ABSTRACT
A phytosociological study of 59 relevés was carried out at Laguna Quila, National Park Lagunas de Zempoala, México, using the Zürich-Montpellier approach. Eleven communities were identified and described. A distinction was made between a submerged and a helophytic hydroseral vegetation. A pronounced humidity gradient was identified in a north-south direction, and also a continuous desiccation was observed. A vegetation map scale 1:1900 is included. 21 families of vascular plants including 41 species and 33 genera have been identified. Families best represented include Cyperaceae with seven species and Ranunculaceae with four species. Phytogeographical analysis on the generic level revealed that the temperate component reached 65%, the cosmopolitan 30% and the tropical 5%. The species of Laguna Quila have a wide distribution in Mexican hydroseries and elsewhere in temperate America. Aquatic and semi-aquatic communities are vanishing rapidly in Mexico, and it is important to understand the dynamics for adequate management of this natural resource. In order to protect this lake it is recommended to control the water extraction of the laguna, to exclude cattle and other activities who can affect indirectly Laguna Quila.
