Tropical Forest (Tropical Moist Forest) (Whitmore, 1990) The rain forest is prevalent over most part of Indonesia. There are considerable floristic variation which are related to differences in soils and topography. Broader variations are also reflected by the horizontal zonation (related to geologic history) Tropical rain forests and vertical zonation (related to elevation) BY: which develop in the hot Tropical seasonal and humid region (every forest which develop in CECEP KUSMANA month is wet, 100 mm seasonally dry climate FACULTY OF FORESTRY, BOGOR AGRICULTURAL rainfall or more) which (4 – 6 dry months with lack of a pronounced dry 60 mm rainfall or less) UNIVERSITY seasons 2011

So, they develop Wader and seabird which nesting, resting and feeding in Fresh water swamp forest are wide spread over alluvial soils pneumatophores in adapting to the anaerobic soils beach forest that are periodically flooded for long periods with rich condition: Sea turtle (green sea turtle, howksbill, leatherback, mineral fresh water (pH more than 6) associated with loggerhead) are nesting in beach forest (Tambelan island, coastal swamp, inland lake and huge low-lying river basin Berau island, Paloh and Lemukuta island at West Kalimantan, Meru Betiri and Baluran NP) Fresh water swamp forest habitat is extremely Coconut Crab (Ocypode) heterogenous in soils and vegetation, where a few centimeters of peat may occur. So that, floristic composition varies from:
