from Part VII - Cloud forest conservation, restoration, and management issues
Published online by Cambridge University Press: 03 May 2011
ABSTRACT
Vascular epiphyte biomass and species richness were investigated in 16 anthropogenically disturbed pine–oak forests within an area of ~400 km2 in the Highlands of Chiapas, southern Mexico. Epiphyte biomass on 35 host oak trees in six diameter classes varied from 0.8 to 243 kg dry-weight and comprised 13–34 species. The observed variation in epiphytes could be attributed to type and intensity of past forest disturbance as it affects present-day stand structure, as well as to site position within the landscape. To help preserve the diverse regional epiphyte vegetation it is recommended to abstain from cyclic clear-cutting, to spare a sufficient number of large “rescue” trees, and to consider epiphyte conservation at a large spatial scale. As an alternative to logging, various prerequisites are proposed for the sustainable harvesting of bromeliads from natural populations.
INTRODUCTION
In the footsteps of early explorers, successive epiphyte researchers have concentrated primarily on old-growth forests. From these studies it is evident that in pristine wet mountain forests epiphytes may contribute up to more than half of the vascular plant diversity and green biomass in the forest (Hofstede et al., 1993; Wolf and Flamenco-Sandoval, 2003; cf. Köhler et al., 2007; Gradstein 2008). Thus, epiphytes are possibly key to high-mountain forest ecosystem functioning.
