A floristic characterization associated with the Dendrobatidae (Amphibia: Anura) habitat was carried out in the Piangüita community (3°48'30"N, 77°11'32"W), northwest of Buenaventura on the Colombian Pacific coast. For this purpose, Gentry belt transects were used to make a census, in a 0.1 ha area in which all individual plants had a dbh of≥1 cm (measured at 1.3 m above the ground). In this, from very humind to pluvial tropical forest,, 855 individuals, distributed in 110 families, 308 genera, and 407 species were found in 10 transects (0.1 ha).. With the data obtained and organized, different structural parameters were calculated. The families with the highest Importance Value Index (IVI) were Arecaceae (1.91), Rapateaceae (0.34), Moraceae (0.12), Melastomataceae (0.11), Rubiaceae (0.095), Euphorbiaceae (0.073), Fabaceae (0.066), Marantaceae (0.038), and Myristicaceae (0.025). The distribution curve of the individuals is in the form of an inverted "J". The Shannon-Wiener diversity index is 3.08; the species accumulation curve was not asymptotic. Dendrobatidae frogs were found in five out of the 10 transects made.
