Among the most important habitats in Florida's estuarine environments, seagrass beds are indispensable for the role they play in cycling nutrients, supplying food for wildlife, stabilizing sediments, and providing habitat for juvenile and adult finfish and shellfish. Use the interactive map below to observe the size, density and location of seagrass beds from year to year. The graph shows how the total amount of seagrass in the bay has changed over time.

    Artificial Reefs

    Artificial reefs are created by the placing steel and concrete in carefully selected locations. Once the structure is established, tiny free-floating creatures attach, grow, and quickly attract larger marine life and fish. These lush natural-looking reefs replace lost habitats while creating recreational opportunities for fishing and diving. Learn more about artificial reefs »

      Shoreline Morphology

      The Sarasota Bay study area is highly urbanized. Since the early 1900s, dredge and fill activities and various shoreline hardening projects have resulted in significant losses of ecologically important habitats. This information was gathered as part of a study to assess restoration opportunities in the Sarasota Bay Estuary Program (SBEP) watershed.

        Vegetation Sampling

        Vegetation sampling is the identification and quantification of plant species and communities. Vegetation sampling is a tool used in environmental assessments and can inform a myriad of assessment goals including biomass availability, water quality concerns, management benchmarks, and determining the introduction and establishment of invasive species. Sampling can be conducted via destructive or non-destructive methods. Learn more about vegetation sampling from the links and documents listed below.
