This dataset was developed as part of the research for a Royal Roads University master's thesis entitled "Assessing the impact of human activities on British Columbia’s estuaries". The work was also published through PLOS One (Robb, 2014). The estuary polygons were created by the Pacific Estuary Conservation Program (PECP). Please see Ryder et al., 2007 for more information on their creation. This dataset includes a subset of the PECP estuary dataset because only those estuary polygons that could be linked to to a unique watershed were considered in the analysis. The attributes for each estuary polygon show the spatial coverage of different human activities within the bounds of the estuary and its upstream watershed....

Wetland Patch Size This layer is one of the South Atlantic LCC indicators in the estuarine ecosystem. It is an index based on the size of estuarine patches. Reason for Selection Larger, better connected wetlands are positively associated with fish (Meynecke et al. 2008), shrimp (Turner 1977), and marsh birds. In particular, seaside sparrow (Benoit and Askins 2002, Rush et al. 2009), saltmarsh sharp-tailed sparrow (Benoit and Askins 2002), and marsh wren (Rush et al. 2009) have been associated with marsh area effects. Other species are expected to be limited based on home range size. In addition, wave attenuation is increased with wetland area (Shepard et al. 2011). Over time, a decrease in patch size will correspond...

Problem Dissolved oxygen (DO) is an important indicator of water quality that until recently has been cost-prohibitive to monitor extensively in both space and time. Continuous water-quality data, particularly in coastal environments with bidirectional tidal flow, is necessary for resource managers to understand the dynamic changes in water quality that occur tidally, daily, seasonally, and during aperiodic events. In the estuaries surrounding Long Island, such events may include wastewater treatment plant failures, harmful algal blooms, and extreme weather. The U.S. Geological Survey (USGS) has extensive experience with continuous water-quality monitoring at fixed locations along the coast that provides valuable...

Coastal wetland ecosystems are expected to migrate landward in response to accelerated sea-level rise. However, due to differences in topography and coastal urbanization extent, estuaries vary in their ability to accommodate wetland migration. The landward movement of wetlands requires suitable conditions, such as a gradual slope and land free of urban development. Urban barriers can constrain migration and result in wetland loss (coastal squeeze). For future-focused conservation planning purposes, there is a pressing need to quantify and compare the potential for wetland landward movement and coastal squeeze. For 41 estuaries in the northern Gulf of Mexico (i.e., the USA gulf coast), we quantified and compared...

The NFHAP Coastal Spatial Framework and Indicator Datasets consist of a geospatial base layer developed in ArcGIS, and associated data fields joined to the spatial framework. The Coastal Spatial Framework is a layer of 612 distinct polygons covering coastal areas of the Continental U.S. Polygons represent either coastal watersheds (land) or coastal waters (estuaries, inshore marine, offshore marine),and are classified into six regions and 22 nested subregions. Each polygon is assigned a unique code (UniqueID) to provide location reference for indicator data, and enable joins to separate data tables.s for information recorded in the Bibliography and Assessment tables. Key indicator data fields attributed to each...

Coastal Condition (Estuarine Marsh) This layer is an older version of one of the South Atlantic LCC indicators in the estuarine ecosystem. It is an index of coastal condition capturing water quality, sediment quality, and benthic community condition. This indicator was updated with more current data in Blueprint 2.1 and is delivered in combination with the estuarine open water portion of coastal condition. Reason for Selection This index measures the overall abiotic condition of the system, is well monitored, and is synthesized by the Environmental Protection Agency (EPA) every five years. It integrates measures of water quality, sediment quality, and benthic habitat quality. Input Data The EPA Coastal Condition...

Water-Vegetation Edge This layer is one of the South Atlantic LCC indicators in the estuarine ecosystem. It is an index capturing the length of the edge between open water and estuarine vegetation. Reason for Selection The density and abundance of shrimp, crab, fish, and other nekton are strongly correlated with the open water-vegetation edges (Minello et al. 2003). In a review of nekton species and coastal habitats, open water-vegetation edge was cited as having the second most dense nekton populations (i.e., first being submerged aquatic vegetation, or SAV) (Minello et al. 2003). In particular, the first 1 m of open water near wetlands is often noted as having the highest density of nekton (Minello and Rozas...
