The invasion of non-native species is one of the main threats to biodiversity conservation and the provision of ecosystem services. Mangroves are one of the most vulnerable ecosystems worldwide due to invasive alien species (IAS), as they can destabilize the structure and function of trophic webs and reduce their primary productivity, mainly through competition and predation of native species. In this paper, an analysis of biodiversity information systems and scientific literature were used to determine the presence of IAS within the mangrove forests of the Ria Celestún and Ría Lagartos biosphere reserves in the Yucatan Peninsula, Mexico; the level of risk of IAS was identified according to the rapid invasiveness assessment method, and information was generated on the implications of IAS in mangrove forests. In both natural protected areas (NPAs), 16 IAS were found, of which 56.25% had a "very high" invasiveness risk value, and 43.75% had a “high” invasiveness risk, which implies a danger alert for mangrove forests in the NPAs. The information generated in this study can be used to identify strategies for managing IAS and the conservation of mangrove forests in NPAs.
