Abstract

Although the conservation of tropical biodiversity depends on protected areas, there is still a very large ‘gap’ of
knowledge on the flora of Brazilian reserves, especially in the Northeast region of Brazil. Field and herbarium surveys
of the phanerogamic flora of the Ubajara National Park, located on the Brazilian Northeast, were made and analyses on
phenology and dispersal syndromes were performed. 418 taxa (213 trees and shrubs, 100 terrestrial herbs, 68 climbing
plants, 33 sub-shrubs, two epiphytes, one hemiparasite and one aquatic herb) were recorded. The most representative
families were: Fabaceae, Malvaceae, Asteraceae, Rubiaceae and Euphorbiaceae. The annual flowering / fruiting peak
hypothesis was not fully confirmed, therefore, the forest may be an important food resource for the fauna all year long
(especially in the moister region). Zoochory was the predominant dispersal syndrome in the moister area, whereas,
autochory and anemochory together, predominated in the drier area.

Keywords: biodiversity, mountain forest, protected areas, evergreen forest, deciduous forest.
