The cyanobacterial situation in lakes has deteriorated in some places since last week, although the national situation in lakes remains calm. In sea areas, the number of surface blooms has decreased, and the cyanobacteria have mixed with water in many places. The warm and calm weather may further increase the number of cyanobacterial blooms in late summer. In some places, dead cyanobacterial cells have washed up on the beaches, dyeing the beaches turquoise because of the colour pigment in the al

According to a new study, the growing White-tailed Eagle population affects both the location of the Great Cormorant’s nesting colonies and their breeding performance. The White-tailed Eagle plays an increasingly important role in limiting the Great Cormorant population. Finland’s Great Cormorant population has not grown since 2015.

The cyanobacterial situation has improved slightly since last week. The number of cyanobacterial observations in lakes has diminished as a result of the windy and rainy weather, and the poor cyanobacterial situation in sea areas has also improved somewhat.

There are now cyanobacterial occurrences in all sea areas. Abundant cyanobacteria have been observed especially in the coastal areas of the Archipelago Sea and the Gulf of Finland. The situation in lakes is still better than usual, but observations have been made at more observation sites than last week.

There has been a sharp increase in cyanobacterial observations both on the coast and in the open sea. Observations have increased in both the Gulf of Finland and the Gulf of Bothnia. The cyanobacterial situation in lakes has remained above average levels, although observations have increased slightly due to the warmer weather.
