Topoclimatic Zoning of Three Native Amazonian Forest Species: Approach to Sustainable Silviculture

Abstract

Anthropized areas in the Brazilian Amazon require detailed mapping to identify zones for sustainable use. This study developed a topoclimatic zoning framework to evaluate the conservation and agroforestry potential of three native species: Carapa guianensis (Andiroba), Dipteryx odorata (Cumaru), and Bertholletia excelsa (Amazon Nut). The hypothesis was that integrating topographic and climatic data can effectively identify high-potential areas for these species to support forest restoration and sustainable management. This study applied ecological modeling and Geographic Information System (GIS) tools to classify zones into high, medium, and low potential for each species. Results showed Carapa guianensis has high potential in 64% of anthropized areas, Dipteryx odorata in 72% of the Legal Amazon, and Bertholletia excelsa in 58%, highlighting their adaptability and strategic value for restoration efforts. The findings emphasize the importance of topoclimatic zoning as a tool for conservation and sustainable use strategies. By aligning with Brazil’s Payment for Environmental Services (PES) Law, this approach can foster agroforestry practices, enhance biodiversity conservation, and strengthen the Amazon bioeconomy, ensuring ecological resilience and sustainable development.
