Avaliação de métodos de restauração florestal de mata de tabuleiros-ES

Abstract

The aim of this study was to evaluate the growth of native forest species using different forest restoration methods and under different maintenance techniques, in a Tableland Forest. The experiment was installed in August 2007 in ‘Reserva Natural Vale (RNV), Linhares, ES, in a randomized blocks that consisted of 4 treatments and 3 replications: T1 (control) ants control; T2 selective chemical weeding, ants control and control of herbicide tolerant species; T3 same as T2 + planting of 14 pioneer species of the Atlantic Rainforest (spacing: 5 x 5 m) and intercalated seeding of Sesbania grandiflora in pits; and T4 same as T2 + planting of 54 species of the Atlantic Rainforest (3 x 3 m). Plants with DBH ≥ 5 cm were measured and identified at the time of the installation of the experiment and the three subsequent years. In the third year the IAF was also collected. The richest families in species in the third year of study were Fabaceae, Anacardiaceae and Lecythidaceae, and only in T4 species were observed in the four ecological groups. The higher leaf area index was observed in T3, indicating greater shading area.The ingrowth of plants and basal area was higher in T3 and T4, suggesting greater vegetation growth, where seedlings were planted. In general, the elimination of weed competition worked positively in the tree growth.
