The population density of copaiba trees in an area is usually very low. It is possible to find only one tree every 5 ha, but they may occur in densities of one to two trees per hectare. The production of oleoresin by species is fairly variable and can be influenced by genetic differences among species, habitat, soil, and intensity of exploitation . The production of oleoresin per tree ranges from 100 mL to 60 L per year. In addition, not all trees produce oil . Therefore, detailed investigations regarding extraction methods and equipment that do not harm the plant, correlation of genetic data to botanical identification of species, floristic inventory of copaiba populations, and ecological studies on its ecosystems are indispensable for the sustainable and rational use of this resource .
