Longinoja is an urban brook that flows through Helsinki, the capital of Finland, into the Vantaanjoki River. Since 2001, voluntary stream restoration activities have been organized by SKES, the society for the promotion of Finnish fishing tourism industry. The restorations performed by volunteers have enabled the recovery of the endangered trout stock of the Gulf of Finland in the brook and the parr density is first-rate.

A social media community has been created around the brook, in which all members are interested in the condition of the brook and especially the trout swimming in it. This website acts as an open databank for the community.

We have managed to create something that is unique in Finland around the urban brook. Our goal is to provide information about a local natural site and to get people to enjoy a green gem of the urban concrete jungle”, brook activist Juha Salonen explains.

Unfortunately, we cannot translate this whole website into different languages, but our most important message is this: Enjoy the brook nature and remember to leave the trout in peace. We also want to kindly remind you that fishing is completely forbidden along the length of the Longinoja brook.

Together with other countries in the world, Finland is committed to halting the loss of natural diversity by 2020.  The Finnish Biodiversity Award was created to find innovative solutions that help reach the national and international goals.

The Biodiversity Award 2017-2018 goes to Mr Juha Salonen, the focal character in Longinoja Brook restoration, and the active brook restauration volunteers. Situated next to a major railroad, the urban Longinoja Brook was restored by a group of volunteers working together with many other actors, during a period of over 15 years.

“Thanks to active restoration work, the brook has now revived, and large numbers of threatened sea trout come again to spawn in the Longinoja Brook. This kind of hands-on work is important in the conservation of species. The volunteer work has opened the eyes of many city dwellers to the importance of urban nature areas,” says Minister of the Environment, Energy and Housing Kimmo Tiilikainen.

Visitors to Longinoja Brook can enjoy the diverse stream landscape because of the volunteer efforts. The restoration work has increased the knowledge of the participants on streams and the importance of the whole stream ecosystem. Longinoja’s nature trail with information boards was opened in late 2018, and thousands of people have already visited the stream nature trail. Information on Longinoja Brook is easily available on a website and in social media. Longinoja has also been able to get lots of media attention.

The Finnish Biodiversity Award was given out now for the seventh time. This time the competition attracted twenty-one high-level proposals. Two years ago, the award went to the Wolf Ambassadors of the Finnish Nature League – Luonto-Liitto for dispelling the fear of wolves among children and youngsters by disseminating science-based information.

International Union for Conservation of Nature (IUCN) is the oldest and largest environmental organisation and network in the world. The Finnish IUCN member organisations include the Finnish Government (represented by the Ministry of the Environment), the Finnish Association of Nature Conservation, WWF Finland, the Finnish Society for Nature and Environment (Natur och Miljö), BirdLife Finland, the Finnish Wildlife Agency and the Helsinki Zoo. Next to these members, the IUCN National Committee of Finland also includes the Ministry for Foreign Affairs, the Ministry of Agriculture and Forestry, the Finnish Environment Institute and Metsähallitus Parks & Wildlife Finland. A total of over 60 Finns volunteer in IUCN Commission work.
