Although gypseous habitats are present in many regions of the world, where they host a highly diversified and specialized flora. Despite their relevance and global distribution, gypsum plant communities have received less attention than other plant communities sustained on special substrates. One of the main consequences of this oblivion is their under-representation on National Red Lists and other similar inventories, which are an essential tool when recognizing and promoting the importance of preserving vulnerable taxa and giving priorities to their conservation and management. Through this work, we are trying to assess this issue by gathering information on the conservation status of over 1200 gypsophilic taxa included in a global checklist. We aim to understand how well-protected these habitats are in terms of their inclusion in national laws or scientific reports. For further understanding, analyses by species affinity to gypsum and the extent of their distribution have been done, along with a comparison of the total number of protected taxa among geographic regions.
