New climate-resilient forest in Schleswig-Holstein
In spring 2025, a new and diverse mixed forest was established in Schleswig-Holstein on land that was previously used for agriculture. Together with the Schleswig-Holstein State Forests (AöR), we were able to finance the initial afforestation of approximately 6 hectares as part of a project covering a total of 8 hectares. The sites are located in the districts of Stormarn and Segeberg, in the municipalities of Mönkhagen and Strukdorf – in an area where new forests make an important contribution to climate resilience and to strengthening near-natural landscapes.
This new forest will develop into a climate-resilient, structurally rich ecosystem that sequesters carbon over the long term, promotes biodiversity, and creates valuable habitats for a wide range of plant and animal species.
The afforestation was carried out in spring 2025 following careful planning. The new woodland is characterized by English oak, which accounts for around 80 per cent of the trees, supplemented by European white elm, wild cherry, European beech, and red alder, as well as Norway and sycamore maple. Native shrubs were planted along the forest edges to create natural transitions and enhance ecological diversity.
The site, with its seasonally moist boulder clay soils, is intersected by small streams whose banks provide valuable habitats. The deliberate design of the forest edges creates structurally rich transition zones that enhance the ecological value of the area. The location of the afforestation is particularly important, as it connects two existing forest areas to form one larger woodland that also provides a refuge for sensitive species such as the white-tailed eagle, which breeds nearby.
The project – from site mapping and site preparation to planting and maintenance – was carried out by the Schleswig-Holstein State Forests in accordance with recognized forestry standards. Around 5 000 trees were planted across the 8-hectare site, and 41 250 of those were on the 6 hectares supported by our initiative. A fence was installed to protect the trees from wildlife, and inspections and clearing work are carried out regularly.
On the 8th of December 2025, the afforestation project was officially completed during an on-site visit. Carla, our Manager for nature-based climate solutions, visited the site alongside our partners on this project to see the newly planted forest for herself.
Our objectives for this site
- Improvement of climate, soil quality, and water balance
- Promotion of biodiversity
- Ecological and landscape enhancement of the region
- Measurable contribution to climate protection through long-term carbon sequestration of up to 10 tonnes of CO2 per hectare per year
