dc.description.resumoDue to its coastal location, the Atlantic Forest has suffered from anthropogenic disturbances such as deforestation since the colonial period. Gradually the forest gave way to urban areas, pastures and agriculture. After the unbridled use of resources, the environment is faced with disturbances that hinder natural mechanisms of regeneration, therefore, forest restoration is necessary. Faced with so many challenges, this thesis aimed to contribute to the restoration of the Atlantic Forest in the Southeast of Minas Gerais, through three chapters: (1) Traditional knowledge about forest species: different times, different views; (2) Seed rain in chronossequence of restoration of the Atlantic Forest; (3) Exotic grass impairs the Atlantic Forest restoration in southeast Brazil. The reconstruction of the community as close as possible to the natural functional characteristics is a challenge, especially when it comes to areas distant from fragments talked about or old pastures that still have the presence of exotic grasses. The forest restoration projects are based on the areas discussed nearby, however, the term reference is based on the current floristics of the area and does not always take into account the primary forest that was installed before deforestation, so our first chapter confronts knowledge traditional and formal, based on lists generated by interviews with the elderly and young people and published lists. This chapter was developed in two areas with a different conservation history: Santa Teresa - ES a conserved area with high biodiversity and Aimorés - MG, an area that suffered from the exploitation of wood, flooding for the construction of a hydroelectric and railroad. Our results suggest that overexploitation in the past or the natural rarity of forest species are factors that justify the absence of species mentioned by the elderly population, as well as, we point out the importance of actions for the maintenance of traditional knowledge, with actions that motivate young people to acquire knowledge about vegetation today under the control of the elderly. The relevance of traditional knowledge was also highlighted, in addition to formal knowledge for the choice of species for forest restoration. To determine the success and succession of the restored area, there are standard variables analyzed, such as the replacement of species over time according to the ecological group and way of life. These patterns are verified through seed rain, so our second chapter sought to identify the response of seed rain in the face of environmental variables over a restoration chronosequence, we investigate the potential of the plant community over a restoration chronosequence by working in three areas aged 5, 10 and 20 years of restoration. We noticed a successional advance in 20 years through the composition of seed rain. In addition, the availability of light directly influences the seed rain. For the restoration of old pastures, there is still another challenge, the presence of exotic grasses with high competitive capacity and high seed production, therefore, verifying mechanisms that minimize the impact of exotic ones and collaborate with the establishment of native ones is also a factor that contributes with successful restoration. Therefore, in the third chapter we seek to evaluate the biotic and abiotic factors that act in the establishment of recruits in a conserved area and another in restoration, dominated by Urochloa brizantha. Our main finding suggests that the greater availability of resources in the area under restoration favors the high productivity of the grass, which also results in a high proportion of seeds in relation to forest species in the seed rain. Our results suggest that it is interesting to take advantage of traditional knowledge for planning actions to restore the Atlantic Forest. We also observed, based on the seed rain, signs of a positive trajectory in the restoration of the Atlantic Forest promoted by Instituto Terra. Among the difficulties of forest restoration in areas previously used as pasture, we verified that the availability of resources, mainly light, favors the growth and production of U. brizantha seeds, disfavoring restoration.pt_BR
