European regional assessment: Least Concern (LC)
Armoracia rusticana is widely distributed and the population is stable to increasing. It often occurs as a ruderal plant in anthropogenic habitats and faces no major threats. It is therefore assessed as Least Concern.
A. rusticana occurs in Latvia; Lithuania; Estonia; Kaliningrad; east, north, northwest, south and central European Russia; Belarus; Moldova; and Ukraine (including Crimea) (Smekalova 2008).

|Population:||Common throughout its range with stable to increasing populations.|
|Habitat and Ecology:||It grows along riverbanks and in other damp places. Ruderal plants are mainly confined to secondary anthropogenic habitats; for example, near arable land, in urban areas and in rural gardens.|
|Use and Trade:||The species is a very popular spice known as horseradish and is widely cultivated. Wild populations are potential gene donors to the cultivated form.|
|Major Threat(s):||There are no major threats to this species.|
The genus Armoracia 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 102 germplasm accessions of A. rusticana held by European genebanks; however, only four of these are recorded as of wild or weedy origin. These wild accessions originate from Croatia (one), Denmark (two) and Ukraine (one) (EURISCO Catalogue 2010). Further germplasm collection and duplicated ex situ storage is needed to ensure that wild germplasm is available for use in plant breeding programmes.
