Crowdsourced mapping of garden lupines starts in Espoo on 26 May at 9:00. You can participate by installing the Crowdsorsa app on your smartphone.

The Crowdsorsa mobile game allows players to mark areas with garden lupines on the map. Players get a one-euro reward for each observation. Only larger areas within the city are included in the mapping process. You can find them on the Crowdsorsa application.

One week later, an invasive species control mission will also be added to the game platform, showing the lupines to be eradicated. The mission to eradicate the already mapped Himalayan balsam will be opened later in the summer. The game will determine the reward based on the size of the area eradicated.

The Crowdsorsa application(external link) is in English, but instructions are only available in Finnish.
