Resumo: | Mixed plantations of indigenous tree species have been widely used in the restoration of degraded Atlantic forests which had been converted to pastures. This study used ecological indicators to evaluate the status of restoration in mixed plantations at the Po?o das Antas Biological Reserve, Southeastern Brazil. Study sites involved mature forests (F), 8-year-old mixed plantations of indigenous tree species (P), and abandoned pastures (G), at both the flooding areas (V) and the sloping (M) of the Reserve. Soil analysis were collected at the layers 0-2.5cm; 2-5-7.5cm; and 7.5-20cm to evaluate soil pH, and the contents of Al, Ca, Mg, P, K, C and N. The PV treatment showed higher values for soil Ca, Mg, K, C and soil organic matter (SOM), indicating high cycling rates and biological activity. Soil stability was found to be high in all treatments, since C:N ratio was lower than 12:1. Organic matter fragmentation showed a higher amount of fulvic acids (FA), humic acids (HA) and humins (HU) in the PV treatment, for the three soil layers. The plantation on the hillside (PM) had the highest values of (FA+HA)/HU ratio, suggesting a lower stability condition. The extraction-fumigation method was used to estimate C and N contents in the soil microbial biomass (MB), as well as the soil respiration rate, only for the 0-2.5cm layer. There was no difference in C-MB (Cmicr.) and N-BM (Nmicr.) values among the treatments, but both metabolic quotient (qCO2) and Cmicr.:Nmicr. ratio was higher for the PM, which may suggest a less stable site than those on the flooding areas. The structure of edaphic fauna indicated higher fauna density in the flooding area Forest (FV), but PV showed an average group richness similar to those of Forest sites, despite PM groups richness was similar to those of pastures. In order to evaluate forest regeneration mechanisms, soil seed bank and seed rain were monitored. The PV treatment showed more seedlings (381) and more species (25) emerging from the soil samples, and the hillside plantation (PM) trapped the highest amount of seeds, mostly from Gochnatia polymorpha, a typical pioneer tree species. Results suggest that restoration techniques to be adopted must be specific for either the sloping sites or the flooding areas. The establishment of Forest connectivity may enhance the participation of tree species in seeds and fruits dispersal events. |

O uso de par?metros ecol?gicos como indicadores teve o objetivo de avaliar a restaura??o de ?reas degradadas na Reserva Biol?gica de Po?o das Antas, RJ. Esse estudo envolveu ?reas de floresta madura, plantios mistos de esp?cies arb?reas nativas com 8 anos de vida e pastagens abandonadas nas v?rzeas e morrotes da Reserva. Foram avaliados o pH do solo, os teores de Al, Ca, Mg, P, K, C e N do solo, para as profundidades de 0-2,5cm; 2- 5-7,5cm; e 7,5-20cm. Os plantios da v?rzea apresentaram teores de Ca, Mg, K, C e mat?ria org?nica do solo (MOS) superiores aos dos outros tratamentos, indicando o r?pido estabelecimento de altas taxas de ciclagem de nutrientes e alta taxa de atividade biol?gica. A estabilidade do solo foi alta para todos os tratamentos, que apresentaram rela??o C:N abaixo de 12:1. Para estimar a forma como a MOS est? armazenada foi feito o seu fracionamento qu?mico, que apontou maior produ??o de ?cidos f?lvicos (AF) e h?micos (AH), e huminas (HU) no plantio de v?rzea, para as tr?s profundidades de solo citadas. O plantio no morrote apresentou maiores valores da rela??o (AF+AH)/HU, o que sugere uma menor estabilidade nesse tratamento. Pelo m?todo de fumiga??oextra??o foram estimados tamb?m, somente na camada de 0-2,5cm, os estoques de C e N na biomassa microbiana do solo (BMS), bem como a taxa de respira??o no solo. N?o houve diferen?a significativa entre os tratamentos para BMS-C e BMS-N, mas valores mais altos do quociente metab?lico (qCO2, que mede a efici?ncia na utiliza??o de C pela BMS) e da rela??o BMS-C:BMS-N para o plantio de morrote refor?a a hip?tese desse tratamento ter uma menor estabilidade que o plantio da v?rzea. A an?lise da estrutura da fauna de solo, que avaliou a atividade de grupos com o uso de armadilhas do tipo pitfall, mostrou que a riqueza m?dia de grupos no plantio da v?rzea se assemelhou ? das ?reas de floresta, enquanto a do plantio do morrote foi similar ? das pastagens. Para se avaliar mecanismos relacionados ? regenera??o natural da floresta, foram avaliados a chuva de sementes e o banco de sementes do solo. O plantio de v?rzea foi o tratamento com maior n?mero de pl?ntulas (381) e esp?cies (25) no ensaio de banco de sementes, e o plantio do morrote foi o tratamento com maior n?mero de prop?gulos, com maioria de Gochnatia polymorpha. A an?lise multivariada dos resultados sugere que os par?metros relacionados ? mat?ria org?nica do solo s?o maiores para as ?reas de v?rzea, e que as t?cnicas de restaura??o sejam diferentes entre ?reas de morrote e de v?rzea. A instala??o de corredores de vegeta??o que restabele?am a conectividade entre os fragmentos florestais da regi?o pode aumentar participa??o de esp?cies arb?reas nos processos de dispers?o.Made available in DSpace on 2016-04-26T19:39:27Z (GMT).

Mixed plantations of indigenous tree species have been widely used in the restoration of degraded Atlantic forests which had been converted to pastures. This study used ecological indicators to evaluate the status of restoration in mixed plantations at the Po?o das Antas Biological Reserve, Southeastern Brazil. Study sites involved mature forests (F), 8-year-old mixed plantations of indigenous tree species (P), and abandoned pastures (G), at both the flooding areas (V) and the sloping (M) of the Reserve. Soil analysis were collected at the layers 0-2.5cm; 2-5-7.5cm; and 7.5-20cm to evaluate soil pH, and the contents of Al, Ca, Mg, P, K, C and N. The PV treatment showed higher values for soil Ca, Mg, K, C and soil organic matter (SOM), indicating high cycling rates and biological activity. Soil stability was found to be high in all treatments, since C:N ratio was lower than 12:1. Organic matter fragmentation showed a higher amount of fulvic acids (FA), humic acids (HA) and humins (HU) in the PV treatment, for the three soil layers. The plantation on the hillside (PM) had the highest values of (FA+HA)/HU ratio, suggesting a lower stability condition. The extraction-fumigation method was used to estimate C and N contents in the soil microbial biomass (MB), as well as the soil respiration rate, only for the 0-2.5cm layer. There was no difference in C-MB (Cmicr.) and N-BM (Nmicr.) values among the treatments, but both metabolic quotient (qCO2) and Cmicr.:Nmicr. ratio was higher for the PM, which may suggest a less stable site than those on the flooding areas.
