Uplands comprise any land area not defined as wetlands or surface waters, including all native upland habitat and impacted lands such as pasture and other cleared areas. Twenty-five percent of the native upland habitat found on a site being developed must be preserved. A Preserve Area Management Plan (PAMP) will be required as part of any development approval. An environmental consultant can provide information on upland preservation and can prepare a PAMP for submittal to the County.
The Martin County Comprehensive Growth Management Plan has adopted the definition of wetlands found in Florida Statutes.
This definition states that wetlands are "... those areas that are inundated or saturated by surface water or groundwater at a frequency and a duration sufficient to support, and under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soils. Soils present in wetlands are generally classified as hydric or alluvial, or possess characteristics that are associated with reducing soil conditions. The prevalent vegetation in wetlands generally consists of facultative or obligate hydrophytic macrophytes that are typically adapted to areas having soil conditions described above.
These species, due to morphological, physiological, or reproductive adaptations, have the ability to grow, reproduce, or persist in aquatic environments or anaerobic soil conditions. Florida wetlands generally include swamps, marshes, bayheads, bogs, cypress domes and strands, sloughs, wet prairies, riverine swamps and marshes, hydric seepage slopes, tidal marshes, mangrove swamps and other similar areas. Florida wetlands generally do not include longleaf or slash pine flatwoods with an understory dominated by saw palmetto."
