336 Bühler et al.: Growth of Street Trees in Copenhagen planted in planting stripes with large open surface area. Popu- lus had high growth rates even when planted rather exten- sively, i.e., without further soil amelioration, and can be used as fast-growing and inexpensive trees on difficult sites or to create temporary green structures when resources are limited and the risk of damage to urban infrastructure is low. Acknowledgments. This study was conducted on behalf of the City of Copenhagen, Vej & Park, financed in equal shares by the City of Copenhagen, Vej & Park, and the Danish Centre for Forest, Land- scape and Planning–KVL. We thank Jens Jacob Elkjær Knusen, Klaus Hansen Petersen, and colleagues from Vej & Park Copenha- gen for providing equipment and assistance and for their perpetual interest, inspiration, and help.
