Turoňová D., Hamerský R. & Ondráček Č.: The Eastern Pasqueflower – A Slightly Optimistic State of th

The Eastern Pasqueflower, in North America also known as the Prairie Crocus (Pulsatilla patens) is a plant species threatened at the pan-European level. At present, it occurs at approx. 20 sites in the Czech Republic.

In past, there were much more sites inhabited by the plant species and its numbers reached hundreds of thousands of individuals in some populations. During the second half of the 20thcentury, as a result of changes in land use and land management, the species drastically declined and this trend has not been fully reversed yet. Moreover, all the sites are annually monitored; at most of them, management coordinated by the Nature Conservation Agency of the Czech Republic is implemented. The management measures include mainly mowing and tree and shrub removal: some sites are also grazed. In addition, grass and mosses which have been left over from last season are removed by raking and experimental burning was also carried out. Seeds are collected and sown into the soil. Planting cultivated individuals is also supposed. Despite the intensive management, the species‘ conservation status is not optimal at some sites and the Eastern Pasqueflower has been declining in numbers there. Therefore, the wild plant species is a candidate for an Action Plan/Recovery Programme. These conservation instruments have had a long tradition in the Czech Republic, supporting the species by all necessary measures, namely by research, monitoring and management in the field. Last but not least, they help to solve administrative and financial issues (agreements with landowners, enacting statutory exceptions from basic protective measures, etc.).
