Pesquisa do estado de Minas Gerais (FAPEMIG)O presente estudo foi realizado com os seguintes objetivos: a) caracterizar o est?gio de degrada??o do solo com diferentes usos em ?reas de agricultores familiares no Vale do Mucuri; b) descrever a composi??o flor?stica de remanescentes de matas ciliares para subsidiar a recomposi??o das ?reas degradadas. Este trabalho faz parte do projeto n? 2008-3.08/07 Fapemig, em parceria com a ARMICOPA (Associa??o Regional Mucuri de Coopera??o dos Pequenos Agricultores). As amostras de solo foram coletadas em quatro localidades nos munic?pios de Ladainha, Novo Oriente, Pot? e Cara?, sendo que em cada localidade foram amostradas ?reas de pastagem, ?rea de cultura e remanescente florestal. Foram realizadas determina??es de atributos f?sicos, qu?micos e ligados ? mat?ria org?nica do solo de todas as ?reas. A composi??o flor?stica foi realizada nos quatro remanescentes florestais do bioma Mata Atl?ntica com Floresta Estacional Semidecidual. Foram alocadas nove parcelas de 10 x 10m, totalizando 900m? em cada ambiente de mata ciliar. O material bot?nico foi coletado dentro de cada parcela, sempre procurando atingir a maior diversidade poss?vel de esp?cies por fragmento. Dentre os agroecossistemas analisados, a mata foi a que apresentou melhor qualidade dos atributos do solo, o que indica que o uso e manejo influenciam diretamente sobre esses atributos. Nas quatro ?reas de mata ciliares foram identificadas 149 esp?cies, distribu?das em 81 g?neros e 40 fam?lias. Os resultados obtidos subsidiar?o a recupera??o desses ambientes com forma??o de sistemas agroflorestais, uma vez que a microrregi?o do Vale do Mucuri carece de estudos quanto ?s possibilidades de uso sustent?vel.Disserta??o (Mestrado) ?

This work takes part of the project n?00 Fapemig in partnership with ARMICOPA (Mucuri Regional Association for Cooperation to Small Farmers). The soil samples were collected in four areas of the municipal districts of Ladainha, Novo Oriente, Pot? and Cara?, considering that in each place there were collected samples of pasture, culture and remnant forest areas. Determination of physical, chemical and linked to the organic matter of the soil attributes was accomplished in all areas. The floristic composition was accomplished in four remnant forests of Atlantic forest with Seasonal Semidecidual Forest bioma. Were allocated nine 10 x 10m portions, totaling 900m? in each ciliary forest environment. The botanical material was collected in each portion always attempting to reach the largest species diversity possible per fragment. Among the analyzed agroechossistems, the forest was the one that presented better quality of the soil attributes, indicating that the use and handling can influence directly on those attributes. In the four ciliary forest areas 149 species were identified, distributed in 81 genders and 40 families. The results are aimed at subsidizing the recovery of those environments with agroforests systems developing, once the Mucuri Valley microrregion lacks of studies about the possibilities of maintainable use
