Pulling a tree out of the ground with roots attached
Uprooting is a form of treefall in which the root plate of a tree is torn from the soil, disrupting and mixing it and leaving a pit-mound.[1][2]
Purposes
Transplanting
Small trees can be replanted if their root system is well attached to the trunk.[3] Trees can suffer from transplant shock when moved to new environment, and that causes the tree not to be able to root itself properly.[3]
Ecosystem maintenance
Uprooting can be an effective method for efforts to remove unwanted woody species from an ecosystem, e.g., in the context of woody plant encroachment.[4]
