Berlin, August 1 – The health of Berlin’s street trees has shown a slight improvement, according to the latest report on the condition of street trees released by the Senate Department for the Environment. In 2025, 47 percent of the surveyed trees were classified as healthy, marking an increase from 44 percent in 2020.
Sycamore Trees Lead the Improvement in Health
Experts have been conducting comprehensive examinations of tree canopies every five years since 1978, utilizing aerial photographs for their assessments. The recent findings highlight a significant improvement in the condition of sycamore trees, with the proportion of healthy trees rising from 30 percent in 2020 to 40 percent in 2025. This represents the most substantial improvement among all tree types surveyed.
Maple trees also demonstrated a positive trend, with the percentage of undamaged trees reaching 33 percent in 2025, up from 29 percent in 2020. In contrast, the linden tree, which is the most common street tree in Berlin, maintained a similar health level to the previous survey, with 54 percent of trees reported to be in good health.
For this latest report, a total of 5,002 trees were assessed by experts, who rated their vitality on a five-point scale. The detailed analysis provides valuable insights into the overall ecological well-being of the city’s urban green spaces.
Methodology and Scope of the Survey
The Senate Department for the Environment employs a rigorous methodology for evaluating tree health. The use of aerial photographs, combined with expert analysis, allows for a comprehensive and consistent assessment of the urban tree population. This long-term monitoring, spanning over four decades, enables the city to track trends and implement targeted measures for tree care and preservation.
The five-point vitality scale used by experts considers various factors, including canopy density, leaf discoloration, and the presence of pests or diseases. This detailed evaluation helps to identify specific areas of concern and to prioritize interventions to maintain and improve the health of Berlin’s valuable street tree infrastructure.
Implications for Urban Planning and Environment
The improved health of Berlin’s street trees has significant implications for urban planning and environmental sustainability. Healthy trees contribute to better air quality, provide shade, reduce urban heat island effects, and enhance the aesthetic appeal of the city. They also play a crucial role in supporting biodiversity within the urban ecosystem.
The findings of this report will likely inform future urban forestry policies and management strategies. The focus on specific tree species, such as the sycamore, which has shown remarkable recovery, could lead to a greater emphasis on resilient and adaptable tree types in future planting initiatives. Conversely, understanding the consistent health of linden trees reaffirms their suitability for urban environments.
The Senate Department for the Environment continues to emphasize the importance of ongoing monitoring and proactive management to ensure the long-term health and vitality of Berlin’s urban forest. This commitment is essential for maintaining a green and livable city for its residents.
