Resumo
This work aimed to study the floristic composition and phytosociology of an area of cerrado
sensu stricto located on rocky outcrops in Parque Estadual dos Pireneus, municipality of Pirenópolis,
Goiás. The studied area is located between 15º47’71’’S - 15o47’77’’S and 48º49º’96’’W - 48o50’15’’W, at
the altitude of 1.355 m. Ten 20 m x 50 m plots were randomly sampled to include all woody individuals
with BD(30cm) ! 5 cm. We registered 30 botanical families encompassing 45 genera and 56 species. Myrtaceae
family showed the highest number of species (8), followed by Fabaceae and Melastomataceae
(6 each), Malpighiaceae (4) and Clusiaceae (3). There were 507 individuals/ha, the basal area was 3.91
m2/ha , and the standing dead trees represented 9.07% of the total number of individuals. Shannon’s
(H’) index was 3.33 nats/ind. Czekanowski similarity indices suggest that the beta diversity was high,
mostly due to variation in species density between plots. The area has a characteristic flora of this region
and species composition restricted to rocky outcrops adapted to shallow soils near the rocky substrate
as well as generalist species of Cerrado physiognomies.
