The basic stem density (included wood and bark) information taken from 125 species of trees of the Colombian tropical dry forest of the Caribbean coast was shown. The distribution of the species frequencies was adjusted to a normal distribution, with a 75% of the values of density between 0, 4 and 0, 8 g/cm3. The most frequent type, with 17, 6% of the species and 17, 7% of the trees’ total, was estimated between 0, 5 and 0, 6 g/cm3. The average (approximated standard variation: 0,597 ± 0,18) of the wood’s density belongs to the range reported previously for similar forests in the Neotropical region. Additionally, a great variation between species was spotted, according to other reports. This data represents, for the region, its first published information and can be reference for a wide number of studies focus on the structure and dynamic of the Caribbean forests.
