Abstract In the present study we analyzed the structure and composition of a tropical dry forest fragment in the Natural Reserve Sanguare (San Onofre, Sucre, Colombia). We established the richness of plants and the structural parameters to measure the organization and dynamics of the forest. In each forest fragments we made a vegetation survey with RAP’s modified transect type method. We made taxonomic identification, species counts and structure measurements such as height and DBH, to establish the most important families, genera and species; the growth habits and vegetation profile. We found 658 individuals, grouped in 37 families, 81 genera and 82 species. The most important taxonomic in terms of richness were Malvaceae, Fabaceae, Caesalpinaceae, Mimosaceae, Rubiaceae and Moraceae; while as an abundant taxa Caesalpinaceae, Sapindaceae, Malvaceae, Bignoniaceae y Rubiaceae where important. The dominant habits of growth were trees and the palmetum had a high representation as an outlier to the dry forest. The greatest height of trees was 15 meters on average, which allows us to infer the forest is in an early succession.
