Abstract

Regeneration patterns of Abies faxoniana, Betula utilis and B. albosinensis in central Sichuan, China were interpreted by stand structural analysis (age, size, horizontal patterning) of tree populations in old-growth (>250 yr) stands. Seedlings, saplings and young trees were scarce in stands where bamboo Sinarundinaria fangiana impeded tree regeneration. Shrub density and woody plant species richness were lower in stands with high bamboo cover. A. faxoniana and B. utilis relative densities were similar where bamboo was dense, A. faxoniana was more than twice as abundant as B. utilis where bamboo cover was low or absent. Both species regenerated in canopy gaps, but A. faxoniana less so than B. utilis where bamboos were dense. This produces higher Betula density in bamboo stands. Partitioning of gaps by size may contribute to coexistence of A. faxoniana and B. utilis. -from Authors
