In October 2019, on National Tree Day, three tree planting events were held in Silesia – in Katowice, Bielsko Biała, and in Ustroń. 186 participants planted a total of 225 trees, shrubs and perennials. Educators from Klub Gaja conducted workshops on climate protection and biodiversity for local residents and students. Workshop participants built 31 houses for wild pollinators, which were placed in urban green spaces, in wooded areas and in school gardens.
