The objective of this study was to evaluate the annual variation in seed yield of crabwood, and discuss implications for multiple use management of the species. Data were collected in a forest area in the southern of Roraima State in a permanent plot of 9 ha (300 m x 300 m) with a natural population of crabwood. Seed production was monitored of 115 trees during four years. Seed yield varied among years. May to July was the period of bigger yield. Few trees (22.6%) concentrated the bigger part of seeds yield (80.7%) and the most productive trees had diameter at 1.30 m above ground level between 40 cm - 70 cm. Therefore we recommend 70 cm as minimum cutting diameter for wood exploitation. For sustainable crabwood seed management we recommend to restrict seed collection from the most productive trees and only during the period of maximum seed dispersal.Downloads
