Buried root systems can cause tree roots to encircle, girdle a tree stem, cutting off vital nutrients to the tree canopy and causing the tree to decline, die. Results of this study will help arborists and urban foresters better understand the association between the depth of soil over a tree’s first lateral root and frequency of these encircling, girdling root systems.enBuried Root SystemStem Girdling RootsStem Encircling RootsWorking Paper
