Little knowledge on initial behavior of native tree species in recovering landscapes in the Amazon is a current concern for expanding reforestation in the region. Thus, the aim of this study was to evaluate the establishment of native tree species that could be used for reforestation in area previously covered by a pasture of brachiaria grass (Brachiaria brizantha) destined for intensive cattle rasing in the State of Rondônia. For this, there were performed previous diagnostic of landscape changes and the election of tree species based on the ecological group information. Some of the critical macronutrients for plant growth were supplied in the holes to alleviate nutrient deficiencies. In addition, growth and survival parameters were taken to evaluate the initial behavior of species. Six native tree species planted with different combinations (10mx10m, 5mx5m and 3mx3m) had survival rate and growth (total height, girth stem and crown projection area) measured in different intervals: 6-month, 12-month and 24-month after planting. All the species presented survival rate over 90% at 24 months and comparable growth indices to other native species under similar situation and in the region. Overall, Schizolobium amazonicum (bandarra), the non-identified legume tree 1 (acácia grande) and Colubrina glandulosa (sóbrasil) averaged over 90% the highest girth stem growth all over the area. S. amazonicum and the non-identified legume tree 1 (acácia grande) presented the best results for height and canopy area growth parameters, respectively. The combination among native tree species from initial successional ecological groups and fertilizer was favorable to promote reforestation in the conditions of the study area in Rondônia.

“…A madeira é leve, fácil de trabalhar, empregada na fabricação de brinquedos, marcenaria, papel, balsas e trabalhos de interior (Loureiro et al, 1979). Para Sampaio et al (1989), pelo rápido crescimento e boa forma do fuste, a espécie tem um bom potencial para programas de reflorestamento na região amazônica.…”

. RESUMO -O objetivo deste trabalho foi estudar o crescimento das espécies florestais pioneiras pau-de-balsa (Ochroma lagopus Sw.) e caroba (Jacaranda copaia D. Don) para a recuperação de áreas degradadas pela agricultura. Na área, situada no km 120 da BR-174, tinha sido plantado mandioca e banana e abandonada há 8 anos, formando uma capoeira de porte baixo e rala. O experimento foi instalado em maio/98, com e sem gradagem da área. O espaçamento foi de 3x3m, em covas de 20 cm (diâmetro) x 30 cm (profundidade), com adubação de 150g/cova de NPK (4-16-8) e calcário dolomítico na proporção de 3:1. Para a avaliação do crescimento, foram medidas a altura e o diâmetro das plantas aos 2 meses (julho/98) e a cada ano aproximadamente (junho/99, setembro/00 e maio/01). Os dados foram analisados através do delineamento inteiramente casualisado. A sobrevivência do pau-de-balsa foi maior em área gradeada (97,1%) do que em area não gradeada (92,5%), após o primeiro ano do plantio; da caroba, foi cerca de 90% e sem diferenças entre as areas. A altura e diâmetro do pau-de-balsa, foram maiores em área gradeada, a partir do primeiro ano, chegando no terceiro ano a 11,85 m de altura e 11,42 cm de diâmetro. Na caroba, a diferença ocorreu a partir do segundo ano e no terceiro chegou a 8,37 m de altura e 11,18 cm de diâmetro. Além de outros fatores inerentes às espécies, o solo mais friável das áreas gradeadas, possibilitou um maior crescimento em altura e diâmetro das duas espécies estudadas.

The experiment carried out at Br-174, km 120. After the use for cassava and banana plantations the area was abandoned for 8 years. The secondary forest that took place was of low height and sparse trees. The experiment was installed at may/98 and composed by harrowed and no harrowed areas. The seedlings were planted in 3 x 3 m spacing, in 20 cm diameter by 30 cm deep holes, with 150g of fertilizer NPK (4-16-8) and dolomite limestone in the proportion 3:1.To evaluation the growth were measured the height and diameter in july/98 and each year, approximately (June/99, September/00 and May/01). The data were obtained from planted species comparing harrowed and no harrowed areas in a full random design. The survival of pau-debalsa, was greater in harrowed area (97,1%) in relation to no harrowed area (92,5%) after one year of planting; and the survival of caroba, was 90% after one year of planting and showed no

Planting of forest species of timber interest helps to reduce the deforestation pressure on the Amazon forest, promotes sustainable development of the producing region and generates ecological benefits. The objective of this work was to evaluate the survival rate and growth of four native (Swietenia macrophylla, Parkia decussata, Dipteryx odorata and Jacaranda copaia) and one exotic (Acacia mangium) species in monospecific plantations (spacing of 2 x 2 m) established on areas previously used for grazing, in Itacoatiara, State of Amazonas, Brazil. When the trees were four years old, we collected biometric data )], e dados qualitativos obtidos por diagnose visual [taxa de sobrevivência (S; %), estado nutricional (NS, G: bom; D: deficiente; %) e estado fitossanitário (PS, S: satisfatório; NS: não-satisfatório; %). Para cada espécie considerouse três parcelas de 128 m 2 , cada uma com 32 plantas. Jacaranda copaia, seguida de Dipteryx odorata e Parkia decussata, foram as espécies mais recomendadas para o plantio em áreas com condições edafoclimáticas semelhantes às do presente trabalho, devido ao seu melhor desempenho para a maioria das variáveis.
