Struggling Forests in Saxony-Anhalt: A Challenging Year of Heat and Drought
Forests in Saxony-Anhalt, Germany, are grappling with adversity as the impact of extreme weather conditions persists. CDU's Forestry Minister, Sven Schulze, voiced his concerns during this year's Forest Condition Report presentation, admitting that the forests remain in an "extremely poor" state.
The forest's battle against the elements has seen a significant increase in tree damage over recent years. Spruce, the most prevalent tree species, has suffered the most, with over two-thirds showing severe signs of crown thinning. Ulrike Talkner, Head of the Environmental Control Department at the Northwest German Forest Research Institute (NW-FVA), revealed that only a meager 2% of Saxony-Anhalt's spruce trees have a complete crown.
Climate change plays a significant role in this deteriorating state of the forests. The unprecedented heat of 10.8°C in 2023, ranking as one of the warmest years since 1881, and the irregular distribution of precipitation have taken a toll on the region's flora.
Tackling climate change and aiding the forests' recovery, the Saxony-Anhalt government has pledged to invest approximately 11.8 million euros in reforestation initiatives. Forestry Minister Schulze acknowledged that this substantial investment marks the beginning of a multi-decade project.
Recognizing the importance of private property and forestry, the Saxony-Anhalt government is actively engaging with more than 50,000 private forest owners. Supporting landowners in maintaining and restoring forest ecosystems is essential to combat the ongoing dryness affecting the region.
Climate Change's Effects and Mitigation Strategies
Extreme weather conditions and drought have given rise to challenges in Saxony-Anhalt's forests. These consequences include tree dieback due to bark beetle infestations, increased nitrogen levels in streams, and disruption to forest ecosystems.
Various strategies aim to improve forest health and mitigate climate change's effects. These include reforestation initiatives, ecological restoration projects, nature conservation efforts, grazing projects, and scientific research.
One innovative approach involves integrating foreign tree species, such as the black locust, recognized for its resistance to drought and its contribution to improved soil quality. The Oranienbaum Heath grazing project and Middle Elbe - Black Elster project emerge as key efforts to restore biodiversity and balance forest ecosystems.
Scientific research and monitoring, like hydrochemical and hydrobiological studies in selected streams administered by the University of Applied Sciences Magdeburg-Stendal, provide valuable insights into the health of the forest and its requirements.
In conclusion, the continuous struggle against climate change in Saxony-Anhalt brings immense pressure on its forests, but ongoing efforts to restore forest health through reforestation, ecological restoration, and conservation projects, in tandem with scientific research, offer hope for the future of these vital ecosystems.

In a warming climate, Saxony-Anhalt’s forests face several challenges:
- Higher temperatures lead to increased mineralization and DOC release from forest soils, affecting water quality and potentially harming aquatic ecosystems.
- Climate change amplifies acidification in streams and rivers, harming aquatic life and querying the overall health of the ecosystem.
- Frequent and severe droughts and extreme weather events, brought on by climate change, stress forest ecosystems and expose them to disease and pests.
To address these challenges and help forests recover, several mitigation strategies have been employed:
- Recovery of streams in the Harz National Park focuses on addressing acidification. This includes reducing DOC release from forest soils and improving water quality.
- Nature conservation projects across Saxony-Anhalt are preserving and improving floodplain habitats. The "Middle Elbe - Black Elster" project involves stabilizing the water balance of floodplains, reconnecting old watercourses, and creating new small bodies of water to enhance habitat quality.
- Sustainable forest management is a crucial practice, which includes selective logging to reduce climate change's impact on forests and reforestation efforts that promote biodiversity and resilience.
- Ecological restoration projects, such as those in the Elbe river landscape, aim to restore natural processes and improve ecosystem services. This includes desilting old watercourses and creating new small bodies of water to support floodplain habitats.
These strategies aim to bolster the resilience of forest ecosystems in Saxony-Anhalt, enabling them to better withstand the impacts of climate change.
