The velvet tamarind (Dialium guineense Willd) is one of the key species for domestication in Sub-Saharan Africa. In order to help the sustainable  management and conservation of this species, its structural characteristics and ethnobotanical traits were studied in the 4 vegetation types (typical  dense forest, degraded dense forest, young fallow and old fallow) of the  Lama forest reserve. A forest inventory was carried out in 100 randomly  selected squared plots of one ha each in the 4 vegetation types. One  rectangular plot of 0.15 ha was set up within each 1 ha plot for their   structural descri ption. Moreover, 10 squared plots of 10 m side were  established on one of the diagonal in each one ha plot in order to estimate regeneration density. An ethnobotanical survey was also carried out among 100 randomly selected people of the Holli, Fon and Adja sociocultural  groups living adjacent to the forest. Results showed that there were   significant differences between the 4 vegetation types according   dendrometric parameters. Stem diameter structure showed a nonnormal
shape. Ethnobotanical survey revealed that D. guineense is an agroforestry species and most of ethnobotanical knowledge is held by men of Holli sociocultural group.
