Activities for environment

Is your neighbourhood untidy? Would you like to do something for the parks and nature? City residents can participate in various volunteer activities in the public green areas, including cleaning, planting, weeding and renovation. You can help take care of the neighbourhood and make it more comfortable.


Clean-up events

Voluntary clean-up events have been organised in Helsinki since 1984. All Helsinki residents can organise voluntary clean-up events in public areas of their choosing. The areas to be cleaned can consist of the city’s public green spaces, such as forests, beaches, roadsides and parks. The organiser notifies the location and time of the event and will be provided with litter pickers and refuse sacks. Other tools can also be borrowed. The equipment will be provided by the regional green area contractor. The organiser will receive the contact details of the regional contact person upon notification to agree on the details of the work, if necessary. The notification must be given no later than two weeks before the activity. Voluntary clean-up events can be organised during snow-free times.

The events are communicated online at Volunteer activities can also be notified by calling the Urban Environment Division’s customer service, tel. +358 9 310 22111.

Volunteer activities against invasive species

Invasive species are, for example, plants and animals that have spread to our environment through human intervention, either intentional or unintentional. They are classified as harmful if they have a negative impact on our nature or indigenous species, for example, through competitive exclusion or hybridisation. There are several invasive species in Helsinki’s green areas, threatening the diversity of our urban nature. Many areas are difficult to reach with machines for mechanical removal. Therefore, all hands are needed to combat invasive species.

If you want to participate in this conservation work, please take part in the city-organised activities against invasive species, or organise a volunteer activity yourself. The activities mainly focus on combating invasive plant species. Volunteer activities must target city-managed areas, i.e. public areasWhen invasive species are eradicated in cooperation with the city, the city will arrange for the removal of the resulting waste and provide guidance and help in organising the activity.

City-organised activities can also be found on the Helsinki Park Pals’ Facebook page (in Finnish).


Flower bulb planting campaign

In the autumn, the Urban Environment Division hands out flower bulbs to residents for planting in public green areas. The place of planting must always be agreed on with the city, and you can also ask for expert help in choosing the place.

The number of bulbs provided can vary between 100 and 3,000. The more bulbs you plant, the more spectacular the result. However, the bulbs must also have sufficient space to grow. Therefore, the choice of location greatly impacts the type and number of bulbs to be planted. There are separate instructions for choosing the location and actual planting at the end of this article.

The bulbs are handed out in September-October, and they should be planted before the ground freezes, preferably during October. If you are interested in organising a volunteer planting event or just want to plant bulbs to embellish your neighbourhood, please contact Please note that the number of bulbs is limited. Those who miss out on this time will be prioritised on the next year’s list.

Normally, the event takes place in early June. The time of the next planting event will be announced closer to the date. If you want to participate in the planting event to make Karhupuisto a summer flower paradise, please contact The city will borrow the planting tools. Gloves are also available, but bring your own gloves if you have them.
