Bosques de pantano en la zona central de la reserva forestal imataca, Venezuela

Swamp forests are permanently flooded ecosystems, where plants must develop highly 
specialized adaptations that allow their survival in soils with very low aeration. The objective of this work was to characterize the structure, floristic composition and edaphic elements of swamp forests in the central area of the Imataca Forest Reserve, in order to analyze options for their sustainable management. Three square plots of 1 ha were evaluated in primary forests, where all individuals with a diameter greater than 10 cm were measured; in addition, in each plot, undergrowth was evaluated (individuals with diameter less than 10 cm) by four subplots of 10 m x 10 m. These ecosystems are dominated by Catostemma commune, a species that shows high abundance, dominance and regeneration; are also abundant other commercial species such as Carapa guianensis, Protium decandrum and Sterculia pruriens. There is an average of 7 commercial individuals per ha, with a diameter greater than 60 cm; in addition there is a regular diametric structure. Soils are acidic and very poor in nutrients; but aluminum is neutralized by calcium and this is reflected in the fact that this forest has the largest basal area of the whole sector (32.3 m2 ha-1). It is concluded that a possible harvest in these swamps deserves reduced impact techniques, and it would be advisable to test agroforestry systems that can improve the living conditions of the natives who live in the surroundings.
