East Panhandle 2019-2023 Manatee Distribution Survey Observations (31)

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. Flight paths curved parallel to the shoreline, and the airplane circled when manatees were spotted until a count of the number of animals in each group was obtained. Circling was limited to 3 passes unless a group was unusually large and aerial photos were used in some cases to confirm counts. Sightings data were recorded on paper maps and entered into a GIS shapefile for spatial analysis using NAIP 2019 imagery and recorded flight paths as a reference. GIS is a computer software system for representing data spatially and for conducting spatial analyses. This dataset includes data from 38 surveys. FWC staff members were primary observers for these flights, and dual observers (two observers, one in the front seat and one in the rear seat) were present on some or all of survey flights. The survey area includes the eastern panhandle of Florida from the Aucilla River to Lake Wimico.
