Using field sign and necropsy (animal version of autopsy), researchers were able to investigate causes of mortality. Deer were then released at the capture site.ĭuring the study, GPS collars provided over 590,000 deer locations, which was key to understanding survival rates, causes of mortality, and habitat use. Researchers fitted each deer with a GPS collar, attached ear tags, measured and evaluated body weight and condition. Over three capture seasons (winter 2015, 20), 294 deer were captured of which 263 adult deer (172 females, 91 males) were fitted with Global Position System (GPS) collars to monitor their survival and learn how they use various habitats in the south Florida landscape.ĭeer were captured using three different methods: net-gunning from helicopters, rocket netting, and darting from tree stands. Researchers collect data from a captured deer (top) and then safely release it (bottom). While these surveys work well in some areas, they are problematic in areas with thick habitat cover and only provide trend data rather than a precise population estimate. In addition, a cost-effective and reliable way to monitor deer densities was needed. Reliable population density estimates are essential for science-based management in this dynamic region of Florida but are difficult to obtain. In this region, aerial surveys have been the most common method to estimate deer abundance. The area has changed significantly since then, including changes in hydrology, panther abundance, and the broader predator community. Therefore, up-to-date information on survival, causes of mortality and population trends was needed to make effective management decisions. Previous deer research in the Big Cypress National Preserve region occurred in the early 1990s. The South Florida Deer Research Project was initiated in part due to concerns voiced by hunters and agency managers over declining deer populations as well as the need for updated information for management purposes.Īlthough white-tailed deer are one of the most well-studied wildlife species, information about deer in south Florida was limited. In recent years, particularly in the southern portion of the Big Cypress National Preserve and Everglades National Park, the area has experienced deer population declines. Although these declines have coincided with changes in hydrology, habitat and predators, the extent to which these variables have affected the deer population was unknown. In south Florida, deer also are the most important prey species of the Florida panther. Throughout the state, white-tailed deer are one of the most valued and sought-after game species. Research sites consisted of the Florida Panther National Wildlife Refuge (FPNWR), the Bear Island Unit of the Big Cypress National Preserve (BCNP), and a northern section of the Addition Unit of BCNP, commonly referred to as the North Addition Land.įor more information, please see the South Florida Deer Study Final Report. The project ran from 2014 through the end of 2018 and involved four years of intensive field work. Another goal was to develop a monitoring technique to provide reliable estimates of deer densities in south Florida habitats. Fish and Wildlife Service, and National Park Service to gain a better understanding of how water levels, habitat differences, predation and hunting impact deer populations in south Florida. The Florida Fish and Wildlife Conservation Commission partnered with University of Georgia, Virginia Tech, Jones Center at Ichauway, U.S. The South Florida Deer Research Project, one of the largest white-tailed deer studies conducted in the country, is now complete.
