Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2013
Date Assessed: 2010-12-30
Assessor(s): Santos Guerra, A. & Reyes Betancort, J.A.
Reviewer(s): Kell, S.P. & Nieto, A.
Contributor(s): Kell, S.P.
Justification:
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.

Geographic Range [top]

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.

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.

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).
