État de la populationTexte officiel évaluation IUCNExpert

Its total population size was estimated in 154,000 individuals in 2004 (Reyes-Betancort et al. 2004). A total of 2,788,741 individuals were recorded in 2007 (Gobierno de Canarias 2009). Population trend seems to be positive due to the decrease of agricultural and grazing pressures, but a potential re-activation of these activities would affect a very high number of individuals. The number of reproductive individuals fluctuates depending on precipitations.

Mesures de conservation recommandéesStratégies de conservation IUCNExpert

Androcymbium psammophilum is listed as priority species on Annex II of the Habitats Directive and under Appendix I of the Convention on the Conservation of European Wildlife and Natural Habitats (Bern Convention). It is included as species with “Protección Especial” in the national list of species in regime of special protection of Spain. It is listed as Vulnerable B2ac(ii) on the Spanish Red List (Moreno 2008).

In Lanzarote, populations are included in the protected areas Parque Natural Archipiélago Chinijo (SCI), Monumento Natural La Corona and Paisaje Protegido La Geria. In Fuerteventura it occurs within Parque Natural Dunas de Corralejo (SCI) and Monumento Natural del Malpaís de La Arena (SCI).

Proposed actions include the storage of plant material (seeds and bulbs) in germplasm banks and in living collection in botanic gardens, regulation of potential agricultural areas in Lanzarote, establishment of control measures on illegal quarrying and 4x4 vehicles access (Reyes-Betancort et al. 2004).
