Composição, uso e conservação de espécies arbóreas em quintais de agricultores familiares na região da mata seca norte-mineira, Brasil
Homegardens contain agroforestry systems that provide diverse resources for familyconsumption in rural communities. The aim of this study was to perform an ethnobotanical inventory of the tree speciesand their uses in the homegardens of two small-scale rural farming communities situated near the Mata Seca State Park,Minas Gerais, Brazil, and to understand the potential role of these agroecosystems in the conservation of native treespecies. Local knowledge about species used was assessed using free lists with 20 small-scale farmers selected using thesnowball sampling technique in each community. All shrub and tree species with a circumference at the soil level 10 cmwere sampled in each homegarden. We confirmed that most plant species listed provided food (48.3%) and shade (35.6%),showing the importance of fruit trees and evergreens in the homegarden flora in this local semi-arid context. Other specieswere also cited as medicinal and ornamental plants. Besides that, some species listed were used for construction, fuel,fodder, fertilizer and other uses. Amongst the 87 tree species, 44 are Brazilian natives, and 23 can be found in the dryforests of the region. These results showed that homegardens can contribute to conservation and enhancement of localbiodiversity functioning as a reservoir of species with different biogeographic origins, including regionally endemic andnative trees. Furthermore we conclude that homegardens are important sources of plant resources for home consumptionand contribute towards a balanced diet and to the welfare of the people living in the communities of north Minas Gerais’semi-arid region.
