Abstract

The vegetation of a tropical cloud forest in northern Mexico was analyzed by the point- quarter and line intercept methods to determine the relative density, relative dominance, relative frequency and importance values of the woody and herbaceous species. The flora of the study site, near Gomez Farias, Tamaulipas, Mexico, represents a unique mixture of temperate and tropical taxa. Based on importance values, the upper woody stratum was dominated by oak (Quercus sartorii Liebm.), sweet gum (Liquidambar styraciflua L.), Turpinia occidentalis (Swartz) Don and Clethra macrophylla Mart, and Gal. The lower woody stratum consisted largely of Solarium nudum H.B.K. and Ampelopsis mexicana Rose. A total of 27 herbaceous species were encountered. Dominant syQCiQS included Aneilemageniculata (Jacq.) Woods and Ichnanthus nemorosus (Sw.) Doll. The results of this study indicate a vegetation dominated by temperate taxa with a significant representation of species with tropical affinities.
