Аннотация: One of the most popular approaches in functional plant ecology is the study of CSR strategies based on Grime’s theory. However, this approach to the study of epiphytes has not been used yet. We assumed that the response of epiphytes to disturbances would be different than that of terrestrial plants. Namely, this would lead to a decrease in epiphytes with the competitive (C) strategy and an increase in the number of stress-tolerants (S) in disturbed forests. We found that in primary forests, representatives of the Orchidaceae family dominate in terms of speciesnumber, while in disturbed forests, Orchidaceae and Polypodiaceae dominate.Epiphytes demonstrate a tendency to a more pronounced C- strategy than tropical forest trees and to a more R- strategy than terrestrial herbs. At the same time, most epiphytes gravitate toward the radical S- strategy. In the primary forest, epiphytes adhering to competitive, ruderal, and mixed strategies are widelyrepresented. Representatives of these strategies disappear in secondary forests sothat predominantly (S) stress-tolerant and one (C) competitive species remain. Inthe studied secondary formations of tropical forest, the lower forest layer isoccupied by succulent orchids and ferns. Undisturbed tropical forest ischaracterized by the presence of sciophytic and mid-stem epiphytes.Disturbance of the tropical forest structure leads to the loss of epiphyticspecies of the lower synusiae, while the advantage passes to stress-tolerantsucculents. Thus, the change in the functional diversity of epiphytes is directlyrelated to the change in the structure and layering of the forest canopy
