In connection with the construction of the Odense Light Rail, Building Biodiversity has provided independent consulting services focused on the city’s green infrastructure—with particular emphasis on follow-up quality assurance after the light rail system enters service. Our work has included surveying urban trees, assessing the condition of the vegetation, and providing advice and conducting a review of deficiencies regarding the management and protection of existing trees in the completed urban space. The goal has been to ensure that the green elements of the urban landscape meet the desired standards and contribute to a sustainable, well-functioning city. The Odense Light Rail is a key component of the municipality’s green transition—a 14.5-kilometer-long route that connects major hubs with CO₂-free electric power and strengthens alternatives to car traffic. Through our consulting services, we have helped ensure that natural and landscaping elements are actively incorporated into the city’s development—even after the project’s completion.
