Gieß den Kiez – or “Water your neighbourhood” is a platform for coordinating the watering of Berlin’s trees and encourages participation in protecting the city’s tree population. The map shows street and park trees with information on water needs, age, and species. Residents can check the water requirements in their neighbourhood, mark when and how much they have watered, and take on tree subscriptions. Currently, 967,365 trees are mapped (as of October 2025).
