The protection of the rare species <i>Crambe tataria</i> Sebeók (Brassicaceae) in the Bashkir Cis-Urals

Crambe tataria Sebeòk (Brassicaceae Burnett) is a rare species of flora of the Cis-Urals and the Southern Urals (the territory of the Republic of Bashkortostan). This species is in a near threatened state. The species is included in The Red Data Book of the Republic of Bashkortostan (2021). Crambe tataria is a valuable economically useful wild plant, belongs to the group of the Wild Relatives of Cultivated Plants. On the territory of the republic, this is a poorly studied species, located near the eastern border of the areal, known in the Bashkir Cis-Urals and the western foothills of the Southern Urals. The study and protection of this species is carried out in natural habitats ( in situ ) and when cultivated in nursery conditions ( ex situ ). The destruction of natural habitats is the main threat to the existence of this species. A method for creating artificial coenopopulations of this species ( ex situ ) is being developed.
