Abstract

In order to characterize the vegetation of the montane yunga forests in the south of the Río Abiseo National Park (La Sata sector), we installed 14 0.1 ha plots in four vegetation types: grassland, forests with trampled understory, forest on slope and remnant forest. The first three forests had a variable anthropogenic use before the establishment of the national park in 1983. We calculated Woody plant abundance basal área and the distribution of Woody plants by diameter and height classes, we also determined the importance value index for each species. We registered 96 especies (in 48 genera and 33 families) in the four vegetation types. The most species rich families were Asteraceae, Chloranthaceae, Cyatheaceae, Lauraceae, Melastomataceae Rubiaceae, Piperaceae and Rosaceae. The most abundant species were Weinmannia latifolia C. Presl, followed by Miconia aff. firma J. F. Macbr. and Myrsine coriacea (Sw.) R. Br. ex Roem. & Schult. The most species rich genera were Cyathea, Miconia, Persea, Axinaea, Solanum and Piper. The distribution by diameter classes showed reversed-J distribution for all forests studied, suggesting an adequate regeneration process. Ecologically important species included Escallonia myrtilloides, Weinmannia latifolia, Miconia cf. neriifolia, Miconia aff. jahnii, Myrsine coriacea and Gynoxis cf. congestiflora. Our results showed that the floristic patterns for the La Sata forests are similar in composition and structure to other forest present in this ecosystem in Peru. [ABSTRACT FROM AUTHOR]
