This ArcGIS Map Package contains information on brook trout occupancy in the southern portion of the brook trout range (PA and south). Fish sample data from a number of state and federal agencies/organizations were used to define patches for brook trout as groups of occupied contiguous catchment polygons from the National Hydrography Dataset Plus Version 1 (NHDPlusV1) catchment GIS layer. After defining patches, NHDPlusV1 catchments were assigned occupancy codes. Then state and federal agencies reviewed patches and codes to verify data accuracy. A similar effort is currently being conducted by the Eastern Brook Trout Joint Venture to develop occupancy data for the remainder of the brook trout range including states...

This shapefile contains cumulative fish habitat condition index (HCI) scores as well as specific disturbance indices for local and network catchments of Southeast Alaska. Catchments were created in support of Jared Ross's Master’s thesis. The source datasets compiled and attributed to spatial units were identified as being: (1) meaningful for assessing fluvial fish habitat; (2) consistent across the entire study area in the way that they were assembled; (3) broadly representative of conditions in the past 10 years, and (4) of sufficient spatial resolution that they could be used to make valid comparisons among local catchment units.

The Regional Estuary Assessment for the northern Gulf of Mexico represents an effort to develop, test, and implement a new assessment methodology for marine habitats that improves the analytical basis for identifying impacts to estuary fish habitats. Building from work completed for the National Estuary Assessment, this approach includes: 1) information on fish and shellfish presence/absence from over 70,000 sampling events collected over two decades, to better relate fish habitat condition to natural and anthropogenic variables; 2) data on natural factors, to better incorporate information on the natural susceptibility of individual estuaries; and 3) regional datasets not available on a nationally-consistent basis....

This spatial data layer provides an indirect estimate of emergent, scrub-shrub and forested tidal wetland losses for 55 non-lagoonal estuaries spanning the contiguous United States West Coast. Losses are defined as those areas that were tidal wetlands prior to European settlement, but are no longer tidal wetlands today. Losses were estimated by comparing the National Wetland Inventory‘s mapping of current tidal wetlands to the Pacific Marine and Estuarine Fish Habitat Partnership (PMEP)’s West Coast Estuary Extent mapping. The estuary extent layer represents the likely historical extent of tidal wetlands, so areas not identified as current tidal wetlands in the National Wetlands Inventory (NWI) are considered...

Conservation rank data for each drainage catchments in the Upper Colorado River Basin. Some smaller catchments were not ranked. Catchments are the drainage area (local watersheds) for each individual stream segment within the 1:100,000 scale National Hydrography Plus Version 1 (NHDPlusV1) dataset. The NHDplus catchments have been ranked (valued) based on the representation of native fish species given the threats to their persistence (i.e., non-native fish species, land use, and habitat fragmentation). The ranking process placed importance on areas with several native species as well as areas important to individual species with restricted distributions and so is not simply a species “hot spot” assessment. Catchments...
This item contains two datasets of SARP Conservation Opportunity Areas (COAs) as determined by the SARP Steering Committee and SARP Coastal Committee. To determine inland COAs, each Member State within the Steering Committee has selected 5 inland HUC 8 basins to be designated as SARP COAs. In addition, the SARP Coastal Committee has designated Coastal COAs.

Conservation priority ranks and threat metrics for each drainage catchment in the Lower Colorado River Basin. Catchments are the drainage area (local watersheds) for each individual stream segment within the 1:100,000 scale National Hydrography Plus Version 1 (NHDPlusV1) dataset. Catchments are assigned conservation priority ranks (C_ConsVal) between 0 - 1 with 1 being the highest priority.
