The District manages nine permitted wetland and upland preserves at various properties throughout the county. Several preserves are natural and others are man-made mitigation projects for school construction activities. ECS maintains, enhances, and restores regulated sites including removal of exotic and invasive plant species.

Common protected species that are found on District properties are Burrowing Owls and Gopher Tortoises. ECS staff ensures that both of these species are protected in accordance with State and Federal law. It is prohibited to harass, disturb or relocate endangered species without a permit. Other species protected in the State of Florida include Birds of Prey and Bats. Discovery of potentially endangered or protected animals should be reported immediately to ECS for action.
