Mesures de conservation recommandéesStratégies de conservation IUCNExpert

The genus Aegilops is listed in Annex I of the International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA) as part of the wheat gene pool.

There are 44 germplasm accessions of wild origin reported by Genesys of which 22 are backed up at a second genebank. Furthermore, eight accessions are duplicated and conserved ex situ in the Svalbard Seed Vault. Out of the 44 accessions, 20 were collected within the species' native range (eight from Iraq, six from Uzbekistan, Turkey, three from Turkmenistan, two from Iran and one from Syria). A further seven accessions were collected from outside the species' known native range (four from Turkey, two from Kazakstan and one from Japan) and 17 are of undisclosed country of origin (Genesys Global Portal on Plant Genetic Resources 2017).

According to Botanic Gardens Conservation International (BGCI 2013), this species has living collections in four botanical gardens worldwide, although the origin and location of the collections are not detailed in this resource (garden locations are undisclosed to protect rare and valuable plant species).

Diversity and gap analyses are also needed to inform future in situ and ex situ conservation actions.
