Intercropping of trees and annual crops could be an important alternative for promoting forest restoration in small farms. The objective of this study was to evaluate the intercropping of cassava (Manihot sculenta Crantz) with native trees for restoration of natural forest in riparian areas in the western São Paulo State, Brazil. The experimental design was randomized blocks with six replications for comparing two restoration systems: pure afforestation and afforestation intercropped with cassava. It was evaluated the variables related to seedling development (height, crown diameter, crown cover, and height/crown diameter ratio), mortality and the economic impact were assessed for using cassava. No differences were found between treatments for any dendrometrical variable and mortality. Economic impact of the intercroppoing treatment was positive because costs for establishment of intercropped system were partially reduced by the income from the cassava crop, which covered 32% of total costs. Cassava income made final costs 19% lesser than restoration in the pure afforestation system.

The objective if this work was a survey of medicinal plants plus commonly cultivated in quintais in Amazon State, Brazil. The work was carried out in five counties at the Solimões/Amazonas and Negro Rivers, by questionnaires, interviews and collections of botanical materials, using the literature to define the geographic origins. It was showed 105 species of medicinal plants, with average of 13 per house. The Amazonian plants, in general wood plants, meaning 10,9 percent of the total of species that was survey, with predominance of the American continent plants out of Amazonian (38,2 per cent). The major group was herbaceous or shrubs exotic plants, aromatics. In general, the peoples unknown the origin of the species of medicinal plants that use day after day.
