“…During open-pit mining, layers are removed in a disorganized manner (Dias, 1998), which disrupts the characteristic soil horizons through inversion of layers, generating conic spoil heaps, with sedimentary rocks at the top of the pile and topsoil at the bottom (De Luca and Gastaldon, 1999). Consequently, there is loss of fertile soil, removal of vegetation, destruction of the seed bank, and decrease in the biodiversity of soil fauna, which directly affects soil functional characteristics (Sanchez and Formoso, 1990;Podgaiski et al, 2007;Citadini-Zanette et al, 2009;Klein et al, 2009). …”

Decomposition of leaf litter from pioneer tree species and development of associated soil meso-and macrofauna are fundamental for rehabilitation processes in reclaimed coal mining areas. The aim of our study was to evaluate decomposition of Schinus terebinthifolius and Senna multijuga to answer three basic questions: (i) What type of leaf litter degrades faster in reclaimed coal min\ing areas? (ii) Is leaf decomposition correlated with the stage of regeneration and exposure time? and (iii) Does the type of leaf litter influence the diversity and abundance of the soil meso-and macrofauna species collected? Experiments were carried out in the state of Santa Catarina in three areas at different stages of regeneration. A total of 32 litter bags (16 per plant species) were used per study site, and they were divided into four blocks along a transect. Sampling was carried out at 15, 30, 60, and 120 days, when one litter bag per species/block was removed at random. We found no statistically significant difference between S. terebinthifolius and S. multijuga in regard to leaf-litter decomposition rate. However, the "area", "litter bag exposure time" and "fauna richness" factors were significant. Therefore, shading and time of reclamation of areas contribute to an increase in decomposition rate and in development of soil meso-and macrofauna communities.

“…The spontaneous succession estimate (DR it [1], FR it [2] and RNC it [3]) of each species of any regeneration compartment was obtained by the following expressions (FINOL, 1971;VOLPATO, 1994;KLEIN et al, 2009). Where: RNC it = Estimate of natural regeneration of species i which belongs to a specifi c class t (%); DA it = Absolute density of species i which belongs to a specifi c class t; DR it = Relative density of species i which belongs to a specifi c height class t (%); FA it = Absolute frequency of species i that belong to a specifi c height class t; FR it = Relative frequency of species i that belong to a specifi c height class t (%); i = Subscript related to species; t = Subscript related to classes.…”

A Pilot Reclamation Project (PRP) was developed in 1982 by the Environmental Protection Agency of the State of Santa Catarina-Brazil, with the objective to evaluating the adaptation of woody species to a land degraded by coal mining. After a full topographic reconstitution of the landscape, addition of nutrient load and sowing of herbaceous species, the area was split into 12 plots in which seedlings of 12 tree species were planted: three native trees [Bastardiopsis densiflora (Hook. & Arn.) Hassl., Mimosa scabrella Benth., Schizolobium parahyba (Vell.) Blake] and nine exotic species [Eucalyptus saligna Sm., E. viminalis Labill., E. citriodora Hook., Grevillea hilliana F.Muell., Hovenia dulcis Thunb, Melia azedarach L., Pinus elliottii Engelm., P. taeda L., Syzygium cumini (L.) Skeels]. After 22 years, from the beginning of the PRP, the exotic species presented higher percentage of survival than native species; the plots which received either B. densiflora and S. parahyba or were covered only with herbaceous vegetation associated with solely a few shrubs. Conversely, the plots which received seedlings of M. scabrella displayed clear evidence of restoration in progress. The study conducted in plots that have received M. scabrella indicate an improvement of nutrient load (N, K, organic matter) in the substrate, a diversified composition of tree coverage (very similar to the nearby remnants of the Atlantic Rainforest) and other life forms, with prominent establishment of native trees with predominance of zoophilous and zoochorous species. Some characteristics of M. scabrella that could explain its outstanding capacity to enhance the restoration of the Atlantic Rainforest are also discussed along this paper. Mimosa scabrella BENTH. (FABACEAE) MELHORA A RESTAURAÇÃO EM ÁREAS DE MINERAÇÃO DE CARVÃO NA FLORESTA ATLÂNTICARESUMO: Um Projeto Piloto de Recuperação (PPR) foi desenvolvido em 1982 pela Fundação do Meio Ambiente do Estado de Santa Catarina -Brasil, objetivando avaliar a adaptação de espécies arbóreas em áreas degradadas pela mineração de carvão. Após uma completa reconstituição topográfica da paisagem, além da carga de nutrientes e sementes de espécies herbáceas, a área foi dividida em 12 pontos onde foram plantadas mudas de 12 espécies de árvores: três espécies nativas [Bastardiopsis densiflora (Hook. & Arn.) Hassl., Mimosa scabrella Benth., Schizolobium parahyba (Vell.)

