Demographic studies often point out the poor state of insular populations of Hacquetia epipactis. The species is under strict protection. This is due to both natural and anthropogenic factors, including the collection of intact plants for gardens. As a form of integrated protection, an attempt at ex situ propagation was undertaken using seeds and tissue culture.
Hacquetia epipactis (Scop.) DC. of the family Apiaceae is one of the most peculiar species in the Polish flora. Outside of Pogórze Cieszyńskie and Ślądk Opolski, it is found at a few isolated sites in southern Poland. It has been protected since 2004 as a rare species. It is listed as vulnerable in the Polish Red Book of Vascular Plants. This paper presents a comparison of two insular populations of H. epipactis in Pogórze Wielickie.
