| Abstract | The Cerrado region currently is subject to fast deforestation and to high rates of land use change. Increasing urbanization contributes to losses of the natural landscape, considerably reducing native vegetation and diversity, and thus impeding natural processes in remaining fragments. The objective of this study was to evaluate the effect of a planting of native species and of bird perching structures for the restoration of a perturbed area of Cerrado sensu stricto in the urban area of the Federal District, Brazil. The first chapter of this Master dissertation evaluates a planting of native species from Cerrado for the restoration of a 75 x 90 m (6,750m) perturbed area of the National Institute of Meteorology (INMET), originally covered by Cerrado sensu stricto, nowadays dominated by Brachiaria sp. Before the planting, the Brachiaria sp. was removed (native plants that had regenerated were maintained) to decrease the competition with juvenile plants, and the surface of the soil was raked to decreaseits compactation. The planting had been conducted in November 2004. Nineteen native species from Cerrado were chosen for the planting, nine species were from savanna (Astronium fraxinifolium, Bowdichia virgilioides, Caryocar brasiliense, Dipteryx alata, Eugenia dysenterica, Hancornia speciosa, Hymenaea stigonocarpa, Solanun lycocarpum, and Tabebuia caraiba) and ten from forest physionomies (Anadenanthera colubrina, Anadenanthera peregrina, Copaifera langsdorffii, Genipa americana, Hymenaea courbaril, Inga cylindrica, Myracrodruon urundeuva, Myroxylum peruiferum, Ormosia stipularis, and Tibouchina stenocarpa). A total of 886 juvenile plants (approximately 46 per species) were planted as young individuals (age varing between 5-10 months), except for those of S. lycocarpum which were planted from seeds. The distribution of individuals (sample units) was in hexagonic rings for 19 species, with distances of 3 by 3 m to adjacent plants. In each planting hole (0,3 m wide, 0,6 m deep), 0,1 kg of chalk, 1 kg manure and 0,15 kg of chemical fertilizer (4-14-8 NPK) were added prior to planting. At half of the individuals, all |
