European regional assessment: Data Deficient (DD)
Barbarea verna is assessed as Data Deficient as there is currently insufficient information available to evaluate this species. Information about its precise distribution, habitat preferences, population size and trend is needed, as well as its in situ conservation status and potential threats.
B. verna is native to parts of central, southwest and southeast Europe (Marhold 2011). This species has been widely introduced to the rest of Europe where it has become naturalized (Rich 1991). The species is widespread in France, occurring in the majority of departments across the country with the exception of Lot-et-Garonne, Lot and Haute-Garonne to the south and 16 departments in the north (Association Tela Botanica 2000–2010). Further research is needed to gather information about the precise distribution of this species throughout the rest of its range.
Native:Croatia; France (Corsica, France (mainland)); Italy (Italy (mainland), Sardegna); Portugal (Portugal (mainland)); Slovenia; Spain (Spain (mainland))

|Habitat and Ecology:||
Further research is needed to gather information about the habitat of this species in its native range.
|Use and Trade:||B. verna is a wild relative of and potential gene donor to cultivated B. verna (land cress) and winter cress, B. vulgaris. An example of a trait of possible use for future breeding programs is its pest resistance to pollen beetle (Warwick et al. 2009). Research has also shown that B. verna, with winter hardiness, relatively large seeds and high seed yields, has the potential to become a new oilseed crop (Andersson et al. 1999).|
Further research is needed to gather information about the potential threats to this species.
The genus Barbarea is listed in Annex I of the International Treaty on Plant Genetic Resources for Food and Agriculture as part of the brassica complex.
EURISCO reports seven germplasm accessions of B. verna held in European genebanks, four of which are reported to be of wild or weedy origin. Of the wild accessions, two originate from within Europe—one from Austria and the other from Spain (EURISCO Catalogue 2010). Further germplasm collection and duplicated ex situ storage is a priority for this species.
