The floristic associations, the searching into the list of species at risk of the NOM-059-ECOL-2010 and analysis floristic similarity were done. The list includes 51 families, 121 genera and 183 species in three different vegetation types: tropical deciduous forest, thorn forest and gallery forest. The major families considering the number of species were Mimosaceae, Fabaceae, Burseraceae, Caesalpinaceae, Apocynaceae, Malpighia-ceae and Rubiaceae. The species number was largest in Bursera genus. The study denotes the presence of four species at risk in Cocula according to the NOM. Two are threatened and two endangered.
