These are extremely sensitive habitats that provide a tremendous benefit. They provide a sheltered habitat, which is used as a breeding and nursery ground for many marine organisms, including fish and invertebrates. In addition, they absorb large quantities of water and protect surrounding areas from flooding and erosion. This translates into loss of habitat for endangered species and an unhealthy ecosystem. Overuse includes filling for development as well as trails unintentionally created throughout these sensitive habitats.
Trails break up native plant aggregations.
Both make a less desirable home for endangered species. The Dog Beach salt marsh is an excellent example. In a recent assessment, the Regional Water Quality Control Board has found significant levels of bacteria. Awareness into Action Wetland Avengers educates the community about the value of this resource and creates a venue in which awareness is directed towards immediate action. Participants work on restoration and clean-up of the area.
