    When immovable infrastructure meets irresistible trees: Using tree biology to make informed planting decisions.


    Trees are an integral part of the urban landscape from backyards to lining our streets. Media outlets cover disease and invasive pest issues in urban forests, but there is little mention regarding infrastructure and planting challenges facing urban foresters. Research has shown urban trees provide numerous benefits for society, many of which are not realized until trees have grown to a mature size. Trees are removed every year because of their conflict with urban infrastructure. Trunk flares may lift sidewalks and tree canopies often interfere with buildings or overhead utilities. This study’s intent was to create biological growth models for common Minnesota street tree species to provide urban foresters a practical method to predict urban tree form ultimately helping to better inform planting decisions to conflicts with urban infrastructure. 


    Eric North is currently a graduate student at the University of Minnesota studying urban tree growth and morphology. He has an interest in using science to improve natural resources in urban areas. Specifically, working with trees and their benefits in a built landscape. Education, outreach, and community engagement is critical to greening our urban infrastructure. Technology plays an important in the integration on natural resources with how people live and work. Eric works to combine his understanding of the natural world with his background in computer sciences to improve the interface between our build environments and our natural environments.
