Helsinki’s nature reserves

The City of Helsinki establishes several new nature reserves each year. As the primary purpose of these areas is to protect biodiversity, their use is restricted under protection orders. Many nature reserves also serve as popular recreational areas.

The City of Helsinki has established nature reserves based on the ecological value of birdlife and forests in particular. Almost half of Helsinki’s nature reserves are located on islands. The most important bird protection areas include Viikki-Vanhankaupunginlahti and the Östersundom bird wetlands. Haltialanmetsä is the largest forest nature reserve in Helsinki. There are also nature reserves on lands owned by the City of Helsinki in other municipalities: Sipoo, Espoo, Hanko and Ingå.

The Helsinki City Strategy 2025—2029 provides that the City of Helsinki will establish eight new nature reserves in Helsinki per year. The City of Helsinki Nature Conservation Programme 2025–2038 guides the city’s nature conservation efforts and the establishment of nature reserves. 

Implementing the programme will double the current land area of nature reserves in Helsinki from the current 5.2 per cent to 10.9 per cent. The area of protected sea areas will increase tenfold from the current 1 per cent to 11.7 per cent. 

The nature reserve programme is one of the tools for conserving and enhancing natural values in the City. In addition to preserving the diversity of species and habitats, nature reserves also help secure recreational and camping opportunities for local residents. 

You can find the sites included in the Nature Reserve Programme on the map at the bottom of the page. 

The City of Helsinki Nature Conservation Programme 2025–2038 (pdf, in Finnish)

Most of the City of Helsinki’s nature reserves are private nature reserves established at the initiative of the landowner (in most cases, the City of Helsinki). In the protection proposal submitted by the landowner, the landowner can propose restrictions on the use of the area. After a decision is made to place the site in question under a protection order, the private owner or municipality retains ownership of the area.

The process of establishing a nature reserve usually takes two to three years. The City of Helsinki primarily establishes new nature reserves in line with its current Nature Conservation Programme.

Phases of establishing a nature reserve

  1. The nature data on the planned nature reserve is complemented by nature studies carried out as needed. 
  2. The Environmental Services of the City of Helsinki prepare the protection proposal and a plan for the management and use of the nature reserve in cooperation with other experts and stakeholders. This process usually also includes an event for residents. Residents may submit written comments on the draft management plans. 
  3. The establishment proposal and management plan are then submitted to the City of Helsinki Urban Environment Committee’s Environment and Permits Sub-committee for consideration.
  4. Next, the Helsinki City Board considers the establishment proposal and management plan.  

  5. The Economic Development Centre in Uusimaa issues the protection decision for the nature reserve, and the Finnish Supervisory Agency approves the management and use plan.

  • Bredbacka (Mellunkylä)
