Crambe tаtaria Sebe´ok is one from four species of genus Crambe, which grow on the territory of Kazakhstan. This species is listed in Red Data Book of Kazakhstan as rare endangered species, and its natural habitats are chalk areas of west part of the country. The structure of seven populations of Crambe tаtaria was studied in the Aktobe Region. The optimum habitat conditions for this species are northern and northeast slopes of chalk uplands, chestnut and light-chestnut soils. In unfavorable conditions of summits and southern slopes of lime uplands, C. tаtaria can form invasive-regressive populations with the prevalence of virgin plants. The variation of the structure of the populations does not lead to a decrease in their resistance, which highlights high plasticity of the species within chalk uplands.
