|Scientific Name:||Avena canariensis Baum & al.|
|Taxonomic Notes:||Avena canariensis Baum & al. is a tertiary wild relative of oats, Avena sativa L. and A. byzantina K. Koch. (Maxted et al. in prep.).|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||Santos Guerra, A. & Reyes Betancort, J.A.|
|Reviewer(s):||Kell, S.P. & Nieto, A.|
Avena canariensis is assessed as Least Concern as it is fairly common and locally abundant on Lanzarote and Fuerteventura and the population is stable, despite being affected by grazing pressure at some localities. Its distribution requires clarification as Izquierdo et al. (2004) and the assessors believe it to be endemic to the Canary Islands, while Valdés and Scholz; with contributions from Raab-Straube and Parolly (2009) and USDA, ARS, National Genetic Resources Program (2010) record it as native to the Canary Islands and Morocco.
|Range Description:||According to Izquierdo et al. (2004), A. canariensis is endemic to the Canary Islands where it occurs on the islands of Tenerife, Fuerteventura and Lanzarote. However, Valdés and Scholz; with contributions from Raab-Straube and Parolly (2009) and USDA, ARS, National Genetic Resources Program (2010) record it as native to the Canary Islands and Morocco. According to J.A. Reyes Betancort and A. Santos Guerra (pers. comm. 2010) it occurs on Lanzarote and Fuerteventura and there is an old mention of it from Tenerife. However, they have not found it outside of the Canary Islands.|

|Population:||It is fairly common on Lanzarote and Fuerteventura where it is locally abundant and stable.|
|Current Population Trend:||Stable|
|Habitat and Ecology:||It grows in abandoned cultivated areas above 200–300 m and in stony places in grassland.|
|Use and Trade:||A. canariensis is a tertiary wild relative of and potential gene donor to oats, A. sativa and A. byzantina (Maxted et al. in prep.).|

The genus Avena is listed in Annex I of the International Treaty on Plant Genetic Resources for Food and Agriculture.
A. canariensis is listed as Vulnerable (VU) B2ac(iv) in the Lista Roja 2008 de la Flora Vascular Española (Moreno 2008).
Some subpopulations occur in protected areas, both on Fuerteventura and Lanzarote.
EURISCO reports 26 germplasm accessions of A. canariensis held in European genebanks, 19 of which are reported to be of wild or weedy origin; however, of the wild accessions, none are reported to originate from Europe (EURISCO Catalogue 2010).
