Abstract

Species monitoring, population assessments, and behavioral observations of many endangered marine mammals are typically limited to surveys of animal surfacings due to the challenges of detecting and tracking individuals that usually live in remote areas. This study demonstrates the benefits of using unmanned aerial vehicles (UAVs), or drones, as a noninvasive and low-cost method to monitor and observe Florida manatee (Trichechus manatus latirostris) populations. We conducted several flights using a small multirotor drone to detect manatees in a warm-water refuge area at Round Island Riverside Park in Indian River County, Florida. Through the use of aerial videos, we confirmed three sightings of manatees. These data emphasize the potential of drone surveys to assess abundance and density as well as analyze behavioral ecology in regard to foraging strategies, habitat use, social interactions and herd structure. Using high-resolution images, individuals may be identified based on scar patterns and distinctive markings.
