Prescribed fire and selected timbering have reduced the canopy cover.Longleaf pine and threeawn will be replanted where appropriate. • A comprehensive monitoringprogram is in place. Prescribed burning is used in all fire-dependent habitats. • Exotic plants, mostlyBrazilian pepper and cogongrass, are actively controlled. • The Management Plan is revised everyfive years, and both sites are managed by DEP. • Hunting is prohibited and logging is solely forrestoration purposes. • A few groups of Florida Scrub-Jays occur in recently-purchased scrub just
