Urban Green 2021+ - field trials research project
Due to climate change, traditional urban tree species suffer increasingly from drought stress and subsequently from pests and diseases. In search of stress tolerant and climate proof urban trees, LWG has been testing 30 promising species for the past ten years.
This long term project called „Stadtgrün 2021“ i.e. „Urban Green 2021“ involved the planting of 660 trees in total, spread across three different climate regions in Bavaria. Trees planted in 2009/2010 have been evaluated, resulting in regional lists of recommendations. For the trees on trial since 2015, first significant data is expected for 2021.
