| Popis: | Generally, works of public interest, such as the construction of hydroelectric power plants cause changes in ecosystems. Compensation for damage shall be notified by the entrepreneur, through ecological restoration of degraded ecosystem. Thus, the present study was designed to evaluate the evolution of areas in restoration process for a forest remnant more preserved, as well as evaluating methods and potential species, capable of maintaining the functionality of ecosystems. The State Park Quarta Colônia is full protection unit of 1847 hectares, located in the municipality of Agudo and Ibarama, Rio Grande do Sul, established in 2005, as a compensatory measure to the work of the hydroelectric dam of Dona Francisca, Rio Grande do Sul. The work was developed in chapters, where initially, held the definition and characterization of the reference area, establishing parameters for comparison with the areas in process of restoration. The reference area is located near 555.82 m of reclaimed areas, and 615.33 m of another, is composed of secondary forest in middle to advanced stage of succession. The vegetation of the reference area was recorded using 10 x 20 m 12 plots (200 m²) on tracks 100 m apart between sí, and 20 m between plots distributed systematically by topography gradient, being held at the circumference measurement of height peiro (CAP) of all individuals and arboreal with CAP ≥ 15 cm arbustivos. The regeneration was measured in circular sub-plots with radius of 1.78 m (10 m2) in the center of the parcels, and individuals with height ≥ 30 cm and CAP |
