Project Description
A. Overall project goal: Mobbly Bayou Wilderness Preserve is a 383 acre preserve within one of the few
undeveloped tracts adjacent to Tampa Bay (Figure A). The Preserve has diverse upland and wetland habitats
critical for a wide variety of wildlife species. However, these habitats have been impacted by the construction of
mosquito ditches, ponds and adjacent development. The project goal includes conducting wetland habitat
restoration and enhancement by filling ditches to restore appropriate hydrologic regimes, creation of vital
oligohaline habitat to provide the salinity transition between freshwater and estuarine wetlands, and the
eradication of exotic species. Additional habitat enhancement will be conducted by eradicating Brazilian pepper
within the upland habitat area adjacent to the wetlands.
B. Brief description of current condition: The Preserve's habitats include a dominance of mangrove forests
and salt-marsh, with additional coverage provided by saltern, pine flatwoods, cabbage palm flatwoods, coastal
hammock, and freshwater marsh (refer to Figures B & C). Much of the mangrove forest, salt marsh, and saltern
habitat have been hydrologically altered by the construction of mosquito ditches. The ditches limit appropriate
and adequate tidal range and fluctuation within the estuarine wetlands. In addition, because of diverted storm
and surface water from adjacent developed areas, there is less frequency and consistency of contributing
