In the Western Ghats part of Uttara Kannada district in Karnataka, sixteen non-timber forest product species were monitored for yield and yield attributes during the years 1997, 1999 and 2000. Average fruit number per tree was computed and yearly variation in fruit number was compared. Correlation coefficients were computed for yield with its attributes such as girth, crown size and height. Further, the correlation coefficients among yield attributes were also computed.In most species, there was significant difference in fruit number between years, indicating that most tropical tree species exhibit supra-annual cycle of reproduction. An important observation made was that in most species, the yield between two consecutive years was significantly different. Correlations among various yield attributes indicated that though the coefficients among the yield attributes were consistent, correlation with yield was highly variable, indicating that annual variations may be because of the environmental attributes that influence yield. Therefore, the predictive ability of yield for fruits is difficult.
