Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2011
Date Assessed: 2010-07-15
Assessor(s): Carta, A. & Peruzzi, L.
Reviewer(s): Abeli, T. & Bilz, M.
Justification:
Crocus etruscus is an Italian endemic that is found in central-southern Tuscany. It has an extent of occurrence of 1,892 km² and an area of occupancy of 120 km². The species occurs in isolated subpopulation nuclei but the populations are stable. However, the plant is potentially threatened by habitat degradation, predation by wild boar, and small-scale wood plantations. Crocus etruscus is therefore assessed as Near Threatened approaching Criterion B1a+2a.

Geographic Range [top]

Range Description:This Italian endemic is found in central-southern Tuscany, in the provinces of Grosseto, Livorno, Pisa and Siena. The major localities where the species is found are Monte Calvi (Livorno), Monte Leoni (Grosseto), Monte Amiata (Grosseto) and Massa Marittima (Grosseto). The species records for Isola d'Elba (Tuscany) and Emilia-Romagna are wrong and refer to C. ilvensis (Peruzzi and Carta 2011).

Systems:Terrestrial

Threats [top]

Major Threat(s): The plant is potentially threatened by habitat degeneration and reduction and by predation by wild boar (Sus scrofa). Small-scale wood plantations may threaten this plant in the future.

Conservation Actions [top]

Conservation Actions: Crocus etruscus 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).

The species is protected by law at the national and sub-national level. Research is being carried out into the taxonomy, population numbers and range, habitat status and threats. It is recommended that further research is carried out in these areas, together with a monitoring programme.
