German forest is not close to nature and much too young

Study of the Natural Forest Academy: Almost 90 % of the forest area in Germany is in a poor condition in terms of nature conservation. This is the alarming conclusion of a recent study by the Naturwald Akademie. The authors of the „Alternative Forest Condition Report“ published that this lack of near-natural forest ecosystems is leading to a severe loss of biological diversity.

Without management: beech become larger and more stable

Study of the Natural Forest Academy et al: Depending on the degree of management, beech trees change their shape. If the forest is weakly managed or has not been managed for a long time, beech trees become more stable than in traditional forestry. In addition, the amount of usable wood increases significantly, which could have consequences for forestry in the future.

Mixed forests are more productive

Study shows that mixed forests are more productive. The study investigated the relationship between tree species diversity in forests and their growth performance. In 44 countries about 30 million trees were examined.

Forests protect plants and animals from climate warming

Study: The leaf canopy of the forests functions like an insulating layer. This protects the organisms living under it from the effects of global warming. On average, the maximum temperatures in the forest are 4°C lower than in the open. This shows how important the buffer effect of forests can be in climate change.

The special value of intact forest ecosystems

Study: Intact primal forests are the key to mitigating climate change, limiting biodiversity loss and achieving many of the UN’s sustainability goals. 21 representatives of scientific institutions from Australia, Canada, Sweden, the USA and the UN summarize the results of more than 200 studies in the fields of forest, ecology and climate research in this metastudy.

Biodiversity promotes forest growth

Study: A newly developed indicator can significantly improve forecasts of the consequences of climate change for our forests. Natural forest reserves serve as a reference for the adaptation of tree species and forest ecosystems to climate change. The accuracy of the indicator is likely to increase in the future.

Species-rich forests store twice as much carbon as monocultures

Study: Species-rich subtropical forests can absorb on average twice as much carbon as monocultures. With a mixture of native tree species, it is therefore possible to achieve higher productivity and thus better protect the climate.

Motivation for emergency logging is predominantly economic

Study: Extensive logging in protected forests is increasing. The so-called „sanitary cuts“ are generally intended to protect forest areas damaged by storms from attack by the bark beetle. However, this forestry instrument is used far too often. The protection of the forest or the safety of visitors is often only of secondary importance.

Trees also bind a lot of CO2 in old age

Study: Even old trees absorb a lot of carbon and thus remove CO2 from the atmosphere. Old trees thus also make an important contribution to climate protection. This has now been proven for the first time in a study conducted by the University of Hamburg.

Breeding birds prefer old structured forests

Study: Old and decaying trees are the best nursery for many forest birds. Old trees are therefore a particularly important part of their habitat.
