The Soils of the Intertidal Zone of Rookery Bay, Florida¹

ABSTRACT

The intertidal zone of Rookery Bay, Florida is vegetated primarily with mangrove trees. Mangroves are important to the south Florida fisheries. This work was undertaken to characterize and classify the intertidal soils of Rookery Bay in order to better understand and manage these areas.

Most intertidal soils are classified as Typic Sulfihemists-Typic Sulfaquents. They consist of thin organic deposits over fine sands to sandy clay loam. Spodic Psammaquents also occur at higher elevations. These soils are very poorly drained, saline, and saturated with extractable bases. Most soil samples became more acidic upon drying, probably due to the oxidation of S containing materials. Total S ranged from 0.75% to 1.77% in the sulfidic horizon.
