Contribución al conocimiento de la vegetación de las sabanas de Casanare (Colombia)

We studied plant diversity in forest plots of bosques de galeria, bosques de vega, morichales, matas de monte, bancos de sabana, bajos de sabana y esteros, as well as ad libitum inventories . A total of 318 species and 80 genera of 206 families were found, being Poaceae the most diverse family with 29 species, followed by Euphorbiaceae with 17 species. The most diverse genera were Phyllantus and Panicum with seven species. The types of vegetation with the greatest diversity were bosques de galeria, bajos de sabana and morichales. The composition of families in forests is similar to that reported in other studies, but species composition is different suggesting local dominance due to spatial heterogeneity. With this study, there was an increase in the number of species recorded for the department of Casanare from 1479 to 1562.
