The Metsähallitus has found, among other things, ponds, as well as the rangi mussel and false blue mussel.
Several observations of new alien species have been made in the Archipelago Sea.
Metsähallitus marine team surveyors found a pond in the river mouth area of \u200b\u200bPaimionlahti. A perennial plant that grows in water spreads quickly.
In Mynälahti, on the other hand, there were several sightings of the false blue mussel. On the other hand, in the Selkä Sea, in front of the Eurajoki, observations were made of the barnacle mussel.
According to the Finnish Environment Agency (SYKE), non-native species are those that do better in warmer waters.
According to SYKE, species that benefit from the rise in temperature, such as the false blue mussel, are able to spread to new areas.
