In order to gain some knowledge on the processesthat maintain tree species diversity, we conducted an analysis of three different laurel-forest plots of the Anagamassif (Tenerife), varying in canopy composition but growing under similar environmental conditions. For eachplot we recorded basal area of the canopy trees (h > 1:30 m), the density of suckers and seedlings (h < 1:30 m), aswell as seed-bank composition. The plots have similar regeneration composition, which appears to be independentof differences in canopy composition. Laurus azorica is the most common seedling species, whereas Prunuslusitanica is the most abundant species among suckers and basal shoots. Neither Erica arborea nor Myrica faya,the two main canopy trees in one of the plots, were found in any of the stands as seedlings or suckers, despitetheir existence as viable seeds in the seed-bank. The regeneration composition and the canopy composition inone of the plots is remarkable different, revealing differents dynamics processes in the three plots. The resultssuggest the existence of three well-defined ecological groups: pioneer (regeneration primarily by seedlings), nonpioneer (regeneration by seedlings and suckers) and remnant species (regeneration primarily by suckers).Thesethree groups and the effect of small scale disturbances (natural and human-induced), could help to understand themaintenance of tree species richness.
