Status
Population sizes vary greatly from year to year; in Wiltshire and Dorset, some sites have in some years had hundreds of thousands of plants, and in other years, few or none. The seeds can remain viable in the soil for many years. In general, populations are in decline as the old chalk grassland is ploughed up, or fertilised, or remains ungrazed with the production of ranker vegetation, as it cannot compete with more vigorous species. The taxonomy of the plant is uncertain, with some people regarding it as part of a ''Gentianella amarella'' species group, so the International Union for Conservation of Nature
