Take a journey through one of the largest eelgrass meadow in the lower 48 (8000+ acres). The PBNERR Sentinel Site Story Map provides a tour of the Sentinel Site infrastructure under development to monitor impacts of climate change and changes in sea level on the eelgrasses of Padilla Bay.

Habitat Maps

Habitat map of intertidal vegetation. Links to full report

Habitat maps of intertidal vegetation (2 species of eelgrass, green algae, and salt marsh) in 2 categories of percent cover have been produced for the entire bay from 1989, 2000, and 2004 imagery. Images were interpreted using on-screen delineation and ground truth data based on the NOAA Coastal Services Center’s 2001 publication “Guidance for Benthic Habitat Mapping: An Aerial Photographic Approach”. The 2004 habitat map conforms to the Mapping Land Use and Habitat Change in the NERRS: Revised Standard Operating Procedures including an accuracy assessment matrix table. Download final report (PDF, 2.4 MB).

The original habitat classes have been reclassified to match the “Habitat and Land Cover Classification Scheme for the National Estuarine Research Reserve System” published in 2008 and clipped to the reserve boundary (available as a zipped shapefile download from the CDMO website). The data has also been cross-walked to the new Federal Coastal and Marine Ecological Classification Standard (CMECS). The Crosswalk Tool is available from NOAA OCM Digitalcoast. The 2004 habitat map can be accessed by the public for online mapping and/or download as an ArcGIS Online Feature Service and web map.
