The Multidisciplinary afforestation project in Hasselager was created as a part of the local city development. The idea was to plant a forest close to a new residential area to build green and recreational sites for the citizens.
The new forest will have a multifunctional purpose of city-close nature area, with trees, meadows, paths, and lakes which gives the citizens access to green and recreational content. For example, some areas have been designed with tree trunks that can be used as recreational areas for play, and as a habitat for insects, birds, etc.

Citizens have participated in planning activities for the new forest and design with help of the municipality lead by the Nature and Water department in collaboration with the health department, citizens involvement department, children, and education department.
Trees that were planted received funding from the corporation Holmriis B8, which sells office furniture and was interested in donating trees for every piece of furniture they sell (5 trees per one piece of furniture).
