Caracterização do comprimento longitudinal das árvores do cerrado em Corrente - PI

Abstract

This study aimed to characterize the arboreal vegetation structure in two sample areas of the Cerrado biome located in the municipality of Corrente, southern Piauí, focusing on the identification of the predominant phytophysiognomy and the assessment of anthropogenic impacts. The transect walk method was used to analyze the longitudinal distribution of trees, including measurements of height and spacing between woody individuals with a diameter at breast height (DBH) greater than 5 cm. The results indicated that both areas fit the Dry Forest phytophysiognomy, a forest formation within the Cerrado biome, with a medium arboreal stratum, tree heights ranging from 15 to 23 meters, and canopy coverage exceeding 90%. Area 1 showed greater average spacing between individuals (6.04 m), while Area 2 exhibited higher density (4.10 m) and greater evidence of anthropogenic disturbances, such as trampling, solid waste, and trails. These findings highlight the importance of monitoring vegetation structure for conservation planning and sustainable management, especially in ecotonal and environmentally sensitive regions under increasing anthropic pressure
