Some of the protected yellow iris (Iris pseudacorus, IUCN classification: Least Concerned LC) population was located in the construction area. The plants were transferred to another suitable habitat at the Hanhikivi headland in the end of April 2016. For the transfers, an exemption permit has been granted to Fennovoima. Monitoring of all transferred yellow irises was conducted in June 2016. The plants were well rooted to their new location.
A breeding area for moor frogs (Rana arvalis, IUCN classification Least Concerned LC) was located near the future harbor area. An exemption permit has been granted to Fennovoima which enables it to destroy this breeding area. The exemption permit included an obligation to transfer the moor frogs to another suitable habitat at the Hanhikivi headland.
At the end of April and the beginning of May 2016, during the breeding season of the moor frogs, Fennovoima attempted to transfer the moor frogs, but no moor frogs were found. According to the authority, Fennovoima’s efforts to find the moor frogs were sufficient, and Fennovoima was able to proceed with the construction work at the harbor area.
The most significant impact on the bedrock is that the excavation takes place in the Hanhikivi conglomerate area that differs geologically from the rest of the region, which decreases the geological value of the area. Representative parts of the bedrock will be left exposed.
