Abstract

A rainforest chronicle: a 30-year record of change in structure and composition at El Verde, Puerto Rico.

Abstract

Stand parameters were recorded over 33 yr (1943-76) in a forest dominated by Dacryodes excelsa and Sloanea berteriana. In the early stand, secondary species were common and biomass and basal area accumulated rapidly. Many new species entered the stand and the number of stems increased. In the 1970s, biomass and b.a. accumulation had slowed down to approach a steady state, and fewer stems and species were recorded. It is suggested that the early measurements reflect rapid recovery following the last severe hurricane, which occurred in 1932.
