| description:

Aerial distribution surveys are used by marine mammal biologists from FWC and other agencies to determine the seasonal distribution of manatees. Most surveys are conducted 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 five 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 around the state where manatees and their primary food source, sea grasses, are located. Flight paths curve 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 Collier County (Marco Island) were flown twice a month from January 1989 to December 1990. FWC staff members were observers for these flights. The survey area includes most coastal waters surrounding Marco Island in west-central Collier County. Major bodies of water include Rookery Bay, Henderson Creek, Little Marco Pass, Johnson Bay, Collier Bay, Big Marco Pass, Tarpon Bay, McIlvane Bay, Addison Bay, Roberts Bay, Caxambas, Bay, and Caxambas Pass. Parts of Rookery Bay Wildlife Preserve and Rookery Bay National Estuarine Research Reserve were included in the survey. |
