|Taxonomic Notes:||The genus Sinapidendron is endemic to Madeira and is part of the brassica complex.|
|Red List Category & Criteria:||Endangered D ver 3.1|

Sinapidendron sempervivifolium is endemic to the island of Deserta Grande where its extent of occurrence (EOO) is no more than 10 km2, its area of occupancy (AOO) is no greater than 1 km2, and the population comprises less than 250 mature individuals. Although it has a restricted distribution and the population is quite small, the removal of rabbits and goats from the habitat of the species has allowed the population to recover. However, until the population shows a significant increase in the number of mature individuals, it is assessed as Endangered under criterion D. If grazing was reinstated in the habitat, it would also qualify for Vulnerable D2 due to the very restricted AOO. Long term monitoring of the population and habitat should be carried out to ensure that the species continues to thrive following the removal of grazing animals.
|Range Description:||This species is endemic to Deserta Grande in the Madeira archipelago (Buord and Lesouëf 2006) where its extent of occurrence (EOO) is no more than 10 km2 and its area of occupancy (AOO) is no greater than 1 km2.|

|Population:||The population comprises less than 250 mature individuals. Since the elimination of rabbits and goats from the habitat of this species, it has been able to recover (Buord and Lesouëf 2006).|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||It is a perennial, herbaceous to suffrutescent shrub that grows in rocky areas (Warwick et al. 2009).|
|Use and Trade:||It is a potential gene donor to cultivated Brassica species.|
|Major Threat(s):||It was threatened in the past by grazing of introduced species (rabbits and goats) (Buord and Lesouëf 2006). Landslides are a continuing local threat.|
S. sempervivifolium is listed in Annex I of the Convention on the Conservation of European Wildlife and Natural Habitats (Bern Convention). The species occurs within the Natura 2000 network.
No germplasm accessions of S. sempervivifolium are reported by EURISCO to be held in European genebanks (EURISCO Catalogue 2010). Germplasm collection and duplicated ex situ storage is a priority for this species.
|Errata reason:||An errata assessment has been produced to amend the growth form of the species (M. Rivers. pers. comm. 2017).|
