties: Available water capacity (=63), electrical conductivity (> 16 dS/m), Sodium adsorption ration (=13), calcium carbonate (>5%), Depth to any soil restrictive layer ( 0.4), slope (>45%),...

One important model developed for the Landscape Assessment to assist in the evaluation of Conservation Element status and trends is the Landscape Intactness Model (LIM). This model builds on a growing body of existing composite scoring methods that aim to characterize the relative ecological condition of landscapes. This model uses indicators of human modification to provide a measurable way to characterize intactness. Indicators and their scores were selected for the Landscape Intactness Model based upon knowledge of their amount and distribution in the study area and understood level of impact to natural systems.

Foraging Areas are defined as areas where Great Blue Herons are known to feed. Appropriate habitat includes shallow water areas associated with reservoirs, lakes, ponds, streams, and backwater areas of major rivers with abundant fish populations. On large irrigation reservoirs, these areas will fluctuate with changing water levels. This information was derived from field personnel. A variety of data capture techniques were used including drawing on mylar overlays at 1:50,000 scale USGS county mapsheets and implementation of the SmartBoard Interactive Whiteboard using stand-up, real-time digitizing...

This data set contains available boundaries and associated attributes for Important Bird Areas (IBAs) in the United States, identified as of May 2013. The IBA boundaries should not be perceived as absolute, definite boundaries. Rather, the boundaries should be considered approximates of the critical habitat areas. Comprehensive site specific surveys have not been conducted for each IBA, therefore, the data provided in this release cannot be relied on as a definitive statement of the presence or absence of all species at a given location.
