OSPINA M, ROMÁN  and  PAZ C, JUAN PABLO. FLORISTIC CHARACTERISTICS OF A OAK FOREST (Quercus humboldtii) ON THE PLATEAU OF POPAYÁN (CAUCA). Rev.Bio.Agro [online]. 2012, vol.10, n.2, pp.243-248. ISSN 1692-3561.

To study the floristic characteristics of a oak forest (Quercus humboldtii) established a plot of 9600 m² divided into 24 subplots of 20x20 meters, where there was scientific name, diameter at breast height dbh, total height and branching height, light condition 10 cm in each > and quality for individuals with stem diameter at breast height subplot were enrolled 10x10 meter plots to record information about individuals with 1.5 meters in height and dbh > 10 cm and 5x5 plots to record established regeneration tree species < 0,40 meters, palms and large herbaceous. In 0.96 were reported a total of 51 species, grouped 44 genera and 33 botanical families for the three size categories, the most abundant and well distributed in the category > 0.4 m < 1.5 m in height, were Palicourea angustifolia and Quercus humboldtii, the species with heavier ecological an Importance Value Index IVI were Quercus humboldtii 153 and Clethra revoluta with 37, while all other species reported low levels of abundance, frequency and basal area. The average density of trees >10 cm in diameter at breast height was 455 ha^-1, representing a basal area of 15.8 m²ha^-1 indicating that it is a young forest.
