RESUMO

This study was conducted at the Pontal do Paranapanema Region, State of São Paulo. This region is well known for its landless conflicts and, at the same time, environmental degradation. The Pontal region harbors the last remnants of the Brazilian Atlantic Forest, including the 37.000 ha Morro do Diabo State Park and other surrounding forest fragments isolated in the landscape. Facing this scenario we need to develop landscape restoration plans for conserving the remaining biodiversity. One of the possible alternatives is the restoration of landscape corridors with agroforestry tools. The objective of this study was to evaluate the potential of a leguminous species (Cajanus cajan (L.) Millsp.) as a catalyzing specie for the native forest restoration. I analyzed four experimental plots with different densities of Cajanus cajan, intercropped with native species and annual crops. The results suggested that Cajanus cajan is a good catalyzing species that enhances the growth and the development of the forest species. Cajanus cajan can be used as a intercropping species in forest restorations programs since it has the potential of maintaining soil humidity, organic matter, windbreaks, nitrogen fixing and criating “safe sites”. The results confirm the hypothesis that some leguminous shrubs can be used as potential catalyzing species for forest restoration in the three starting years of restoration.
