Mesures de conservation recommandéesStratégies de conservation IUCNExpert

There are 4 ex situ collections (BGCI 2021). This species was evaluated as threatened (EN) by the IUCN (Nelson 1998) and Vulnerable by the Red List of the Mexican Cloud Forest Trees (González-Espinosa et al. 2011). In Costa Rica, this species occurs in the National Park "Braulio Carrillo". In Guatemala, it is found in the Multiple Use Reservation "Cuenca del Lago Atitlan". In Mexico, it occurs in the Flora and Fauna Protection Area "El Jabalí" (Colima), and Biosphere Reserve "Los Tuxtlas" (Veracruz). It is recommended to set up sustainable production activities, livelihood alternatives to the destruction of forests, legal regulations, and conservation payments. Likewise, it would be beneficial to monitor habitat trends.
