This particular kind of swamp forest (yolillal) is composed of a nearly pure stand of Raphia taedigera, a palm species that grows in clumps. The leaves of yolillo grow to nearly 15 m in length and upon falling seem to eliminate the few other species of trees that might grow in water. One hundred clumps of the palm were marked and the numbers of live, dead, large, small, flowering, and fruiting stems were recorded. The presence of saplings of other tree species was also noted. The results suggest that the Raphia swamp forest is not an intermediate stage of succession but rather a climax community.
