A comparative study of floristic composition, structure and pole diversity in two ecosystems at the 50k CPO-09 oil field in the Orinoco region of Colombia

A structure and composition study of poles in two wooded areas of Colombian Orinoquia totalling 10 465 hectares is presented. A 1: 10 000 scale map was made for mapping gallery forest and high dense forest from tierra firma, in order to implement a field stratified sampling, in which each sample uni...

Description
Summary:A structure and composition study of poles in two wooded areas of Colombian Orinoquia totalling 10 465 hectares is presented. A 1: 10 000 scale map was made for mapping gallery forest and high dense forest from tierra firma, in order to implement a field stratified sampling, in which each sample unit is selected randomly. Data from 16 sampling units of 0.1 ha each from both ecosystems (for each of them) were collected, and included information about individuals with diameter at breast height(DBH) more than 10 cm and taking data of species, circumference at breast height (CBH), total height and height to crown base . Higher species richness was found in gallery forest with 81 species whereas tierra firma had 76. The latter however, had greater heterogeneity and a better vertical structure. Both ecosystems included the presence of 12 endangered species in different categories according to the Colombia red data book, Resolution 0192 of 2014 of Colombia, IUCN and CITES.
