FERNANDEZ MENDEZ, Fernando; CAMARGO MARTINEZ, Yeimy Katherine  and  SARMIENTO, Mónica Bibiana. PLANT BIODIVERSITY ASSOCIATED TO FOREST PLANTATIONS WITH Pinus caribaea MORELET AND Eucalyptus pellita F. MUELL. ESTABLISHED IN VILLANUEVA, CASANARE, COLOMBIA. Rev. Fac. Nac. Agron. Medellín [online]. 2012, vol.65, n.2, pp.6749-6764. ISSN 0304-2847.

Abstract. It was analized in a plantation located in the tropical rainforest, the possibility that native species forming an understory in Pinus caribaea and Eucalyptus pellita plantations. Were established permanent plots, within plantations by species, age and silvicultural treatment, also in the natural forest and savannah. Individuals were classified by size and habit. 49 families and 102 botanical species were identified. The highest and lowest diversity occurred in the natural forest and savannah with 53 and 18 species, respectively between plantations, there was greater diversity with P. caribaea with 46 species that in E. pellita with 38 species. The mixing ratio shows a heterogeneous vegetation in all uses. The richness indices of Margalef and Menhinick, show more species diversity in forest, plantations followed older and finally the savannah. Shannon and Simpson indices show all sites with heterogeneous vegetation. The treatments had statistically significant differences in number of individuals, species and size classes except forbs. Regarding abundance were three major groups: mature forest plantations, intermediate plantations, and young plantations with savannah. High diversity was observed between the threatments that shared less than 50% of species and abundances, according to indixes of Jaccard and Sorensen. Among plantations had the highert number of shared species.Concludes that in plantation grows understory plant biodiversity and don't prevent the establishment of native species.

Keywords : Commercial forest plantations; understory; plant succession; native species.
