Abstract

The plant associations of the phytogeographic province of Tehuacán-Cuicatlán Valley are described and classified according to the species dominance and physiognomy based on field samplings of 500 m2. The altitudinal distribution of the associations was determined conducting 250 m2 samplings located every 100 m altitude in throughout five environmental gradients. A total of 29 plant associations were recognized including nine associations dominated by columnar cacti, four types of deciduous forests, three types of Izotal, and six type of shrublands. Mountainous arboreal vegetation includes five types of forests, as well as a Mountainous lzotal. The vegetation  associated to aquatic environments along rivers and springs include Galery forests and "Tulares". The pronounced heterogeneity of Tehuacan-Cuicatlán Valley determines the diversity and the distribution of the vegetation associations.
