The public works department of the municipality of Leeuwarden faces a major green challenge this winter. By May 2026, more than 1300 trees will be planted in the municipality. Some replace sick, dangerous or dead trees, but the majority, more than 760 trees, are completely new.

This planting is a major step taken within the framework of the Greening implementation program, in which the municipality will add nearly 7000 new trees to neighborhoods and villages over the next ten years. These additional trees are needed due to longer periods of extreme heat or heavy rainfall.

Alderman Evert Stellingwerf emphasizes the importance of this investment in greenery: “Nature nearby is not only beautiful. The trees we plant help solve problems in urban areas. Trees absorb excess rainwater, reducing the burden on the sewer system. They also provide shade in summer. In areas with a lot of pavement, we consciously choose tree species that offer optimal cooling. With enough space for greenery, every tree can grow old healthily and contribute maximally to a healthy living environment for people and animals.”

Trees in villages and neighborhoods

Some locations were suggested by residents through village interests and neighborhood panels. The municipality focuses on locations spread throughout the municipality. On the website GroenleeftinLeeuwarden there is a map with the locations of the new trees and information about what else the municipality does in the field of tree management.

In many places, the new trees are already visible, or there are three tree stakes ready where a tree will soon be planted. The municipality tries to plant all trees before May 1. This depends on weather conditions. Work is temporarily stopped in case of frost or too wet soil.

Tree management in numbers

The municipality currently manages 61,000 trees and 325 hectares of forest. In total, about 176,000 trees grow throughout the municipality, together covering 1270 hectares of canopy.

Cool and healthy living environment

Annually, the trees sequester nearly 8,000 tons of CO₂, filter about 62,000 kilos of air pollution, and drain over 240,000 m³ of rainwater. They thus form a powerful, living network that makes the city and villages cleaner, cooler, and healthier.
