![]() The primary source of parent material for these soils is sand of mixed terrestrial and biogenic origin. In addition, proximity to the lagoon systems influences soil salinity. Relatively small elevation changes cause substantial differences in the position of the water table that, in turn, affect leaching, accumulation of organic matter, and formation of soil horizons. Topography has a dramatic effect on soil formation. 1980) with 58 soil series and land types represented. The soil pattern of Merritt Island-Cape Canaveral is complex ( Huckle et al. The western portion of Merritt Island is substantially older than the east ( Brooks 1972, Clapp 1987). ![]() Multiple dune ridges apparently represent successive stages in this growth. Merritt Island also formed as a prograding barrier island complex, earlier than Cape Canaveral ( White 1958, 1970). Cape Canaveral is part of a prograding barrier island complex ( White 1958, 1970) with alternating periods of deposition and erosion ( Chaki 1974). It is considered Holocene in age, with its formation beginning about 7,000 yr ago ( Brooks 1972, 1981). The outer barrier island and Cape Canaveral formed after sea levels rose when the Wisconsinan glaciers retreated ( Davis 1997). The alternating high and low sea stands of the Pleistocene and Holocene shaped the surface of the region. Surface strata are primarily unconsolidated white to brown quartz sand containing beds of sandy coquina of Pleistocene and Holocene age ( Cooke 1945, Brown et al. The geology beneath CANA consists of a limestone plateau of Eocene age overlain by Miocene clays, phosphatic limestone, and phosphorite, and unconsolidated beds of fine sand, shells, and clay of late Miocene or Pliocene age. The temperate and subtropical plants within CANA are sensitive to climatic changes its coastal location and low elevation makes it vulnerable to sea level rise.įlorida has a complex geologic history ( Randazzo 1997, Scott 1997). Fire management, control of exotics, and restoration of disturbed areas are management concerns. Feral pigs, introduced insects, and plant disease threaten some plants. Twenty Category I and 11 Category II invasive exotic plants (Florida Exotic Pest Plant Council) occur. Five plants are listed in Florida as commercially exploited: Encyclia tampensis, Epidendrum conopseum, Osmunda cinnamomea, O. Plants listed as threatened in Florida include Myrcianthes fragrans, Opuntia stricta, Pteroglossaspis ecristata, and Scaevola plumieri. floridana, Lechea divaricata, Nemastylis floridana, Ophioglossum palmatum, Tephrosia angustissima var. Those listed as endangered in Florida include Argusia gnaphalodes, Chamaesyce cumulicola, Glandularia maritima, Harrisia fragrans, Lantana depressa var. Fifteen taxa considered endangered or threatened by the state of Florida occur one ( Harrisia fragrans) is listed as endangered by the United States Fish and Wildlife Service. Only 40 taxa were not represented by new collections. Of this total, 584 are native and 94 are introduced. The final floristic list includes 679 taxa. We surveyed the flora in 20 terrestrial sites and one lagoon site between the fall of 2002 and the fall of 2004, made additional collections from 2005 to 2015, and examined existing collections in the CANA and KSC (Kennedy Space Center) herbaria annotating them where necessary. 23,335 ha of land, shallow lagoons, and offshore waters in east central Florida.
