Allium pyrenaicum is assessed as Vulnerable because its extent of occurrence (EOO) is less than 20,000 km2, its area of occupancy (AOO) is less than 2,000 km2, its distribution is severely fragmented, and there is a continuing decline in the extent and quality of its habitat due to livestock grazing and forest enlargement.

Geographic Range [top]

Range Description: A. pyrenaicum is endemic to Spain, where is grows in the east Pyrenees in the provinces of Gerona and Huesca (Mathew 1996). According to Aedo (in prep.) it also occurs in Navarra. Its extent of occurrence (EOO) is less than 20,000 km2 and its area of occupancy (AOO) is less than 2,000 km2.

Population [top]

Population: The population is scattered. In Catalonia there are 25,000 mature individuals (Oliver 2008), with an area of occupancy (AOO) of 33 km2. There seems to be three subpopulations in Aragon.
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: It grows in forest margins, rocky areas, badlands and on roadsides from 690–1,290 m asl (Aedo in prep.). It flowers from June to July (Mathew 1996).
Systems: Terrestrial

Use and Trade [top]

Use and Trade: A. pyrenaicum is a tertiary wild relative of and potential gene donor to a number of crops in the allium group, including onion (A. cepa), Welsh onion (A. fistulosum), leek (A. porrum), garlic (A. sativum) and chives (A. schoenoprasum).

Threats [top]

Major Threat(s): Livestock grazing and forest enlargement are major threats to this species.

Conservation Actions [top]

Conservation Actions: In Aragon and Catalonia, A. pyrenaicum is considered Vulnerable (D. Draper pers. comm. 2010). It is listed in the Lista Roja 2008 de la Flora Vascular Española (Moreno 2008) as Near Threatened (NT).

It occurs in protected areas; however, grazing management is needed to protect this species and a monitoring program should be implemented.

No germplasm accessions of A. pyrenaicum are reported by EURISCO to be held in European genebanks (EURISCO Catalogue 2010). A review of the ex situ conservation status of this species is required and germplasm collection and duplicated ex situ storage should be carried out as necessary.
