Sicilian fir
threatened species - Opis:
- In the mountains of the north-central Sicily (Italy), a small and isolated population of Sicilian fir (Abies nebrodensis) has survived to the present day. It is the most unique species of the Sicilian flora, not only because of its taxonomic position, but mostly because of its endemic and relict status and the serious risk of extinction. The single natural population of this extremely rare species is currently represented by only 30 mature individuals scattered over a small area in the Madonie Mountains. This species has experienced intensive population decline since the end of the 17th century, and its situation became extremely critical in the first decades of the 19th century due to deforestation and overgrazing. Consequently, Sicilian fir was considered to be extinct about three decades before being rediscovered on the Madonie Mts. in 1937. Sicilian fir is recognized as one of the most endangered coniferous species in the world. It is classified as critically endangered by IUCN, and also included in the list of 50 most endangered plant species in the Mediterranean region. Currently, the limited population size, a small proportion of reproductive individuals, habitat loss, ongoing and projected climate change, and hybridization with other species pose serious threats to survival of this species. Therefore, it is extremely important to maintain actions focusing on in situ and ex situ conservation in order to preserve and protect the existing resources of Sicilian fir, which represents the natural heritage unique to the Mediterranean.
