The UTA presents 120 tree species and cultivars suitable for urban plantings. The trees were established in 2001 in replicates of three or six. Different pruning treatments allow for a comparison of their effect on the trees: formative pruning, shape pruning (topiary), pollarding and non-pruned. Tree dimensions are measured yearly and made available on the website www.bytraearboretet.dk. The website also offers photographic documentation of the trees and their tree features as well as a reference list open for entries by the public.
