Research clearly shows that urban trees contribute to improved public health, climate resilience and quality of life. To put this knowledge into practice, Professor Cecil Konijnendijk has developed the 3+30+300 rule, a methodology with clear targets:

• Three trees should be visible from every window in the residence
• 30% tree canopy cover in each residential area
• 300 m to the nearest park or green space

Working with 3+30+300 is a powerful way to strengthen the link between the city's green infrastructure and people's well-being, physically, mentally and socially.

During the training, we’ll cover all aspects of the 3+30+300 principle and link them topractical measures,strategic decisions, andcommunication tools. The course is designed for those who work in urban planning, green space management, community development, or sustainability issues.

We discuss the following issues, among others:

• How is 3+30+300 measured in practice?
• How can the model be used in communication with politicians and citizens?
• How are the principles integrated into the planning of new buildings and densification?

3 trees in the spotlight

• How to measure visual contact with trees?

• Overview ofthe Plantable Spots Method– for Improved Survival Rates in New Plantings.

30 % Tree canopy cover

• Overview of different measurement methods - strengths and limitations

• Scientific support for the 30% canopy cover target

300 m to the nearest green areas

• How can we assess the quality of the green space, not just its distance?
• Examples of how different municipalities and managers measure and ensure quality
• Application of the "Fria eller fälla 3.0" Tool in Various Environments
