A significant change compared to the previous forest management practices is that forests will be increasingly left to age naturally. The City is boosting forest biodiversity by means such as leaving decaying wood in forests. The aim is to create forests with trees of different ages and species [VH1] . Biodiverse forests are also better able to withstand the effects of climate change.
In its forest management, the City is preparing for an increase in the recreational use of forests and the densification of the city. The aim is to preserve local forests as sustainable and pleasant outdoor recreation areas. Most of the forest areas under management are located near residential areas and in key outdoor and recreational areas.
By managing its forests, the City is preparing for natural disasters and other risks posed to the sustainability of its forests. A warming climate increases the risk of things such as damage caused to old spruce forests by the European spruce bark beetle, which [VH2] is why the aim is to gradually introduce other tree species into spruce-dominated forests.
Come and learn about forest management by joining a nature walk
There will be a nature walk open to all on 16 September. On this walk, you will learn about Helsinki’s forest management measures through practical examples. We will set off [VH3] from the parking area of Neste Kannelmäki at 17.00. The work instructions will be available on the hel.fi website from 31 August to 27 September 2026, and you can submit feedback on them to the City of Helsinki Register Office during this period by emailing helsinki.kirjaamo@hel.fi(Link opens default mail program). The new work instructions are based on the forest management principles adopted by the City in 2024.
The City draws up nature and landscape management plans for different areas roughly every ten years, in collaboration with local residents. These plans define the management measures to be carried out in local and recreational forests, such as the thinning of the forest stand and small trees, as well as tree planting. The City’s foresters carry out the measures set out in the plans.
