In June 2005 metaplantation of Eryngium maritimum and Epipactis atrorubens, from the build area of the Gdańsk Container Terminal into Sobieszewska Island was carried out. The reason for that immediate action was the unreliable report of the influence of investment on the environment, in which the mentioned above species have not been included. Metaplantation was conducted during one day time, by 21 volunteers. Altogether, 146 individuals of Sea Holly and 184 ones of Dark Red Helleborine have been translocated. Detailed measurements of each individual were made. On the new site, all planted individuals were permanently labelled. The newly constituted populations have been taken under monitoring. With regard to species of special concern, metaplantation of threatened populations seems to be the most beneficial form of nature compensation expected from the investors. Still, there are no unambiguous procedures for its executing.
