Abstract A sustainable yield management system is proposed for Euterpe edulis (‘Palmiteiro’) based on field studies. Since this Brazilian palm integrates the forest in the intermediate succession stages and grows naturally in shaded areas, its exploitation requires neither forest destruction nor forest gaps. This system, based on the cyclic exploitation and on equating species exploitation, was accomplished by defining three basic parameters: (i) the number of seed producing trees per area and their maintenance to ensure natural regeneration and the maintenance of population genetic structure and diversity levels, (ii) the available stock, used to determine the degree of exploitation, and (iii) the species increment rates in order to define the cutting cycle length. These parameters were estimated from permanent plot inventories. In São Pedro de Alcântara (SC), the exploitation of ‘palmiteiro’ trees with diameter at breast height above 8.5 cm, leaving 50 seed producing trees, yields 51.2 kg/ha of heart-of-palm (‘palmito’) in the first cycle. The sustainable yield management of this palm tree is (i) important to conservation because it allows the demographic and genetic structure maintenance, and (ii) economically viable because its edible product, the heart-of-palm, which has high economic value, can provide subsistence to several traditional communities.
