|Scientific Name:||Crambe wildpretii Prina & Bramwell|
|Taxonomic Notes:||Crambe wildpretii Prina & Bramwell is a wild relative of the oil producing and fodder crop, C. abyssinica R. E. Fr., as well as being related to other brassica crops as a member of the subtribe Brassicinae (tribe Brassiceae) (Maxted et al. in prep.).
The species was recently described and it is possible that earlier records of C. gomerae relate to C. wildpretii.
|Red List Category & Criteria:||Critically Endangered C2a(i); D ver 3.1|
|Assessor(s):||Santos Guerra, A.|
|Reviewer(s):||Kell, S.P. & Nieto, A.|
Naranjo et al. (2008) recorded only 34 individuals of Crambe wildpretii, with 24 in one subpopulation and 10 in the other. There is a continuing decline in the number of mature individuals due to a decrease in the quality of the habitat caused by invasive species. It is also a very small and restricted population comprising less than 50 mature individuals. It is therefore assessed as Critically Endangered.
|Range Description:||C. wildpretii is endemic to La Gomera where it is found in the northwest of the island. Its area of occupancy (AOO) is less than 0.5 km2.|
Native:Spain (Canary Is.)
|Range Map:||Click here to open the map viewer and explore range.|
|Population:||There are two subpopulations comprising 34 individuals (24 in one and 10 in the other) which are found within two 1x1 km grid squares (Naranjo et al. 2008).|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||This perennial species grows on basaltic cliffs associated with the Erica and Myrica forest and dry scrubland.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Use and Trade:||It is a wild relative of and potential gene donor to the oil producing and fodder crop, C. abyssinica, as well as being related to other brassica crops. This species is also used as a vegetable (USDA, ARS, National Genetic Resources Program 2010).|
|Major Threat(s):||It is threatened by grazing, local landslides, invasive species, such as Agave spp. and Opuntia spp., and in the past it has been affected by reafforestation with Pinus radiata.|
The genus Crambe is listed in Annex I of the International Treaty on Plant Genetic Resources for Food and Agriculture as part of the brassica complex.
C. wildpretii occurs within the Monumento Natural Lomo del Carretón (Naranjo et al. 2008).
No germplasm accessions are reported by EURISCO to be held in European genebanks (EURISCO Catalogue 2010) and it is not known whether the species has been collected and conserved ex situ in the Canary Islands (A. Santo Guerra pers. comm. 2010). A review of its ex situ conservation status is required and germplasm collection and duplicated ex situ storage should be carried out as necessary.
