This dataset provides information on the current status and various other habitat and descriptive attributes of the native coastal vegetation for seven of the main Hawaiian Islands (i.e., does not include Ni`ihau).

These data depict reptile species richness within the range of the Greater Sage-grouse. Species boundaries were defined as the total extent of a species geographic limits. This raster largely used species range data from "U.S. Geological Survey - Gap Analysis Project Species Range Maps CONUS_2001", however in order for a more complete picture of species richness, additional sources were used for species missing from the Gap Analysis program.

In 2019, dye tracing investigations were conducted near Manitou Cave in Dekalb County, northeast Alabama. The purpose of the dye tracing was to delineate a recharge area for the stream in Manitou Cave, a 1.7-kilometer-long stream cave and the only known habitat for the Manitou Cavesnail (Antroribus breweri). In 2010, the U.S. Fish and Wildlife Service was petitioned by the Center for Biological Diversity to federally list the Manitou Cavesnail. However, before any listing or vulnerability designation can occur, more knowledge was required, specifically regarding potential threats to the snail. With regards to the Manitou Cavesnail, this required delineating a recharge for the stream in Manitou Cave in order to determine...

Fish community richness, density, and biomass for entire communities, Brook Trout, Rainbow Trout, and minnows, including site characteristics, and water chemistry (acid neutralizing capacity, pH, nitrate, sulfate, ammonia, calcium, and total aluminum) collected at least once and as many as 13 times at each of 52 stream sites during the same years that fish were inventoried, Great Smoky Mountains National Park, 1993-2014.

This habitat model was developed to identify suitable habitat for the federally-endangered least Bell’s vireo (Vireo bellii pusillus) across its current and historic range in California. The vireo disappeared from most of its range by the 1980s, remaining only in small populations in southern California. Habitat protection and management since the mid-1980s has led to an increase in southern California vireo populations with small numbers of birds recently expanding into the historic range. Predictions from this model will be used to focus surveys in the historic range to determine where vireos are recolonizing and to track the status and distribution of populations over time. We used the Partitioned Mahalanobis...
