Both the cormorant and the barnacle goose are thriving species whose populations in Finland have increased considerably in recent years.

The most recent official barnacle goose data (autumn 2025 count of ~27,100 birds) shows a STABLE population, not a continued considerable increase in the most recent years.
The cormorant's population increase is best documented over the long term (since recolonisation in the 1990s); my searches returned the official monitoring project pages (Finnish Environment Institute, Luke) but no explicit 2025 nest-count figure in the search snippets.
Sources are an NGO monitoring page (BirdLife Finland) and official monitoring/project pages; no single primary statistical report with explicit 2025 figures for both species was retrieved.
