The regularization of rural properties in the molds of the New Forest Code depends on the silvicultural studyof the native species of the Brazilian biomes. The of this study was to evaluate the initial growth offive native tree species of the Atlantic Forest, with a view to their use in forest restoration projects. Thefollowing species were produced in the nursery, planted in the field, and evaluated for performance: Araucariaangustifolia, Mimosa scabrella, Trichilia claussenii, Schizolobium parahyba, and Cordia trichotoma. Thesespecies were distributed in two different areas, based on the randomized block experimental design. Inexperiment 1, the species A. angustifolia, M. scabrella, and C. trichotoma were distributed in three randomizedblocks, each composed of 11 plants of each species. In experiment 2, the species A. angustifolia, M. scabrella,T. claussenii, and S. parahyba were distributed in three randomized blocks, each one composed of five plantsof each species. In general, S. parahyba and M. scabrella showed faster development than the other speciesand, in this regard, are promising candidates for forest areas constitution or reconstitution in which there isinterest in obtaining economic returns in less time. Araucaria angustifolia and T. claussenii showed relativelylow development, whereas C. trichotoma showed intermediate development in relation to the other speciesstudied. Despite their differences in performance, all species proved to be suitable for use in reforestation,mainly in the region where the study was developed.
