|Scientific Name:||Crambe pritzelii Bolle|
|Taxonomic Notes:||Crambe pritzelii Bolle 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.).|
|Red List Category & Criteria:||Endangered B1ab(iii,v)+2ab(iii,v) ver 3.1|

Crambe pritzelii is assessed as Endangered. Its extent of occurrence (EOO) is less than 5,000 km2 and its area of occupancy (AOO) is less than 500 km2. The population is severely fragmented as it is found in isolated patches and the threats caused by invasive species and expanding human habitations is causing further isolation through habitat degradation and fragmentation. There is therefore a continuing decline in the area, extent and quality of habitat and in the number of mature individuals.
|Range Description:||C. pritzelii is endemic to Gran Canaria, where it is found in the lowlands of the north and east. Its extent of occurrence (EOO) is less than 5,000 km2 and its area of occupancy (AOO) is less than 500 km2.|
Native:Spain (Canary Is.)

|Population:||The population comprises small isolated groups of individual plants scattered throughout its range. The impact of invasive species and expansion of human habitations is causing increased fragmentation of the population.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||This perennial species is found in lowland scrub and in Juniperus, Olea and laurisilva forests. It also grows outside the forests in steep, rocky areas.|
|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.|
|Major Threat(s):||It is threatened by invasive plant species such as Agave spp., Opuntia spp., Pelargonium spp. and Pennisetum spp., as well as human disturbance due to the close proximity of subpopulations to human habitations.|
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. pritzelii is listed as Vulnerable (VU), C2a(i)) in the 2008 Red List of Vascular Plants of Spain (Moreno 2008).
Some subpopulations are found within protected areas, but these areas are affected by invasive species and there is no active management of the species.
EURISCO reports only one germplasm accession of C. pritzelii which 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.
