Exploitation of Hollow Trunks by Tropical Trees

Abstract
Observations were made on felled trees from an undisturbed lower montane rainforest in Jamaica. Hollow trunks are of significance to forestry and also to their possible ecological significance as mineral supplies. Hollow trunks found in Guarea swartzii, Drypetes alba and Pouteria multiflora are discussed. The "soil" in these trunks contained roots of the hollow tree as well as a variety of epiphytes and other species. It is not clear if the possible advantage to the hollow tree is outweighed by competition from other individuals. The pH of the material within the hollow trunk was very different from the soil substratum indicating possible differences in mineral availability.
