Kingdom Phylum Class Order Family
Plantae Tracheophyta Liliopsida Asparagales Amaryllidaceae

Scientific Name: Allium lopadusanum Bartolo, Brullo & Pavone
Taxonomic Notes: Allium lopadusanum Bartolo, Brullo & Pavone is a tertiary wild relative of a number of crops in the allium group, including onion (A. cepa L.), Welsh onion (A. fistulosum L.), leek (A. porrum L.), garlic (A. sativum L.) and chives (A. schoenoprasum L.). It shows some relationships with A. lojaconoi from the Maltese Islands and belongs to Allium sect. Brevispatha (Bartolo et al. 1986).

Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2011
Date Assessed: 2010-04-12
Assessor(s): Branca, F. & Donnini, D.
Reviewer(s): Dulloo, M.E., Nieto, A. & Kell, S.P.
Contributor(s): Kell, S.P.
Justification:
Allium lopadusanum is a rare species endemic to Lampedusa in Sicily, which covers and area of 25 km2. It was classified as Rare in the 1997 IUCN Red List of Threatened Plants (Walter and Gillett 1998) and as Endangered in the Liste Rosse Regionali delle Piante d'Italia (Conti et al. 1997), which means it was considered to be at risk more than 10 years ago. However, the precise extent of occurrence (EOO) and area of occupancy (AOO) is unknown and further research is needed to gather information about its habitat, population size and trend, potential threats and its in situ and ex situ conservation status. It is therefore assessed as Data Deficient.

Use and Trade [top]

Use and Trade: It 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): Further research is needed to gather information about the main threats to this species; however, it is thought that it could be affected by pesticide use.

Conservation Actions [top]

Conservation Actions: It is listed as Endangered (EN) in the Liste Rosse Regionali delle Piante d'Italia (Conti et al. 1997) and in the 1997 IUCN Red List of Threatened Plants (Walter and Gillett 1998) as Rare (R) (not Endangered or Vulnerable, but at risk).

No germplasm accessions of A. lopadusanum 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.

It occurs in a protected area.
