AbstractAlthough the high diversity of plant species in the rupestrian fields has been primarily attributed to the existence of a set of distinct habitats; few studies support this assertion. The present study aimed to further investigate the relationship between physical and chemical attributes of soils with the diversity of plant species in this unique ecosystem. The rupestrian field is a unique vegetation formation that covers some of the southeastern Brazilian mountains in the transition of the Atlantic rain forest and the Cerrado (savanna). Different habitats occur according to soil characteristics (e.g.; presence of rocks; sand; fertility; hydrology; etc.). These attributes ultimately influence the vegetation that is highly adapted to the harsh edaphic and climatic mountain conditions. Five distinct habitats were studied by us: rocky outcrops; peat bogs; sandy bogs; quartz gravel fields; and “cerrado” (savanna). A floristic survey indicated that four families are found at greater frequency: Poaceae; Asteraceae; Cyperaceae; and Leguminosae. The greatest diversity of plant species was found in the rocky outcrops habitat; followed by cerrado; peat bog; quartz gravel grassland; and sandy bogs; respectively. The main difference in the floristic composition among these habitats was related to the dominant species. Trachypogon spicatus (Poaceae) was the most dominant species in the rocky outcrops; Axonopus siccus (Poaceae) in the peat bogs; Lagenocarpus rigidus (Cyperaceae) in the sandy bogs; Schizachyrium tenerum (Poaceae) in the cerrado; while Vellozia sp. 8 (Velloziaceae) dominated the vegetation in the quartz gravel grassland. This study demonstrated that physical and chemical soil properties strongly related the diversity of plant species occurring in the different habitats of rupestrian fields.
