Within the family Magnoliaceae Juss., the genus Magnolia L. has the largest number of species, including more than 300 species worldwide, whose number is increasing due to the recent discovery of new species, mainly in the Neotropical region. The group is mainly represented by trees that are usually represented by a few records in herbariums. Determining the conservation status of Magnolia species is a challenge, since of the 75 species in South America, 59 are threatened according to IUCN threat categories. However, as the species have been assessed for several years, there is a need to know the current conservation status, update this assessment, and provide information for those species with deficient data. The objective of this lecture is to discuss these strategies to update the conservation status of Magnolia species in South America, especially in Brazil, so that we can contribute to the effective conservation of this interesting group of plants characterized by vulnerable populations, especially in the face of climate change scenarios. There are many species of Magnolia in America that are threatened with extinction and are included in the IUCN Red Lists. However, numerous species lack information and need studies to compensate for their threatened status. The consolidation of this information in the different countries of South America provides important decisions in the field of public policies that can help in the maintenance of Magnolia species. The importance of the Global Conservation Consortium for Magnolia is highlighted, engaged in the dissemination and construction of effective collaborative work in the conservation of these plants. For Brazil, only the following species are considered: Magnolia amazonica (Ducke) Govaerts, Magnolia grandiflora L.; Magnolia ovata (A.St.-Hil.) Spreng.
