Pollen influx data derived from a sediment core from a small crater lake were related to two population growth models. Doubling times for some tropical rainforest tree taxa, estimated from the models, are 63–165 years for angiosperms and 199–355 years for conifers. These values are generally higher than those for temperate forest trees in the Northern Hemisphere. The results show that fossil pollen data can provide useful information on tree population ecology in tropical areas.
