Abstract

From the 1960s to 1980s, the cultivation of Pinus species was deployed to areas of Cerrado at the Ecological Station of Santa Bárbara (EEcSB), in the municipality of Santa Bárbara, in the state of São Paulo, Brazil. Given the negative impact of this cultivation on native species, the management plan of EEcSB (2011) predicted studies, such as those conducted by the team of Dr. Giselda Durigan, aimed to eliminate gradually exotic species for the regeneration of native vegetation. At EEcSB species are reoccupying areas where Pinus sp. has been removed. The knowledge of the morphological patterns of these species can be useful for managers to select species in restoration programs for these areas. In addition, if the species have the resprouting ability that is the main attribute related to regrowth, the impact caused by the long cultivation period of Pinus sp. on the underground bud bank is not known. Therefore, this project aims to: a) analyze the morphological and anatomical features that allow regeneration of some species in areas after the clear-cutting of Pinus sp. and subsequent burning of the remaining material; b) investigate the reserve and protective compounds in belowground systems of species surveyed in item a; c) compare the underground bud bank of areas that are still under the cultivation of Pinus sp. with areas of natural Cerrado.
