Evaluación del estado de conservación y caracterización del estado poblacional de dos especies forestales priorizadas participativamente en la microcuenca del Río Chimborazo

Abstract

The demografic status of two forest species (Polylepis sp and Bubbleja incana) chosen in a participate way from the micro watershed on Chimborazo river; the desing used was 50x5m rectangular transects for the remnant wild forest area and sweep sampling for integrated systems área. For he current research some categories defined by IUCN (2001, 3.2 version) were used, the results werw that Polylepis incana and Polylepis racemosa Kunt for integred sistems can be considered as Vulnerable (Vu). The qualification obtained for these species in their phenotypic characteristics is 15 considered regular according to Heredia and Hofstede scale for Vulnerable (Vu) integred systems, their observable characteristics were 18 beloging to class 3 and considered reguLar according to Buddleja incana Ruiz & Pav evaluation criteria the (Quishuar – Remnant) wild forest was considerated regular and belongs to class 3. . For the mensuration variables, a correlation analysis between phenotype and mensuration variables as well as the sweep sampling and Quishuar transects sampling was carried out. The results were: 6,4cm DBH(diametre) in integreted systems, 10,08cm for remnant and an average height of 21,21 for integrated systems and 35,48 for remnant; it is recimmended to carry on with the reasearch yo the important in preservation of forest wild species in thr wáter shed of Chimborazo river. Key words: Forest evaluation, forest species, wild forest, forest systems.
