A eficiência conservacionista de medidas de recuperação de áreas degradadas: proposta metodológica

Ecological evaluation of some land reclamation techniques: a methodological approach. The study of land reclamation is now intensive in Brazil, mainly in relation to the rehabilitation processo Usually, the methodology utilised are based in theory and combine different aspects: environment response and philosophical point of view from different work groups. Then, the environment results obtained are diverse and difficult to be compared. The subject of this study is to suggest new ways to evaluate the conservation efficacy of a variable used in land reclamation projects. We suggest the utilisation of a spontaneous establishment of plants, as a biological indicator in the environmental recovery of degraded area. The idea was constructed with results obtained in a land reclamation area since 1993, in which an average of 13m of soil profile was removed.
