Evaluation of the Conservation Status of Threatened Lichens List from Coastal areas of the Valencian Community (Eastern Spain)

The current conservation status of populations of eleven threatened lichens from coastal areas of the Valencian Community is analysed. Maps and current known distribution are also provided. Randomly selected threatened lichen populations have been quantitatively studied by counting the number of individuals and estimating the area of substrate colonisation for future surveys. Present, projected or suspected decline in populations of these lichen species is noticed by inspection of their habitats. Most of the threats found are due to human activity in the form of urbanism and fires. With this information in mind, the IUCN categories and criteria were reassigned to the lichen species. Future perspectives of these populations are speculated according to present day habitat conservation and management.
