Abstract

Using mountaineering techniques, we studied the distribution and ecology of vascular (hemi)epiphytes on standing canopy trees in three lowland rain forest types of Guyana, South America: walaba forest, greenheart forest, and mixed forest. The differences in epiphytic vegetation of the three forest types appeared to be correlated with humidity conditions as determined by the soil, and with the tree species (host preference). The crowns are much richer than the trunks in epiphytic species and individuals. The bryophyte mats and accumulated debris in the lower canopy support a different vascular epiphytic vegetation than the middle and upper canopy branches, where the predominant epiphytes are adapted to drought and for growing on twigs.
