I.A.5.N.c. Seasonally flooded tropical or subtropical broad-leaved evergreen sclerophyllous forest

A.75 Rhizophora mangle - Conocarpus erectus Seasonally Flooded Forest Alliance


Red Mangrove - Buttonwood Seasonally Flooded Forest Alliance

Alliance Concept

Summary: This alliance consists of short, non-tidal mangrove forests on seasonally flooded peats in island interior depressions of the Florida Keys and southern peninsular Florida. These communities are often referred to as basin mangrove communities. The mangrove canopy is usually 3-12 m high, closed, and consists of a variable mixture of Rhizophora mangle, Avicennia germinans, Laguncularia racemosa, and Conocarpus erectus. Ficus aurea may be present, as well. The subcanopy and shrub strata can be well-developed, and in some associations include species such as Jacquinia keyensis, Sideroxylon celastrinum, Lycium carolinianum, Rhabdadenia biflora, and Batis maritima. Herbs can include Cladium mariscus ssp. jamaicense, Ipomoea violacea, and Acrostichum spp. Epiphytes in some associations are abundant and diverse, and include Tillandsia flexuosa, Tillandsia paucifolia, Tillandsia fasciculata, Tillandsia balbisiana, Tillandsia X smalliana, Tillandsia utriculata, Encyclia tampensis, and Vanilla barbellata.
