Scientific Name: Fritillaria rhodocanakis Orph. ex Baker
Taxonomic Source(s): WCSP. 2017. World Checklist of Selected Plant Families. Available at: http://apps.kew.org/wcsp/.
Taxonomic Notes: Fritillaria rhodocanakis hybridizes with Fritillaria spetsiotica in the southern part of Argolida up to Poros Island, and with Fritillaria graeca at the north part of Argolida and at Korinthia. As a result, throughout its distribution on mainland Peloponnisos where it forms scattered, small population patches, F. rhodocanakis has variable populations with morphological characters intermediate between the different species.

Fritillaria rhodocanakis subsp. argolica is distributed in eastern Peloponnisos and is considered a hybrid of F. r. rhodocanakis and Fritillaria graeca as well as other species distributed in the Peloponnisos. For this assessment, only Fritillaria rhodocanakis subsprhodocanakis has been considered (P. Trigas pers. comm. 2016).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2017
Date Assessed: 2016-02-05
Assessor(s): Trigas, P. & Delipetrou, P.
Reviewer(s): Barrios, V. & Allen, D.J.
Contributor(s): Kamari, G.
Facilitator/Compiler(s): Barrios, V.
Justification:

This species is endemic to Greece, occurring in a very restricted distribution on Ydra (Hydra) Island and islets between Ydra and Argolida district, however it is considered rather common in several localities, populations are stable, and at present the known threats are not having significant impacts. It is assessed as Least Concern at present, however the species does not occur in protected areas, and monitoring of harvest, habitat and population trends is required.

Geographic Range [top]

Range Description:

This species is endemic to Greece, with unhybridized populations only found on Ydra Island and on islets between Ydra and Argolida district (e.g. Dokos Island and Petrothalassa Islet, although the identity of these records requires confirmation (P. Delipetrou pers. comm. 2017). This assessment refers only to Fritillaria rhodocanakis subsp. rhodocanakis, whilst subsp. argolica is distributed in eastern Peloponnisos and is considered a hybrid of F. r. rhodocanakis and Fritillaria graeca as well as other species distributed in the Peloponnisos, is excluded.

Population [top]

Population:The population of F. r. rhodocanakis has been estimated at about 300,000 individuals and is considered to be stable (P. Trigas pers. comm. 2016). The population on Dakos was very small (c.20 individuals) and restricted to a single ravine (Phitos et al. 2009) but it is not known if the island has been subject to resurvey.
Current Population Trend:Stable
Additional data:
Number of mature individuals:500
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species is found in rocky limestone areas with phrygana or low maquis and clearings as well as in the understorey of Pinus halepensis forest, at the edge of vineyards; it is usually in open vegetation but often under shrubs. It is found at altitudes of 10–500 m asl.
Systems:Terrestrial
Continuing decline in area, extent and/or quality of habitat:Yes

Use and Trade [top]

Use and Trade: Bulb collection is a threat since bulbs are widely cultivated and also sold on the internet.

Threats [top]

Major Threat(s): Tourism-related development and urban development may constitute a threat to to this species in a limited area around the town of Ydra, however it can be highlighted that this island has no vehicles and no major development plans are projected. Bulb collection can be an additional pressure. The species is not affected by fire. Hybridization does not seem to be a threat to this species due to its restricted distribution on an island with no other Fritillaria species and dispersal from the neighbouring mainland seems unlikely.

Conservation Actions [top]

Conservation Actions: This species is listed on Annex IV of the Habitats Directive and under Appendix I of the Convention on the Conservation of European Wildlife and Natural Habitats (Bern Convention). It is protected in Greece by Presidential Decree 67/81. It does not occur in protected areas. Monitoring of harvest, habitat and population trends is required.
