Abstract
This study aimed to assess the effectiveness of four weed control strategies in forest setting stands linked by a set of Atlantic Forest tree species. Four treatments were employed: mechanical ? manual hoeing and mowing; chemical ? glyphosate herbicide application in the total area; chemical ? cultural ? herbicide spraying and herbaceous legume intercropping; chemical-mechanical ? herbicide planting in rows and mowing in the interrows. Diameter, crown area and soil cover percentage of the eight tree species were assessed at 18 months. Herbicide spraying in total area promoted the greatest reduction in weed populations, as well as superior growth in height, diameter, crown area and soil cover of the tree species. More interventions were necessary in the treatment of mechanical weed control that has also shown the least growth of the tree species. The chemical method was the most effective in weed control and promoted the greatest growth of the tree specie

Summary
Natural landscape has been reduced in many parts of the world to withstand different human activities. In the period between 1990 to 2015, according to Morales-Hidalgo et al (2015), primary forest areas declined 2.5% globally and up to 10% in tropical areas. In this context, the Brazilian Atlantic Forest is inserted as a widely degraded landscape, with forest remnants mostly dominated by small fragments. Reckoned the noteworthiness of restoring these areas, many countries have been seeking out measures to secure restoration and maintenance of natural landscapes. To achieve this goal, forest restoration emerges as one of the main strategies. As underlined by Martin (2017), the restoration process seeks to help in recovering degraded, damaged or destroyed ecosystems to ensure the survival of organisms and to provide goods and services to humans
