How long can trees survive without water?
A new podcast episode investigates the consequence of water deprivation to trees. Peter Wohlleben, a NY-times bestselling author and forester, interviews Dr. Karin Pritsch, from the Helmholtz Institutes, and Prof. Thorsten Grams, from the Technical University of Munich. The two scientists recount the five-year experiment they perform to study the ability of trees to cope with these extreme drought conditions.
The experts talk in detail about what happens below the ground when no water is given to the soil for five years: in particular, they focus on the quantitative decline of roots and mycorrhizae. Listen to the full episode (in German)
