Zusammenfassung: | Sao Paulo city has three municipal nurseries for the distribution of urban tree specimens that meet the demand for its public landscape projects and increase in tree covering. One of them (Manequinho Lopes) receives tree seedlings from the environmental compensation processes contracted with the Municipal Secretariat for Green and Environment (MSGE). This paper aimed to evaluate the scenario of tree biodiversity received between July 2013 and July 2018 by the Manequinho Lopes nursery, as a measure of environmental compensation. The results indicated that 144,727 tree seedlings were received by the nursery, with approximately 80% of the total belonging to only 30 species, half of them belonging to only 10 different groups. We found just two predominated families: Myrtaceae and Bignoniaceae, highlighting a biotic homogenization risk. Regarding ecological attributes, it was found that 33% of the species were zoochoric, 16% autochorous and 22% anemochoric. Most of them were non-endangered specimens. Keywords: Green areas; Native species; Green infrastructure; Environment; Nurseries A cidade de Sao Paulo possui tres viveiros municipais de distribuicao de exemplares de plantas que atendem a demanda de seus projetos paisagisticos e o aumento da cobertura arborea. Um deles (Manequinho Lopes) recebe mudas de arvores pelos processos de compensacao ambiental contratados pela Secretaria Municipal do Verde e Meio Ambiente (SVMA). Este trabalho teve como objetivo avaliar o cenario da biodiversidade arborea recebida entre julho de 2013 e julho de 2018 pelo viveiro Manequinho Lopes, como medida de compensacao ambiental. Os resultados indicaram que 144.727 mudas de arvores foram recebidas pelo viveiro, com aproximadamente 80% do total pertencendo a apenas 30 especies, sendo que metade delas pertencem a apenas 10 grupos diferentes. Encontramos apenas duas familias predominantes: Myrtaceae e Bignoniaceae, evidenciando o futuro risco de homogeneizacao biotica. Em relacao aos atributos ecologicos, constatou-se que 33% das especies eram zoocoricas, 16% autocoricas e 22% anemocoricas. A maioria deles eram especimes nao ameacados de extincao.
