État de la populationTexte officiel évaluation IUCNExpert

The species can occur in high population densities, for example, in semi-natural grasslands in Austria and Germany where, as it is toxic to livestock, control measures may even be attempted (Winter et al. 2013).

There have been some declines mainly as a result of agricultural intensification, for example in Ukraine. However, in its core distribution area, such as in parts of Germany and Austria, populations have increased recently.

Description complète des menacesTexte détaillé évaluation IUCNExpert

This is a widespread species and very common in the core of its range. However, it can be found in Red Data Books of several countries at the distribution limits: Great Britain, Ireland, The Netherlands, Luxembourg, Lithuania, Estonia, Belarus, Ukraine, Albania, Bulgaria and northern federal states of Germany. A decline in the number of sites has been noted in Poland and Ukraine mainly as a result of intensification of agriculture, draining, ploughing and re-seeding grassland. In addition collection from the wild is noted in Ukraine, Serbia and Poland (Jung et al. 2011).

The species is known to occur in semi-natural grasslands in Austria and Germany where, as it is toxic to livestock, control measures may even be attempted (Winter et al. 2013) which may pose a threat to local populations.

Mesures de conservation recommandéesStratégies de conservation IUCNExpert

This species occurs in national parks within its range, such as Tomorri National Park in Albania (Ruci et al. 2001). It is conserved ex situ in many botanic gardens and seed banks such as Royal Botanic Gardens, Kew, London, and the Botanic Garden and Botanical Museum of the Freie Universität Berlin, Germany (BCGI 2013, ENSCO 2014).

Agri-environment schemes that support low input agriculture may in this way promote population growth (Jung et al. 2011).
