Title:
Charlotte County Aerial Distribution Survey for Manatees (January 1987 to December 1988)

Description:
Abstract:
Aerial distributional surveys are used by marine mammal biologists from FWC and other agencies to determine the seasonal distribution of manatees. Most surveys are done from small, four-seat, high-winged airplanes (Cessna 172 or 182) flying at a height of 500-1000 ft at a speed of 70-90 kts. Small helicopters may be used instead of fixed wing aircraft in urban areas or where waters are particularly opaque and hovering may be required. Flights are usually 4–6 hours long, and are most commonly flown every two weeks for two years. The surveys are designed to maximize the manatee counts by concentrating on shallow nearshore waters where manatees and their primary food source, seagrasses, are located. Flight paths curve along parallel to the shoreline, and the airplane circles when manatees are spotted until a count of the number of animals in each group is obtained. Offshore waters are usually not surveyed. Dolphin and sea turtle sightings are recorded opportunistically. All aerial data are recorded on paper maps and entered into a GIS shapefile for spatial analysis. GIS is a computer software system for representing data spatially and for conducting spatial analyses. Surveys of Charlotte County were flown twice a month from January 1987 to December 1998. FWC staff members were observers for these flights. The survey areas includes the coastal waters of Charlotte County and small adjacent sections Lee, Sarasota and deSoto Counties. Major water bodies included Charlotte Harbor, Myakka River, Peace River, Bull Bay, Turtle Bay and lower Gasparilla Sound. Many undeveloped areas under state or federal management are part of the study area.
Purpose:
To determine the seasonal distribution of manatees in Charlotte County, FL.
Supplemental_Information:
--Prior to July 1, 2004, the Fish and Wildlife Research Institute (FWRI) was known as the Florida Marine Research Institute (FMRI). The institute name has not been changed in historical data sets or references to work completed by the Florida Marine Research Institute. The institute name has been changed in references to ongoing research, new research, and contact information.--

Completeness_Report:
48 total flights. One survey missed in January 1987, March 1987 and May 1988 due to poor weather conditions and scheduling conflicts. Three surveys were flown in February 1987, April 1987 and June 1988. No manatees were sighted on the following surveys: 1/14/1987, 1/28/1988.

Process_Step:
Process_Description:
After the survey, sightings are assigned a unique ID number, and data are digitized as points into a GIS shapefile. The location of the point and the attribute information are verified after digitization. Sightings were plotted in reference to the FWC-FWRI Wildlife Research Marine Mammal section 40K shoreline. This dataset is subset to only include manatee sightings, though sea turtle and/or dolphin sightings may have been recorded.
