City climate Hamburg
Asphalt deserts, busy roads, stunted trees – this is not the city of the future! The city of the future should be GREEN! A tour through Hamburg with Bernhard von Ehren!
Ash trees for the city
Which ash trees are suitable for the urban climate? We recommend three types that can stand up to the stress!
Climate-Adapted Urban Tree Plantings
This project investigates how the future urban tree population can be adapted to longer summer dry phases. To this end, suitable soil substrates are tested in combination with a selection of promising tree species and varieties.
Woody plants for wet feet
Which trees and shrubs are suitable for wet soils and for how long? The changes in precipitation, as a result of global warming, are leading to more frequent and heavier flooding. What to do?
