Comprehensive Red List assessments act as valuable resources for informing protected area designations, national protected species legislation and action strategies, and international biodiversity agreements, yet they are lacking for many plant families. Magnoliaceae is one of the most comprehensively assessed families, as coordinated efforts have taken place since 2007 to assess all species in the family. Due to the many efforts to assess these species, comparisons of the assessments and ex situ data over time and an investigation of the most recent (2021) information are essential to guiding the development of national, regional, and global conservation strategies for Magnoliaceae species in a time of increased global collaboration between conservation organizations.
