Abstract
The understanding of silviculture of native species in a determined region is fundamental for the selection of more appropriate species for using in ecological restoration. Trema micrantha (Cannabaceae), a pioneer species which is widely distributed, shading and attractive to birds, is intensively planted in restoration projects of the southeastern Brazilian Atlantic Forest. In order to get information regarding to the performance of this species in subtropical forests (subject to the yearly frosts), we analyzed its early growth in a planting carried out with 70 native tree species in 3 x 2 m spacing in four plots of 40 x 54 m. Semianually, we collected data of 72 individuals of Trema micrantha. These data were statistically analyzed using the Statistical Software Assistat-beta submitted to Tukey test (p<0.05) and graphically described by R. Trema micrantha showed excellent performance at 3.5 years of age in root collar diameter (12.01 ± 5.24 cm), total height (5.95 ± 1.44 m), crown projection area (22.56 ± 11.26 m²) and crown volume (61.34 ± 37.46 m³), enduring severe frosts with a yearly survival rate of 78%. Based on the results obtained, and considering that this species has broad natural distribution, we recommend its extensive use also in forestry restoration projects in the subtropical regions of Brazil.
