Floristic composition and vegetation structure were studied in 13 pastures located at Los Tuxtlas Range, in Veracruz. The studied sites were originally covered by tropical rain forest. Today's currently used pastures are dotted with rain forest remnant trees, spared during forest-cutting. These large isolated trees are primarily used as a source of shade, food (fruits), firewood or lumber. Results indicate that pastures are highly heterogeneous in species composition as well as in vegetation structure. This heterogeneity is related to the presence of isolated trees in the pastures. Isolated remnant trees function as nursery plants for native woody species by facilitating the establishment of zoochoroius species, deposited under their canopies by fruigivorous vertebrates (mainly birds or bats).
