Habitat comments: "hot, rainy and humid, without dry season... The low-impact standard operation is based on an inventory that selects trees with more than 50 cm DBH (Diameter at Breast Height)... Around 15–20 m3 of roundwood were extracted per hectare (with a maximum of six trees extracted per hectare) during the first rotation cycle, which lasted 30 years"
