of the day: Tell your city leaders to build an urban tree adoption app!
Since 2020, the city of Berlin, Germany has been operating an app to help people volunteer to “adopt” urban trees.
The team at Technologiestiftung Berlin has made the code for their tree adoption app free and open-source. They also offer technical support for new cities seeking guidance on how to set up their own urban tree adoption apps.
U.S. city leaders should take this opportunity to set up a new, enriching, ready-to-go platform for residents to help sustain their urban trees! Tell your leaders to act now! Link below.
