There is a large body of research showing the positive benefits of having trees in cities. Based on this research, a principle has been developed that serves as a working method with clear rules and objectives. This principle is called the 3-30-300 rule and is based on the following:
-
- All residents should be able to see 3 trees from their homes.
-
- That there should be 30% tree canopy coverage in each residential area.
-
- Everyone should be 300 meters from the nearest park or green space.
Working with 3-30-300 is an effective way to make cities more resilient and residents healthier, both physically and mentally.
During this course we will go through the different parameters (3-30-300) and link them to practical actions and strategic decisions. We will also address common questions such as:
-
- How do you measure 3-30-300?
-
- How can the 3-30-300 be used to communicate with, for example, politicians and the public?
-
- How can 3-30-300 be used in new construction and densification?
In addition, the course will focus on the different parameters in 3-30-300 and thus cover the following:
3
-
- How can parameter 3 be measured?
-
- How can trees be established in challenging locations?
-
- The Plantable Spots method, which is a method to increase the survival rate of trees at planting, is presented and discussed.
30
-
- There are currently a large number of ways to measure canopy cover, we will present the different methods and discuss the advantages and disadvantages of these methods.
-
- How can trees be preserved during e.g. construction to enable canopy cover to be maintained or increased?
-
- What is the scientific evidence for parameter 30?
300
-
- In Sweden, most people live close to green spaces, but how can the quality of an area be determined?
-
- Free or trap 3.0 applied to different environments
-
- We show how other managers have done to measure quality.
