| This work aimed at identifying and quantifying colonizer species and structure in gravel mining degraded environment and to identify species for restoration. It was selected three sites characterized as: site 1 (S1), place with less intense history of use; site 2 (S2), intermediary level of degradation; and site 3 (S3), with higher degradation. Within the three sites it was withdrawn 20 plots of 25 m². Within each plot, species with height ≥ 0.10 m and DNS ≤ 5.0 cm were sampled. It was calculated Shannon’s diversity (H’), Pielou’s equability (J’), Jaccard’s and Czekanowski’s similarity indices, as well as the phytosociology parameters, besides the analysis of indicator species. Thirty-two species and 15 families were registered. S1 was the most... |

| This study compared the forest planning of outgrower schemes projects with own areas of forestry companies’ areas. The total area of the companies was 41,178 ha distributed in 299 stands, and the outgrower areas were 2,445 ha distributed in 144 properties. The planning involved linear programming of areas in order to maximize the equivalent annuity (EA), under the condition (constraints) of a regulated structure at the end of planning. Two scenarios were evaluated: a) individual model – areas of outgrower schemes and companies in separate models, and b) single model – areas of outgrower schemes and companies in the same programming model. The EA difference of the individual to the single model was unfavorable to outgrowers, since it reduced its value by... |
