General information
Provisional. A provisional ecological site description has undergone quality control and quality assurance review. It contains a working state and transition model and enough information to identify the ecological site.
MLRA notes
Major Land Resource Area (MLRA): 154X–South-Central Florida Ridge
MLRA 154 is entirely in Peninsular Florida, and contains 8,285 square miles. The landscape of MLRA 154 is characterized by a series of parallel, prominent sandy ridges of Pleistocene marine origin, including the Brooksville and Mount Dora Ridges. These North to South oriented parallel ridges are interspersed with more low lying physiographic provinces, including: upland hills, plains, valleys and gaps (Puri and Vernon 1964). The extreme western portion of the MLRA consists of thin belt of coastal lowlands and marshlands.
Many of the soils of MLRA 154 are Pleistocene or Holocene sands that are underlain with older, loamy Pliocene marine sediments (Cypresshead formation) or the clayey Miocene marine sediments (Hawthorne formation). A combination of marine depositional events and the dissolution of underlying limestone (karst geology) is responsible for surficial topography throughout Peninsular Florida.
Classification relationships
All portions of the geographical range of this site falls under the following ecological / land classifications including:
-Environmental Protection Agency’s Level 3 and 4 Ecoregions of Florida: 75 Southern Coastal Plain; 75c Central Florida Ridges and Uplands (Griffith, G. E., Omernik, J. M., & Pierson, S. M., 2013)
-Florida Natural Area Inventory, 2010 Edition: Depression Swamp, Depression Marsh, Basin Swamp (FNAI, 2010)
Ecological site concept
The central concept of the Mineral Depressional Wetlands includes very deep and very poorly drained soils that formed from marine deposits. A few soils are moderately deep to limestone bedrock. These soils occur in isolated depressions or along the fringes of water bodies in flat landscapes (slopes < 1%). This site includes depressional map units of the Allanton, Anclote, Astor, Basinger, Boca, Delray, EauGallie, Felda, Fellowship, Floridana, Floridana Variant, Hicoria, Holopaw, Martel, Monteocha, Myakka, Placid, Pomona, Pompano, Riviera, Sellers, St. Johns, Surrency, Wabasso, and Wesconnett series. This site is mapped in depressions within most physiographic units of this MLRA 154, but is most extensive in the Central Valley, Gulf Coastal Lowlands, and Tsala Apopka Plain. The overall extent is approximately 130,000 acres.
