Pinellas County has designated an aquatic zone at the southern tip of the county as the Fort Desoto Wetlands and Aquatic Habitat Management Area. This aquatic zone has abundant meadows of seagrasses and is used extensively by recreational boaters and fishermen. Due to the number of boats that use the area there has been considerable damage done to the seagrasses by boat propellers. A monitoring period was established for a minimum of a 5 year period to determine the success or failure of the adopted restrictions. During this period aerial photography was performed on a quarterly basis for purpose of seagrass mapping. Digitization and photointerpretation of the aerials was performed to determine revegetation rates, additional damage or variations in seagrass communities.
