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...
Accruate mapping of tidal wetlands is vital for effective conservation and restoration of these valued habitats, and good mapping is key to strategic planning for coastal resilience. Tidal wetlands are defined by regular inundation by the tides; therefore, mapping of tidal wetlands should be based on knowledge of tidal water levels and the land areas inundated by the tides. We developed this tidal wetland mapping following that principle. Briefly, we used a method developed in Oregon that combines NOAA’s extreme water level models with high-resolution LIDAR digital elevation models (DEMs) to map areas subject to tidal inundation. We refined the mapping using additional data sources such as the National Wetland...

This point layer represents estuaries present within PMEP’s spatial data system. This layer was developed by members of PMEP, based partly on previous estuary inventory efforts as well asthe goals of PMEP. Currently, there are 444 estuaries present in this layer, covering the West Coast of the contiguous United States. Estuaries were included based on their current or future potential to provide habitat for fish species. It is possible that this list will expand or contract over time, as determined by the needs of PMEP.

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...

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.

Eelgrass is a type of marine, flowering seagrass that grows underwater in temperate marine environments around the world, and on the West coast includes three species: (1) Zostera marina, (2) non-native dwarf eelgrass, Zostera japonica, and (3) a distinct species to Southern California, Zostera pacifica. In 2014, TNC and PMEP produced the report, “Nursey Functions of U.S. West Coast Estuaries: The State of Knowledge for Juveniles of Focal Invertebrate and Fish Species,” which found that eelgrass (Zostera sp.) meadows are one of the most important juvenile habitats for a broad array of fish species. Understanding the spatial extent of eelgrass habitats in West Coast estuaries is important for restoration and conservation...

These data represent the Biotic Component (BC) of the Coastal and Marine Ecological Classification Standard (CMECS) for estuaries of the West Coast of the contiguous United States. The BC is organized into a branched hierarchy of five nested levels: biotic setting, biotic class, biotic subclass, biotic group, and biotic community. Classes and subclasses of the BC are determined by the dominant biota (defined as the most abundant in terms of percent cover) of the substrate. Following the methods developed by the Oregon Coastal Management Program (OCMP) – Oregon Department of Land Conservation and Development (https://www.coastalatlas.net/documents/cmecs/PhaseI/EPSM_CoreGISMethods.pdf), we cross-walked attributes...

The Protected Areas Database of the United States (PAD-US) is a geodatabase that illustrates and describes public land ownership, management and conservation lands nationally, including voluntarily provided privately protected areas. The lands included in PAD-US are assigned conservation measures that qualify their intent to manage lands for the preservation of biological diversity and to other natural, recreational and cultural uses; managed for these purposes through legal or other effective means.
