Ecología de los robledales de altura (bosque de Quercus) maduros y en recuperación en la Cordillera de Talamanca, Costa Rica
Changes in structure of a Costa Rican upper montane Quercus forest were studied in 0.1 ha plots along a chronosequence including 8-20 yr old Early Secondary Forest (ESF), 25-32 yr old Late Secondary Forest (LSF) and mature Primary Forest (PF). In 1.2 ha 2854 stems > = 3.0 cm DBH belonging to 42 tree species were recorded. Tree species richness per 0.1 ha ranged from 15-30. Diversity indices did not change significantly during succession. Stem density was significantly higher in LSF than in PF, while basal area was significantly higher in PF than in ESF and LSF. Maximum canopy height and basal area increased lineraly during the first three decades of recovery. Height and DBH showed a significant, logarithmic regression for all forest phases. Highest Family Importance Values were found for Asteraceae in ESF and Fagaceae in LSF and PF. Density of seedlings/saplings < 3.0 cm DBH was highest in ESF. A period of 84.3 yr was estimated as the theoretically minimum time needed for structural recovery. The maximum canopy height and basal area recover 2-5 times slower in upper montane than in lower montane or lowland neotropical forests.
