FLORISTIC AND PHYTOSSOCIOLOGICAL STUDY OF GALLERY FOREST IN CERRADO

Abstract

It was performed the phytosociological study of gallery forest to known the composition and structure of this vegetation. The study area located in Lava Pes stream at the experimental farm of State University of Goias, Câmpus Ipameri. The point quadrant method was used with 10m between points and 20m between transects. Were sampled 412 individuals with DBH > or = 5 cm, at 103 points, totaling 1030 linear meters and 2.6ha. Was identified 78 species, 62 genera and 37 families. The Shannon diversity index H' was 3.58, considered high for the Cerrado. The most representative families in number of species: Fabaceae (15), Vochysiaceae (8), followed by Annonaceae, Sapindaceae, Anacardiaceae, Melastomataceae and Malvaceae (3). Chrysobalanaceae, Myrtaceae, Malpighiaceae, Sapotaceae, Callophyllaceae, Polygonaceae and Rutaceae were represented by two (2) species each and the rest by only a single species. Qualea grandiflora Mart. was the most abundant species, with 65 individuals, and showed the highest frequency, density, importance value and index cover. The total basal area was 12.82m² / ha, equivalent to other studies in similar vegetations. The species with the highest basal area were Cariniana rubra Gardner ex Miers (2.67m²/ha), followed by Qualea grandiflora (1.48m²/ha) and Qualea parviflora Mart. (1.22m²/ha). Due to high biodiversity, the conservation status, and presence of endangered species ( Dicksonia sellowiana Hook. and Euterpe edulis Mart.), this forest is important for the recovery of degraded areas and for biodiversity conservation.
