Composition, structure, diversity and increased of forest secondary vegetation in dry tropics, Nandarola, Nicaragua

Abstract

The dry forests of Nicaragua present a diversity of goods and services such as timber species as non-timber species (medicinal, floor protection, wild fauna) and scenic beauty. This study was carried out at The Chipopa, community of the department of Granada. The objective was analyzing the floristic composition, structures, floristic diversity and increment, of the secondary vegetation of the tropical dry forest. To obtain basic information on the arboreal vegetation that allows guaranteeing a management ecologically sustainable. There were two mensuration of the diameter of the arboreal species bigger than five centimeters in three permanent plots. The plots were of 0.25 hectare and were established during the period 2006 and 2009. A total of 43 species were identified represented in 26 botanical families, being the most representative Fabaceae, Euphorbeaceae, Hipocrataceae, Mimosaceae, Rubeaceae. The diversity of species is a little bigger in the 2009; confirming in this way that the forest follows a slow but sure process of enrichment floristic. The periodic increment annual average was of 0.58 cm year-1. As the time the forest reaches a structure with trees of all the sizes and a bigger composition of species. It is recommended to apply silvicultural treatments such as lianas liberation, thinning to improve increment of the species.
