Abstract: Ecological restoration plays a fundamental role in ecosystem integrity recovery from restoration of species richness and structure of plant communities. Thus, if the decision is for planting, the production of forest seedlings with high species richness subsidizes the success of this practice. The aim of this study was to analyze the richness of native tree species potentially produced in nurseries in Rio Grande Basin in Southern Minas Gerais State. The analysis was based on the Native Trees Catalogue of Minas Gerais, considering the species present in the phytogeographic subdomains of Upper Rio Grande, South Mantiqueira, Poços de Caldas Plateau and Northwest. For the analysis of species with potential to be grown in nurseries in the Basin, data from the national register of seed and seedlings (RENASEM) from 2013 were used. It was found 1.251 species naturally occurring, 102 species indexed and 49 registered producers, distributed in 36 municipalities. Only five species listed in the official threatened species list were indexed by registered producers. The richness of tree species indexed by registered producers in RENASEM in the studied region is very low, which may compromise the success of ecological restoration projects.
