| Popis: | Categorization of risk of extinction of Dyckia limae L. B. Sm. and Tillandsia catimbauensis Leme, W. Till & J. A. Siqueira by geographical criteria. Geographical distribution criteria are good alternatives for the categorization of endangered species that are little known scientifically. The aim of this study was to use these criteria to categorize the species Dyckia limae L. B. Sm. and Tillandsia catimbauensis Leme, W. Till & J. A. Siqueira, which are endemic to Valley National Park Catimbau (PARNA Catimbau), D. limae and T. catimbauensis. Their extent of occurrence and area of occupancy were measured and the dispersion sites weighted with respect to the state of conservation. The extent of occurrence of D. limae and T. catimbauensis was respectively 15.1 and 22.1 km², while their area of occupancy was 5 and 8.5 km². In view of these values, along with the conservation conditions of the locality, the species fall under the category of “Critically Endangered.” |
