The three German cities Frankfurt, Dessau-Roßlau, and Hannover have set aside certain urban lots for urban wilderness projects scheduled to run for a period from 2016 to 2021. The intention and goals are in:

•  supporting conservation by providing spaces for species and biodiversity development, 
• improving life quality in the cities, fostering curiosity and interest in "wildlife", and making natural environments accessible,
• creating new urban landscapes and making experience with maintenance and usage,
• pioneering various options and schemes for urban wilderness projects.

The allotted spaces remain largely uncultivated and are allowed to partly regulate themselves. Of course, we remain the guardians!
