In the past, the Marsh angelica (Angelica palustris) had occurred in what is now the Czech Republic at seven sites. Moreover, from most of them, the vascular plant species disappeared by the 1950s.
The site near the village of Hrdibořice (District of Prostějov, Central Moravia) was the last one. In 2000, the Marsh Angelica Action Plan aiming at species´ survival was approved by the Ministry of the Environment of the Czech Republic. Consequently, in 2013 assessment of the Action Plan, one of the oldest in the Czech Republic, was finalised. Its main goal has been to recover viable Marsh angelica populations at minimally two sites. As the most suitable sites with good prospects for species´ reintroduction, the sites near Hrdibořice and Černovírské slatiniště/Černovíry Fen near the city of Olomouc (Central Moravia) were selected. At both sites, necessary filed measures have been implemented, e.g. regular mowing and since 1988, the critically endangered wild plant species has been re-introduced there. At the Hrdibořice site, the Marsh angelica population has been fully recovered. For fulfilling the Action Plan main goal, the species´ population should be successfully recovered at minimally one more site. Because the goal could be reached in a relatively short-term period, a proposal to update and to renew the Action Plan for the next five years was approved by the Ministry of the Environment of the Czech Republic.
