Helianthemum polygonoides, classified as "Critically Endangered", has a single known population in the world, within the SAC "Cordovilla and Agramón Saltmarshes and Alboraj Lagoon" (SE Spain), with a severely restricted distribution area. Its Recovery Plan establishes conservation and restoration actions, but there is a need to carry out periodic reviews of the conservation status of the species due to the different current environmental threats. Therefore, the goal of this study is to review the current situation of H. polygonoides, updating its distribution area, determining its current threats and establishing new guidelines for its conservation. In this framework, censuses have been carried out to estimate its distribution area in the field, disturbances that threaten the species have been detected, and, finally, an assessment of the protection and conservation measures described in the Recovery Plan has been carried out. The obtained results have shown H. polygonoides has an estimated distribution area of 15 ha and its population has risen to 381,909 individuals. Besides, the disappearance of some populations has been detected; and new areas of occupation of the species have been found in the SAC, as well as extensions of the tesserae previously described in the literature. The well-formed populations have been found in the optimal preserved areas and the densities of adult individuals are generally high. Finally, the current situation of the habitat is characterized by a remarkable fragmentation and degradation driven by numerous threats, which put the conservation of the species at risk and condition its current distribution. Thus, this study proposes new guidelines for action, being a necessary tool for the management and conservation of this exclusive endemism.
