Bryophyte and Lichen of the Year 2023

Urban heat island & climate change adaptation: mosses and lichens in green roofs: Tortella inclinata and Cladonia rangiformis are bryophyte and lichen of the year 2023 (text in German).

Cladonia rangiformis, Windsheimer Bucht, Franken [W. v. Brackel]After the temporal development of scientific findings was used as the selection criterion for Moss and Lichen of the Year last year, it is once again an ecological topic in 2023. This time, the focus is on the use of mosses and lichens in green roofs, which can be used to mitigate the overheating of cities in summer - keyword "urban heat island" - as well as the load on sewage systems during short heavy rain events. The one by cooling through water evaporation and the plant turf also acting as an additional thermal insulation, the other by absorbing and retaining rainwater and at best delaying runoff. These benefits of green roofs (but also green facades) are important for making our cities more resilient to the consequences of climate change. With Tortella inclinata and Cladonia rangiformis (photo), two species were selected that occur naturally in strongly drying biotopes such as semi-arid grasslands and also spontaneously colonize green roofs.
