  • This core topic page is intended to capture bioenergetic dynamics of beaches, particularly primary production and detrital food webs that produce forage and sustainance for birds, fish, and other biota that we manage.
  • The biota and thus food webs found on beaches are defined by elevations zones related to tides. These Tidal Data are gathered and analyzed by the NOAA National Ocean Service.
  • As an ecotone between aquatic and terrestrial habitats, beaches have a high biodiversity.
  • Substrate, salinity and elevation strongly define biota. Dethier 1990 provides a classification of coastal habitats including beaches and their typical biological composition.
  • The relative importance of the primary production provided by Eelgrass and Macroalgae also differs based on sub-tidal sediment texture.
