The artists created several sculptures from a total of 90 tons of sand and thus supported the charity project Pískoles – For a forest without bark beetles. Dita Korčák Hrtusová, the media representative of the organizer of the Happy Tree, zs and Pustevny sro project, told Deník that the project was created in the spirit of the fight against bark beetles and the rescue of Beskydy forests. The organizers want to educate visitors to Pusteven on this issue in an entertaining way. They will contribute with voluntary admission fees, which after the event are donated by the organizers to plant a new forest in the affected area. Lesy ČR is also cooperating on the project, and their workers will plant new trees.
