The density of epiphytes was almost three times higher on Plot 2 (11460 individuals ha-1) than on Plot 1 (4130 ha-1). Absolute densities and relative frequencies of all orchids and of Catopsis sessiliflora and T. deppeana was higher on Plot 1, and much higher on Plot 2 for the other three Tillandsia species (Table2). Lycaste did not occur at all on Plot 2 and T. deppeana only with three individuals. Reproductive individuals comprised between 1.4% (monocarpic T. deppeana) and 36.4% (L. aromatica) of the populations.
