Name: 2007 Seagrass data for Springs Coast Florida
Display Field: COMMON_NAM
Type: Feature Layer
Geometry Type: esriGeometryPolygon
Description: The Southwest Florida Water Management District (District) is responsible for the protection and management of natural systems and water quality within its geographic boundaries. One component of evaluating the ecological health of coastal ecosystems is to map and monitor submerged aquatic vegetation (SAV) communities. This project is a continuation of previous efforts to determine the status and trends (if any) of SAV resources in the coastal waters of the District. The results of this effort will be used to determine the performance of ongoing efforts to improve water quality in coastal waters of the District. This project will complete a detailed map of the selected benthic habitats along the Springs Coast region.

Description: The Southwest Florida Water Management District (SWFWMD) is responsible for the protection and management of natural systems and water quality within its geographic boundaries. One component of evaluating the ecological health of coastal ecosystems is to map and monitor submerged aquatic vegetation (SAV) communities. The area of interest includes the mid-shore coastal waters of the District within Citrus and Hernando counities. Estuaries in the geographic area of interest include the Chassahowitzka River, Homosassa River, and the Weeki Wachee River. The project area includes 1,454 cells (approximately 1,304 square miles) and extends from roughly 5 miles offshore to a maximum of 15 miles offshore. Seagrass data were photointerpreted from one foot resolution RGB 5000 x 5000 foot tiles flown in January 2012 and IKONOS satellite imagery (1mresolution, multispectral).The minimum mapping unit for classification was 0.25 acres.

Description: The Southwest Florida Water Management District (SWFWMD) is responsible for the protection and management of natural systems and water quality within its geographic boundaries. One component of evaluating the ecological health of coastal ecosystems is to map and monitor submerged aquatic vegetation (SAV) communities. The AOI includes the mid-shore coastal waters of the District between Levy County to the north and to Pasco County to the south. Estuaries in the geographic area of interest include the Waccasassa River, Chassahowitzka River, Homosassa River, and the Weeki Wachee River. The project area includes 741 images (approximately 1,310 square miles) and extends from roughly 5 miles offshore to a maximum of 15 miles offshore. For the 2016 effort, the AOI was expanded from the previous 2012 footprint to incorporate complete Florida Department of Environmental Protection WIBIDs. For acreage reporting purposes the, the AOI for 2016 and the previous 2012 footprint were both trimmed to meet the boundary of the St. Joseph Sound and Clearwater Harbor, seagrass mapping extent of the AOI, as it existed in January 2016. Seagrass data were photo interpreted from 2016 Natural Color 4-band multi-spectral digital imagery using a Leica ADS100 sensor (Sensor head 100) operating with an inertial measuring unit (IMU) and a dual frequency GPS receiver. The project area was flown at an altitude of 11,300 feet above mean terrain (AMT). Imagery was acquired in two lifts on 20 January, 2016 and 01 March, 2016. Mapping shall be conducted with a minimum mapping unit of 0.5 acre for all benthic features and Oysters minimum mapping unit of 0.25 acre. Minimum mapping of 0.25 acre is allowable if situation deems appropriate but is not required.

This project is a continuation of previous efforts to determine the status and trends (if any) of SAV resources in the coastal waters of the District. The results of this effort will be used to determine the performance of ongoing efforts to improve water quality and quantity in coastal waters of the District.The dataset serves as documentation of the seagrass habitat within Anclote River, Pithlachascotee River, Aripeka River, Weeki Wachee River, Chassahowitzka River, Homosassa River, Crystal Bay, Withlacoochee River, Waccasassa Bay and their respective offshore areas as it existed in January 2020. Seagrass data were photointerpreted from 2020 1:24,000 scale natural color aerial photography and classified using the SWFWMD modified FLUCCS classification system. Horizontal accuracy of meets NMAS for 1:12,000 scale maps. The minimum mapping unit for classification was 0.25 acres.
