With the term endemic species of plants or animals, we mean the species that exist and reproduce naturally only in one place and nowhere else. Their importance lies in the fact that they provide us with information about the past and the particular ecological factors of an area. They usually germinate in little soil, on steep rock crevices and they manage to survive in extreme weather conditions. Species under threat of extinction are the red lily and the white peony.
Moreover, 29 kinds of mammals have been recorded at Parnitha. Among them of special importance are the deer (Cervus elaphus), hares (Lepus europaeus), foxes (Vulpes Vulpes), badgers (Meles Meles), ferrets (Mortes foina), jackals (Canis aureus), squirrels (Sciurus vulgari), hedgehogs (Erinaceus concolor), etc.
The local bird population is especially remarkable as it is estimated that there are 120 different species of birds, endemic and migratory, such as Griffon vulture (Gyps Fulvus), Golden eagle (Aquila chrysaetos), Snake eagle (Circaetus gallicus), Peregrine falcon (Falco peregrinus), Rüppell’s warbler (Sylvia rueppelli) and Eagle Owl (Bubo bubo).
