COMPETIÇÃO <i>VERSUS</i> CRESCIMENTO DE ÁRVORES EM FLORESTA OMBRÓFILA DENSA NO ESTADO DO AMAPÁ - BRASIL

Abstract: O objetivo deste trabalho é o de avaliar, comparativamente, diferentes índices de competição independentes da distância (IID) em três dimensões de parcelas, e identificar aqueles que mais se correlacionam com o incremento diamétrico (IPA DAP), indicando o que melhor explica a competição entre as árvores do estrato arbóreo em uma Floresta Ombrófila Densa. Este estudo foi conduzido com dados do Projeto Bom Manejo (Embrapa/CIFOR/ITTO) – Manejo sustentável de florestas de produção em escala comercial na Amazônia b… Show more

“…The BAL index, for example, increases as the number of trees with larger individual basal area than the subject tree increases (Martins et al, 2011), i.e., larger values of the index correspond to smaller trees, which results in a negative correlation. On the other hand, the Glover & Hool index (GH) has a positive correlation with diameter growth, since larger trees will result in a larger value for this index (Vatraz et al, 2018). Most distance-dependent competition indices have a negative relationship with growth, as they usually are a sum of the interference of local neighbors (Tomé and Burkhart, 1989).…”

“…The BAL index increased its correlation with diameter growth as plot size increased and stabilized with a 2500 m2 square plot. The same plot size was considered optimal by Vatraz et al (2018) in the Amazon forest. However, this plot size may not be ideal in some cases, and literature also reports different plot sizes that maximizes the performance of the BAL index (Burton, 1993).…”
