AB Managed laurel forests in the Canary Islands have undergone clear-cutting with rotation periods ofless than 30 y. Forest owners have recently requested a drastic reduction in the cutting interval. Theeffects of this new harvesting cycle on organisms like epiphytic bryophytes are not well known.This study investigates how time since last clear-cut, host species and characteristics of tree zonesinfluence the biomass, cover and richness of epiphyte bryophytes in managed laurel forests in LaPalma, Canary Islands. Four forest ages (8, 15, 25 and 60 y) and three host tree species (Erica arborea,Laurus novocanariensis and Myrica faya) were studied.Biomass, cover and richness of bryophytes increased through the chronosequence, both at the levelof each plot and overall for L. novocanariensis. Most of the biomass (53%) and richness (81%) wasconcentrated in one of the tree species (L. novocanariensis), in plots for which 60 y had elapsed sincethe last clear-cutting. Trunks supported greater bryophyte biomass and richness than canopies, evenin the oldest plots.Our results suggest that the current rotation periods used to manage laurel forests are insufficientlylong to allow for complete reestablishment of epiphytic bryophyte assemblages.
