Cretan date palm description
| Kingdom | Plantae |
| Phylum | Tracheophyta |
| Class | Liliopsida |
| Order | Arecales |
| Family | Arecaceae |
| Genus | Phoenix (1) (2) |
Native to the eastern Mediterranean, the Cretan date palm (Phoenix theophrasti) is one of only two palm species endemic to Europe (4). This palm has a stem measuring up to 35 centimetres across (2), and a dense crown of long, spiky leaves, which become a striking silvery blue-green colour once mature (3) (5). These pinnate leaves can reach an impressive two to four metres in length (6), and have numerous forward-pointing leaflets 15 to 20 centimetres long on either side of the central stem (7) (8). The leaf stalks are heavily armed with long, yellow spines that are modified leaflets (2) (6), and when in bloom a mass of pale cream-coloured flowers emerge from among the leaf bases (6).

TopCretan date palm range
Eight subpopulations of Cretan date palms are found on the Greek Island of Crete, with the largest containing a few thousand individuals, and four subpopulations occur along the southwest coast of Turkey (1).

Cretan date palm status
The Cretan date palm is classified as Near Threatened (NT) on the IUCN Red List (1).
Cretan date palm threats
Evidence indicates that some populations of the Cretan date palm have substantially decreased or disappeared altogether. In the past, this palm was affected by the clearance of land for cultivation, but today, the greatest threats arise from tourism development. Even if the palm populations are not cleared for construction, they can be affected by the associated increased exploitation of underground water (4).
TopCretan date palm conservation
The largest subpopulation of the Cretan date palm on Crete is protected under Greek law (1).
