WOODY FLORA OF THE MUNICIPALITY OF COCULA, GUERRERO, MEXICO.

Abstract

A woody floristic study of the Cocula municipality, in the State of Guerrero, Mexico,
is presented. Botanical list of woody flora
made over a period of a year. 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, Malpighiaceae 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. Results
suggest biological heterogeneity of the
sampling sites. Afloristic similarity analysis
showed that the Machito de las Flores site
had more species diversity than other sites,
probably due to differences in physical and
ecological processes.
