This species is protected at the regional and European level. It is listed as a priority species in Annexes II and IV of the EU Habitats Directive and under Appendix I of the Convention on the Conservation of European Wildlife and Natural Habitats (Bern Convention). It is classed as Critically Endangered A1abc; B1ab(iii,v)+2ab(iii,v) in the Spanish national red list (Moreno 2008). The genus Diplotaxis is listed in Annex I of the International Treaty on Plant Genetic Resources for Food and Agriculture as part of the brassica complex.
The islet has been declared a Maritime-Terrestrial Reserve and Natural Place Paraje Natural by the Andalusian government, and has been nominated for the European Natura 2000 Network as SCI. Various reintroduction and re-enforcement campaigns were carried out in 1988 and 1999 to present.
Fortunately, before its extinction, some seeds had been collected and multiplied at the seed bank of the Agronomists College (Escuela de Agrónomos) of Madrid. When cultivated in botanic gardens (Jardín Botánico de Córdoba, Conservatoire Botanique de Brest), high germination rates can be achieved.
EURISCO reports only two germplasm accessions of D. siettiana held in European genebanks; however, only one originates from within Europe (Spain). This accession is stored in the genebank of the Escuela Técnica Superior de Ingenieros Agrónomos, Universidad Politécnica de Madrid (EURISCO Catalogue 2010). Germplasm collection and duplicated ex situ storage is a priority for this species.
This species should be added to the Spanish National Catalogue of Threatened Species, listed in the highest category (Endangered). Ideally the island should be designated as a strict Nature Reserve. If this is impossible, habitat restoration and on-going management still needs to be carried out indefinitely, including alien species eradication, monitoring, and no new construction of infrastructure. Periodic reinforcement campaigns in order to maintain the population might be necessary. The fact that D. siettiana seems to prefer semi-disturbed habitat and competes poorly with dominant species must always be taken into account.
