Background:Forestry management modifies the diversity,structure,and functioning of intervened *** extraction reduces tree density and basal area,leading to changes in the communities of vascular *** objective of this study was to evaluate the diversity and biomass of vascular epiphytes in Quercus trees remaining in two pine-oak forest stands that have been subjected to two stages of the Silvicultural Development Method(release cutting,and thinning)in comparison with an unharvested old-secondary forest in southern *** each treatment,richness of epiphytes present on 60 oak trees was recorded and their dry biomass *** calculated the true diversity(Hill numbers)and beta diversity using the Jaccard coefficient of similarity,and generated rank abundance curves per taxonomic epiphyte group(bromeliads,orchids,ferns and others).For each treatment,the relationships between overall diversity and epiphyte biomass to the host trees basal area were analyzed using log linear ***:We recorded a total of 67 species of epiphytes species belonging to 10 families hosted by five species of *** greatest species richness(^(0)D)was recorded in the old-secondary *** common(^(1)D)and dominant(^(2)D)species were recorded in the release cutting than in the other *** diversity and biomass were both slightly related to host tree basal *** of epiphytes was similar(60%)among treatments,although orchids,bromeliads,and other families were more diverse in the old-secondary *** bromeliad species were shared across all treatments,although orchids presented the most exclusive species in the unharvested *** bromeliad Tillandsia seleriana provided the greatest contribution to biomass in all treatments,followed by the orchid Camaridium *** linear models indicated that epiphyte diversity was significantly related to treatment,and epiphyte biomass to basal area of host ***:Alt
