A preliminary evaluation of the conservation status of 54 Cuban endemic species of Polypodiopsida is presented; 14 are Critically Endangered (CR), 12 Endangered (EN), 9 Vulnerable (VU), 3 Near Threatened (NT) and 16 are Least Concerned (LC). The most common threat is the loss or degradation of the habitat because of agriculture, mining, deforestation and infrastructure development. Distribution and habitat are depicted.
