Assessment Information [top]

Red List Category & Criteria:	Data Deficient ver 3.1
Year Published:	2011
Assessor/s:	Smekalova, T. & Maslovky, O.
Reviewer/s:	Bilz, M., Kell, S.P. & Nieto, A.
Contributor/s:	Osborne, J. & Kell, S.P.
Justification: European regional assessment: Data Deficient (DD) EU 27 regional assessment: Not Evaluated (NE) 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.

Geographic Range [top]

Range Description:	Endemic to Central and Eastern European Russia (Valdés and Scholz; with contributions from Raab-Straube and Parolly 2009).
Countries:	Native: Russian Federation (Central European Russia, East European Russia)

Population [top]

Population:	The population of this species is in severe decline. It has probably declined by 80% since 1950.
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	It is found in agricultural land where it is a specialized weed of a local landrace of Triticum dicoccon.
Systems:	Terrestrial

Major Threat(s):	It is threatened by the replacement of landraces with commercial crops.

Major Threat(s):

It is threatened by the replacement of landraces with commercial crops.

Conservation Actions [top]

Conservation Actions:	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.
