DOWNLOAD EBOOK →Florida Scrub on military installations supports a number of land uses including the Department of Defense (DoD) training and testing mission and threatened, endangered, and sensitive species (TES) conservation. This report documents strategies to manage TES and their habitat on a plant community basis, using methods that apply to multiple species occurring in scrub within the state of Florida. This report provides ecological descriptions of the community, along with available information about community occurrence on DoD installations in Florida. Known occurrences of plant and animal TES are also included. Known and potential impacts to the integrity of the community as TES habitat and to associated species are reported. Impacts are related to habitat fragmentation, and changes in community composition, structure and function due altered fire regime, hydrologic patterns, groundcover integrity or the invasion of exotic species. Management recommendations are made within as ecosystem based, adaptive management context.

DOWNLOAD EBOOK →The Florida Scrub-Jay (Aphelocoma coerulescens) is an indicator of ecosystem integrity of Florida scrub, an endangered ecosystem that requires frequent fire. One of the largest populations of this federally threatened species occurs on John F. Kennedy Space Center/Merritt Island National Wildlife Refuge. Population trends were predicted using population modeling and field data on reproduction and survival of Florida Scrub-Jays collected from 1988 - 1995. Analyses of historical photography indicated that habitat suitability has been declining for 30 years. Field data and computer simulations suggested that the population declined by at least 40% and will decline by another 40% in 1 0 years, if habitat management is not greatly intensified. Data and computer simulations suggest that habitat suitability cannot deviate greatly from optimal for the jay population to persist. Landscape trajectories of vegetation structure, responsible for declining habitat suitability, are associated with the disruption of natural fire regimes. Prescribed fire alone can not reverse the trajectories. A recovery strategy was developed, based on studies of Florida Scrub-Jays and scrub vegetation. A reserve design was formulated based on conservation science principles for scrub ecosystems. The strategy emphasizes frequent fire to restore habitat, but includes mechanical tree cutting for severely degraded areas. Pine thinning across large areas can produce rapid increases in habitat quality. Site-specific strategies will need to be developed, monitored, and modified to achieve conditions suitable for population persistence. Breininger, D. R. and Larson, V.

A classification and regression tree analysis of survey data allowed us to create recommendation for ONF forest managers. We recommend that clear-cut stands should be within 540 meters of other suitable stands. If stands exceed this distance, they should be greater than 26 hectares in size. As edge:area ratio negatively affects occupancy, creating stands with small edge:area ratios (large core space) may positively FLSJ occupancy. As ONF is home to the largest remaining population of this federally threatened species, effective management this habitat is essential to the species persistence. We believe the findings of this study may help forest managers more effectively manage FLSJs in this ecosystem.
Florida Scrub-jay (Aphelocoma Coerulescens) Population Changes at Jonathan Dickinson State Park

DOWNLOAD EBOOK →Each June, surveys are conducted at Jonathan Dickinson State Park in order to monitor the population status of the Florida Scrub-Jay (Aphelocoma coerulescens), the only avian species endemic to the state of Florida. These birds are limited to the rare oak scrub community, a habitat that is under constant threat due to human development. Florida Scrub-Jays are listed as a threatened species under the Endangered Species Act and all of Florida’s populations are in decline. Jonathan Dickinson State Park organizes surveys that collect vital information about the species to better understand how to conserve the fire-dependent oak scrub that they inhabit. The results of this study indicate that efforts to restore the scrub habitat through prescribed burning have been successful at JDSP since the population of Florida Scrub-Jays has stabilized and the birds have dispersed into new areas of the park.
