The City of Helsinki promotes biodiversity

The City of Helsinki approved its latest Biodiversity Action Plan (LUMO programme) in 2021. This action plan includes 95 measures. You can follow their progress on the LUMO-vahti website, which is a tool for monitoring the implementation of the action plan (currently only available in Finnish).

Nature conservation

Nature conservation efforts are based on the Finnish Nature Conservation Act, and their aim is to maintain biodiversity. The methods of conserving nature include placing nature reserves and natural monuments under a protection order and protecting natural habitats and species.

The Helsinki City Strategy 2021—2025 provides that the City of Helsinki will establish five new nature reserves in Helsinki per year. In 2022, the nature reserves in Helsinki covered approximately 1,400 hectares, of which one third consisted of water.

Helsinki has four Natura areas that are part of the European Union’s Natura 2000 network of protected areas. Additionally, Helsinki is home to protected natural habitats, defined in the Nature Conservation Act. They can be divided into three main groups: forest habitat types, shore habitat types and natural heritage types.

The City of Helsinki Nature Conservation Programme 2015–2024 (pdf, in Finnish) guides the city’s nature conservation efforts and the establishment of nature reserves.