Skeels]. Após 22 anos, as espécies exóticas apresentaram elevada taxa de sobrevivência em comparação com as espécies nativas; os pontos que receberem B. densiflora e S. parahyba foram cobertos apenas com espécies herbáceas associadas com alguns arbustos. Reciprocamente, os pontos que receberam mudas de M. scabrella demonstraram claras evidências no processo de restauração. O estudo conduzido em pontos que ...

A análise da distribuição diamétrica apresentase como uma útil ferramenta para o entendimento do nível de sucessão e conservação quem uma floresta se encontra. O presente estudo foi realizado em áreas de Floresta Ombrófila Mista sob histórico de sistema faxinal e uso e conservação distintos, localizadas em dois municípios paranaenses. Foram analisados todos os indivíduos arbóreos de DAP ≥ 10 cm em duas parcelas permanentes instaladas em Turvo-PR, sendo uma com 2 ha em sistema silvipastoril (FDSP) e uma de 1,8 ha em uma floresta secundária (FDSF) e quatro em sistema faxinal, localizadas em Rebouças-PR, identificadas sob as siglas FMB, FMC, FDS, FBB, todas com área de ha -1. Para a estrutura diamétrica, foram utilizadas 9 classes diamétricas com intervalo de 10 cm. A área FDSF apresentou maior densidade de indivíduos e de maior diversidade de espécies, enquanto que as demais áreas apresentaram menor densidade e riqueza. Todas as áreas de estudo apresentaram distribuição diamétrica em exponencial negativa ("J invertido") e DAP médio entre 26.8 e 19,8 cm, onde FMB e FDSP apresentaram indivíduos melhor distribuídos entre as classes de diâmetro, enquanto o FDS tem a grade maioria dos indivíduos concentrados nas classes de menor diâmetro. A análise da florística em conjunto com a distribuição diamétrica demonstrou que cada local apresenta características intrínsecas resultantes principalmente do grau de intervenção antrópica empregado em cada local.Palavras chave: Distribuição diamétrica, floresta com araucária, florestas manejadas. Diametric structure of six areas in faxinal of mixed ombrophilous rainforest AbstractThe analysis of the diameter distribution is presented as a useful tool for understanding the succession level and conservation who is a forest. This study was conducted in areas of Ombrophilous Mixed Rainforest under faxinal system history and distinct conservation and use, located in two Paraná municipal districts. Was analyzed all trees of DBH ≥ 10 cm in two permanent plots established in Turvo-PR, one with 2 ha in silvopastoral system (FDSP) and a 1.8 ha in a secondary forest (FDSF) and four in faxinal system located in Rebouças-PR, identified by the acronyms: FMB, FMC, FDS, FBB, all with an area of ha -1 . For the diameter distribution were used 9 diameter classes with an interval of 10 cm. The FDFS area has the highest density of individuals and greater diversity of species, while other areas had lower density and wealth. All study areas showed diameter distribution in exponential negative ("inverted J") and DBH average between 26.8 and 19.8 cm, where FMB and FDSP had better individuals distributed among diameter classes, while the FDS has the grid most individuals concentrated in the smaller diameter classes. The analysis of the flora in conjunction with the diameter distribution showed that each spot has intrinsic characteristics resulting mainly from the degree of human intervention used in each location.
