Attachment A – Apollo Beach Pre-Post Site Conditions & Plan
The vast majority of pre-construction site was low-quality upland habitat from numerous plant species that
colonized the site in the 47 years since construction of the filled Apollo Beach peninsula. With sterile dredged
soils and minimal seed source of desirable upland species, the “plateau” (average elev. 9-10 ft.) offered little
opportunity for desirable species to colonize. Cogon grass (Imperata brasiliensis) was the most dominant ground
cover species (refer to site photos). Other herbs included purple sedge (Cyperus ligularis), hurricane grass
(Fimbristylis spathacea), licorice weed (Scoparia dulcis), seaside evening primrose (Oenothera humifusa), and
camphor daisy (Haploppus phyllocephalus). Shrub and tree species were present in the form of scattered
individuals and small, dense pockets. Dominant species included Brazilian pepper (Schinus terebinthifolius), saltbush
(Baccharis angustifolia), wax myrtle (Myrica cerifera), lantana (Lantana camara), cabbage palm (Sabal
palmetto), and Australian pine (Casuarina equisetifolia). A narrow strip of intertidal wetland exists along the outer,
waterward edge of the site. Woody vegetation in this zone consists mainly of white mangrove (Lagucularia
racemosa) and black mangrove (Avicennia germains), with scattered Brazilian pepper and coinvine (Dalbergia
castaphyllum). Herbs include sea purslane (Sesuvium portulacastrum), saltmeadow cordgrass (Spartina patens),
and saltwort (Batis maritima).
Several coastal habitats were constructed starting in 2003 and completion in 2004. The open water component
(10.8 acres) includes sub-tidal, mudflats, and salterns created between elevations 0.5 feet to deeper than -2.0
feet. The interconnected deepwater channels provide tidal flows into the interior of the peninsula. Deeper pools
