Estructura y diversidad vegetal del bosque protector Cashca Totoras en el sector Santiago, canton San Miguel, provincia Bolivar

Abstract

The present research: To determine the structure and vegetal diversity of the protective Forest Cashca Totoras in the sector Santiago Cantón San miguel Province of Bolivar; with the help of a GPS, field materials was carried outh the georeferencing of the Forest obtaining 6537 ha, for this work the stratified sampling desing was used, ten sampling units of 400 m2 were installed, where samples of the spices were taken arboreal species to later identifi them in the herbarium family, genus and species of most species are divide into 3 strata the variables taken in the unit of permanent sampling are: total height, the CAP ( circunference at chest height) and common name of the species in the sub UMP ( S UMP) were marked on tres with another paint color and measured on individuals with a DBH great 2.5 cm. And less than 7.5cm, we proceeded to take the total height, CAP and the common name of the species to calculate the values of IVI, IVF, diversity and floristic similarity, in addition we obtained the índices of Shannon and Simpson give as a resul species which predomínate in the forest are Weinmania sp, Oreopanax ecuadorensis, Polylepis sp since there i a greater predominance of these species within the Forest, significant differences were found between them. A total of 1615 individuals clasified in 44 species and 23 families the highest conservation, diversity and regenaration, are evidenced in the very humid montane forest. It is concluded that the most representative species were: Myrtus comunis., Weinmania sp., Clusia flaviflora., Ginoxys hally., Ficus sp., Cedrela montana., and Hedyosmun acabrum.
