European regional assessment: Data Deficient (DD)
Avena volgensis is a specialized weed of a local landrace of Triticum dicoccum. This landrace has been replaced with commercial varieties since the 1950s and the population of this weed has therefore declined dramatically. It is suspected that the species faces a high risk of extinction; however, in order to assess it, more information on the rate of decline in the last ten years or the actual area of occupancy is needed. It is therefore assessed as Data Deficient.
It does not occur within the EU 27.
|Range Description:||Endemic to Central and Eastern European Russia (Valdés and Scholz; with contributions from Raab-Straube and Parolly 2009).|
Native:Russian Federation (Central European Russia, East European Russia)

|Population:||The population of this species is in severe decline. It has probably declined by 80% since 1950.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||It is found in agricultural land where it is a specialized weed of a local landrace of Triticum dicoccon.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Use and Trade:||A wild relative of and potential gene donor to oats, A. sativa and A. byzantina (Maxted et al. in prep.).|
|Major Threat(s):||It is threatened by the replacement of landraces with commercial crops.|
The genus Avena is listed in Annex I of the International Treaty on Plant Genetic Resources for Food and Agriculture.
No germplasm accessions of A. volgensis are reported by EURISCO to be held in European genebanks (EURISCO Catalogue 2010). The ex situ conservation status of this species needs to be determined.
Information on the population size, distribution and trend in the last ten years is needed.
