Gulf of Mexico Habitat and Species Vulnerability The Gulf Coast Vulnerability Assessment utilized expert opinion that was gathered through the Standardized Index of Vulnerability and Value (SIVVA) tool, which is an Excel-based vulnerability and prioritization tool that enables assessors to provide input in a relatively short time and allows for relatively seamless compilation of results. The vulnerability of each ecosystem and associated species was conducted by subregion, excluding those subregions where the species did not occur in significant numbers. Assessors were asked to evaluate species based on the habitats they use in a particular subregion. Because vulnerability can vary with life-stage for many species, assessors were asked to consider the most vulnerable...

Data summarize peak abundance (km2) of Central Valley waterbird habitats (i.e., wetland and flooded cropland types) that are available between August and April (of the following year) for each of 17 projected scenarios by planning basin, scenario, and habitat. Area of each habitat for each scenario-basin combination is provided for the month when the most area of the respective habitat is typically flooded and available for waterbird use (i.e., January for all wetlands and winter-flooded rice and corn, and September for other winter-flooded crops in Tulare Basin). The dataset also includes...

The data release was produced in compliance with the new 'open data' requirements as way to make the scientific products associated with USGS research efforts and publications available to the public. The dataset consists of 2 separate items: 1. Vulnerability assessment data for habitat and species based on expert opinion (Tabular datasets) 2.

It is recommended to use Version 2, which can be found at https://doi.org/10.5066/P94C5B06. This CSV file contains cumulative fish habitat condition index (HCI) scores generated for river reaches of the conterminous United States as well as indices generated specifically for four spatial units including local and network catchments and 90 m local and network buffers of river reaches. Note that the cumulative HCI score is determined from limiting index scores generated for the four spatial units listed above. Detailed methods for calculating cumulative fish habitat condition index scores as well as the indices for each spatial extent can be found on the following website:...

The grass/fire cycle is a feedback process between invasive annual grasses and fire frequency that often leads to the formation of alternative vegetation states dominated by the invasive grasses. However, other components of fire regimes, such as burn severity, also have the potential to produce long-term vegetation transformations. Our goal was to evaluate the influence of both fire frequency and burn severity on the transformation of woody-dominated communities to communities dominated by invasive grasses in major elevation zones of the Mojave Desert of western...

Central Valley waterbird habitats investigated in this research included managed flooded wetlands and croplands and dry cropland habitats. Flooded cropland habitats are defined as winter-flooded rice, winter-flooded corn, and other winter-flooded cropland (in Tulare basin). Flooded wetlands are defined as summer-irrigated seasonal wetland, seasonal wetland that is not summer...
