 es Composición florística, estructura y diversidad del bosque ribereño del Río Kakada, Cuenca del Río Caura, estado Bolívar, Venezuela
Díaz Pérez, Wilmer Antonio; Daza, Félix & Sarmiento, William

Resumen

Se estudiaron los bosques ribereños del río Kakada en su desembocadura en el río Erebato, estado Bolívar, Venezuela, para conocer su composición florística y estructura. Se establecieron seis parcelas de 0,1 ha y se midieron e identificaron todos los individuos con DAP ≥ 10 cm. Los resultados mostraron, para un área acumulativa de 0,6 ha, 36 familias y 61 especies. Las parcelas muestreadas se agruparon en tres tipos de bosque con altura media (16-24 m). La densidad promedio alcanzó a 738 individuos/ha. y área basal promedio de 29,4 m2/ha. De acuerdo a los valores del Índice de Valor Familiar (IVF) las familias más importantes son Fabaceae seguida de Caesalpiniaceae, Chrysobalanaceae, Euphorbiaceae, Sapotaceae, Melastomataceae, Myristicaceae, Clusiaceae, Arecaceae y Mimosaceae. Las especies con mayor importancia en bosques en cubetas o depresiones son Macrolobium acaciifolium check for this species in other resources y Licania pallida check for this species in other resources ; en bosques en bancos y diques se tienen a Eperua jenmanii check for this species in other resources y Licania pallida y en bosques en terrazas y diques a Henriettea succosa check for this species in other resources y Cupania cinerea check for this species in other resources . Se realizó un inventario general donde se reconocieron 48 familias y 97 géneros entre helechos y árboles, arbustos, lianas, epifitas y hierbas de angiospermas representadas por 110 especies. Se presenta una lista de las especies registradas.

Abstract

In order to know their floristic composition and structure, the Kakada river riparian ́s forests in the mouth with the Erebato river, Venezuela, were analyzed. Six 0.1 ha plots were set and all the individuals with DAP ≥ 10 cm were measured and identified. The results indicated, for a cumulative area of 0.6 ha, 36 families and 61 species. The plots were grouped in three types of forests of medium height (16-24 m). The average density was 738 individuals/ha and the basal area was of 29.4 m2/ha. According with the Family Importance Value (FIV) the highest important families are Fabaceae followed by Caesalpiniaceae, Chrysobalanaceae, Euphorbiaceae, Sapotaceae, Melastomataceae, Myristicaceae, Clusiaceae, Arecaceae and Mimosaceae. The IVI ́s most important species in seasonally flooded forests in backswamps or depressions are Macrolobium acaciifolium check for this species in other resources and Licania pallida check for this species in other resources ; in seasonally flooded forests in banks and levees they are Eperua jenmanii check for this species in other resources and Licania pallida and in infrequently flooded forests in terraces and levees Henriettea succosa check for this species in other resources and Cupania cinerea check for this species in other resources . A general floristic inventory was done and 48 families and 97 genera among ferns, trees, shrubs, vines, epiphytes and herbs represented for 110 species were recognized. A list of the collected species is presented.
