Floristic survey of the Furnas Gêmeas region, Campos Gerais National Park, Paraná state, southern Brazil

To investigate the resilience of the grassland flora of the Campos Gerais phytogeographic zone, this study surveys the phanerogamic plant species occurring in the Furnas Gêmeas area (Campos Gerais National Park, Paraná state,southern Brazil), especially those resilient to fragmentation by crops and fire. Collections were made monthly from October 2002 to May 2004 and occasionally from 2005 to 2013. In total, 313 species belonging to 70 angiospermsfamilies and 2 gymnosperm families were collected. Just 4 angiosperm taxa were not determined to species. Although the Furnas Gêmeas has suffered from very evident anthropogenic changes, the vegetation retains part of its original richness, as seen in better-preserved areas outside the park. Included in our list are endangered species that need urgent measures for their conservation
