Efficiency of forest species for multiple use in Amazonia.
The growing of native and exotic forest tree species to recover disturbed areas of the Amazon region, besides reducing the deforestation pressure on the natural forest and providing profits to the rural producers, was evaluated in Manaus, State of Amazonas, Brazil. The forest tree species Acacia mangium, Bertholletia excelsa, Carapa guianensis, Cedrela odorata, Copaifera multijuga, Dipteryx odorata, Hymenaea courbaril, Sclerolobium paniculatum, Swietenia macrophylla and Trattinnickia burseraefolia were selected based on the growth rate, adjustment to full sunlight condition and potential for energy production and use in the sawmills. The 11-year-old trees were analysed for diameter at breast height, volume per hectare and survival. S. paniculatum showed the best performance in terms of DBH (mean DBH of 22.4 cm, 16.5 m high, volume of 475.6 m3/ha). B. excelsa, C. guianensis, C. odorata, C. multijuga, H. courbaril, and S. macrophylla presented moderate growth and showed low survival due to the attack of the shoot borer Hypsipyla grandella (Lepidoptera, Pyralidae). A. mangium trees were not evaluated due to the high mortality observed after 5 years old.
