Forests store CO₂ and are therefore indispensable for climate protection. An important role is played by the forest floor, which suffers massively from extensive wood use and monocultures. But how can sustainable, climate-resistant management be achieved?
Henrik Hartmann and other forest researchers talk about the silvicultural use of forests in Deutschlandfunk Kultur's Zeitfragen feature.

Bleak times for the forest: drought years, storms and pest infestations are taking their toll on Germany's forests. Tagesgespräch asked: What are you observing? What damage is evident in nature? What can help the forest in the long term? Moderator: Henrik Hartmann is Eva Kötting's guest on BR 2 Tagesgespräch.

Climate change is putting stress on the forest. Yet forests are precisely what is supposed to help reduce global warming. A scientist says: Because the conditions for the forest are so bad, this will be difficult.

Drought, bark beetles and heat: our forests are not doing well. Large groups of brown-dried spruce trees and bare slopes are unmistakable. Are you worried about the forest, too?

The new report of the IPCC addresses the question of how we can adapt to the consequences of climate change. This question also applies to the forests in our backyard. Forest scientist Henrik Hartmann argues that scientific facts, rather than a fictional forest idyll, should form the basis of a sustainable strategy.

Germany invented “scientific” forestry. But a huge dieback triggered by climate change has ignited a fierce debate over how the nation should manage its trees.

The effects on wildlife and the ability of forests to store CO₂ from fossil fuels could be enormous.

Germany is to reforest 84 square kilometers of forest under the EU's Green Deal. Tree-planting campaigns for climate protection are en vogue at the moment - but often surprisingly little remains of them afterwards.

What strategies do trees use to survive climate extremes? Experiments from Jena show: Pines stop growing and digest themselves, but retain some sugar reserves.

The climate is changing faster than our trees can adapt. Experts now want to plant more cedars from Turkey and Douglas firs from North America. What's the point?

Forests in Germany and other parts of Europe are being hit very hard by climate change. Previously unquestioned beliefs about which trees can withstand heat and drought no longer apply. That's why ecophysiologist Henrik Hartmann is advocating the creation of an interdisciplinary Institute for Forest Restructuring. It should provide scientific insights into how forests can be designed to withstand ongoing global warming.

Forests are huge CO₂ reservoirs and are considered a miracle cure for pushing global warming below two degrees after all. But ecologists increasingly doubt that the plan will work.

The forest is suffering. Yet time and again, investors are promised to help nature through targeted investments. Yet many financial products are quite risky.

Bark beetles, drought, climate change: German forests are in a dramatic situation. There is money for forest restructuring. But which trees will still be able to survive in 50 years?

The showers and rainfall at the beginning of May can hardly alleviate the extreme drought in March and April. Especially in the forests, the trees lack water. And summer is yet to come.

The forest in Germany is suffering. Dead trees and thinning crowns already in summer clearly show how it is doing. Henrik Hartmann, head of a research group at the Max Planck Institute for Biogeochemistry in Jena, is looking into the question of how the forest must change if it is to survive as climate change progresses. We spoke with him about the state and future of the forest, and how science and policy can support forest transformation.
