Diversity of chasmophytes in the vascular flora of Greece: floristic analysis and phytogeographical patterns
Cliffs are among the environments with the most adverse conditions for living organisms because of the limited availability of soil, moisture, and nutrients, and owing to the harsh conditions of exposure. They constitute shelters for rare, endemic, and range-restricted plant taxa. A main database ha...

Cliffs are among the environments with the most adverse conditions for living organisms because of the limited availability of soil, moisture, and nutrients, and owing to the harsh conditions of exposure. They constitute shelters for rare, endemic, and range-restricted plant taxa. A main database has been prepared which includes vascular plant taxa that are obligate or facultative chasmophytes and also contains information about their life form, chorology, protection status, occurrence in more than 135 places such as cliffs, gorges, or open rocky habitats, and their geographical distribution in the 13 phytogeographical regions of Greece based on available floristic, vegetation, and phytosociological literature and on the authors' own collections and observations. The paper presents an analysis of the total diversity of cliff plant species, as well as the diversity of obligate chasmophytic plant species, endemics, and range-restricted taxa, in addition to the results of studying the distribution patterns of different subsets of plant taxa in the different phytogeographical regions of Greece.
