Skellefteå municipality is now launching the app Crowdsorsa. Skellefteå residents will now be able to use the app to identify and then root out the invasive species Indian balsam.

– We want to make it easier, more fun and motivational for residents to help out in this important work. By using an app we can connect technology with environmental responsibility and commitment to the community, says Albin Cöster in a press release. He is a gardener and coordinator for combating invasive species at Skellefteå municipality.

When you have identified the plant you document the amount via a mobile video you upload in the app. After you have finished rooting out the plant you make a new video and the app will calculate how much money you have made from your work. According to a press release from Skellefteå municipality it should be possible to make up to SEK 200 per hour.

"You can use a scythe, secateurs or just pure muscle power to clear the weeds", says Toni Paju, MD of Crowdsorsa in the press message.

The municipality drew up an action plan in spring of 2024 for fighting invasive species such as Indian balsam. Now ahead of summer 2025 the municipality has earmarked SEK 36,000 to be able to pay those who contribute through the app.

The app went live on Monday. The project will be ongoing as long as the Indian balsam is in bloom or until the reward money runs out. 

Facts

An invasive species is a type of plant or animal that, due to human action, has been moved or spread to an environment where it does not belong. It often causes great damage to nature in the new environment.

Indian balsam is a plant that originally stems from the Himalayas. It multiplies very easily in the Swedish nature and forces away plants that are part of the Swedish ecosystem.
