Scientific Name: Allium iatrouinum Trigas
Taxonomic Source(s): Trigas, P., Kalpoutzakis, E. and Constantinidis, T. 2017. Two new Allium (A. sect. Cupanioscordum, Amaryllidaceae) species from Greece. Phytotaxa 297(2): 179-188.

Assessment Information [top]

Red List Category & Criteria: Critically Endangered B1ab(iii,v)+2ab(iii,v); C2a(ii) ver 3.1
Year Published: 2017
Date Assessed: 2017-03-10
Assessor(s): Trigas, P. & Constantinidis, T.

Justification:
This species is currently known only from the type locality (Mt. Ochi, Kerasia summit, in the southern part of Evvia Island, Greece. It is currently known to be distributed along the ridge that connects Kerasia summit with a lower peak to the west, however it is possible that the species has a wider distribution in the area of Cape Kafireas (Cavo d’Oro). The species is known to occur in 23 clusters of individuals, with an estimated population size of ca 200-400 mature individuals. Although the known population is within a Natura 2000, numerous wind parks have been developed in the area, and wind turbines are currently under construction within the distribution area of this species. Further research is required to confirm the distribution of this species, and the impact of the wind park development on the known population. Both the extent of occurrence (EOO) and the area of occupancy (AOO) are estimated at 4 km², however the actual impacts of the wind farm development is not known, and we can not say if there is a continuing decline in EOO, AOO, population size or habitat quality. The species is assessed as Critically Endangered (CR B1ab(iii,v)+2ab(iii,v); C2a(ii)) on the basis of a restricted EOO and AOO, with projected declines in habitat quality and number of mature individuals. The species would likely also qualify, if data were available, for CR under criteria A3 or A4 (population reduction) as the expected impacts of the wind farm development along the ridge where the known population occurs are expected to be severe.

Geographic Range [top]

Range Description:This species is currently known only from the type locality (Mt. Ochi, Kerasia summit, c.10 km N-NE from the town of Karistos) in the southern part of Evvia Island in the west Aegean, Greece. The species is distributed along the ridge that connects Kerasia summit with a lower peak to the west, however it is possible that the species has a wider distribution in the area of Cape Kafireas (Cavo d’Oro). The mountainous area of Cape Kafireas is not easily accessible and its flora remains poorly explored (Trigas et al. 2017).

Population [top]

Population:Within the small currently known extent of occurrence, 23 clusters of individuals were counted and the estimated population size is about 200-400 mature individuals.
Current Population Trend:Stable
Additional data:

Habitat and Ecology [top]

Habitat and Ecology:The species grows in crevices of metamorphic rocks at 1,000–1,050 m a.s.l. It flowers from the end of June to the end of July. The plants grow in clusters and form groups of c.10–20 individuals. The whole area is exposed to strong north winds, especially during the summer. The accompanying taxa of are, amongst others, Inula candida subsp. limonella, Cerastium candidissimum, Ballota acetabulosa, Thymus longicaulis subsp. chaubardii and Ornithogalum narbonense (Trigas et al. 2017).
Systems:Terrestrial
Continuing decline in area, extent and/or quality of habitat:Yes

Use and Trade [top]

Use and Trade: The species is not known to be utilised.

Threats [top]

Major Threat(s): Although the known population is within a Natura 2000, numerous wind parks have been developed in the area, comprising several hundred individual wind turbines. A wind park is currently under construction in the distribution area of this species and threatens with extinction the only known population of the species.

Conservation Actions [top]

Conservation Actions: It is assumed that additional populations of this tiny, late flowering species will be found in neighbouring areas and further fieldwork is required to confirm its distribution. The distribution area of A. iatrouinum is included in the protected area of the Natura 2000 network “Oros Ochi–Kampos Karystou–Potami–Akrotirio Kafirefs–Paraktia Thalassia Zoni” (GR2420001).
