Project Schlegel

Conversion from spruce monoculture to biodiverse mixed forest

471 ha in Thuringia
27,187 t CO₂

Project Description and Activities

The Schlegel project is converting 471 hectares of spruce monoculture in Thuringia into a future-proof mixed forest over a project period of 30 years.

Project activities such as the promotion of natural regeneration, the planting of new species and other activities listed on the right make the forest more resilient to the consequences of climate change such as storms, drought and beetle infestation.

Project activities

Promotion of natural rejuvenation
Introduction of new species such as chestnut
Improved wildlife management
Promoting individual tree species

Why we need forest adaptation

Beetle infestation

Prolonged drought weakens trees, which can then no longer adequately protect themselves against bark beetles and other infestations. As the trees are close together, a beetle infestation can easily spread to the entire forest and destroy large areas of it.


Forest areas with many tall and thin trees are more susceptible to storm damage (so-called windthrow). If, in addition, most of the trees in a section of forest are the same height, storms can lead to the loss of entire forest sections.
