Abstract
TINOCO RODRIGUEZ, Fernando; BARRAGAN ROMERO, Jeimmy Bibiana and ESQUIVEL, Héctor Eduardo. Structure and Floristic Composition of two Premontane Forests Fragments in the Municipality of Villeta Cundinamarca. rev. cienc. [online]. 2014, vol.18, n.2, pp.39-50. ISSN 0121-1935.
We describe the floristic composition and structure of two premontane forest fragments at the city of Villeta in Cundinamarca, Colombia. All individuals with a diameter at breast height ≥ 10 centimeter were counted in a 0.1 ha plot of each forest. A total of 67 species in 45 botanical families were recorded; with Lauraceae, Melastomataceae, Moraceae, Myrtaceae y Euphorbiaceae being the most abundant and diverse. La Esmeralda fragment showed a large abundance, with 48 species and with Quercus humboldtii, Alfaroa colombiana, Guatteria lehmannii and Clethra fagifolia as the most abundant. At San Isidro fragment only 42 species were recorded and Clethra fagifolia, Hedyosmum bonplandianum and Meriania speciosa where the most abundant. Six of the most abundant families were registered in both places. The floristic diversity was similar in the two fragments (H 3,5 y 3,3), but the index of similarity was low, only 29,3% of the species were shared. The results showed that these forests have a low diversity, since we registered fewer number of species and individuals than has been reported in other premontane forests
