Tree Pruning:

Certified Arborists with the Urban Tree Alliance demonstrate the techniques they use and what they look for when pruning large trees.

Tree Stabilization:

In this video we install a supportive cable high in the canopy of a Hackberry tree that has a weak branch union. The cable (actually a nylon rope) lessens the stress on the weak branch union and decreases the likelihood that the branch union would fail, causing part of the tree to fall into the street.  Preserving mature trees is very important to the Urban Tree Alliance, but we would never advise someone to leave a hazardous tree standing. Tree stabilization is one way of accomplishing both tree preservation and public safety!

Tree Removal:

The Urban Tree Alliance follows a strict tree removal policy that limits us to removals of dead/dying, hazardous, and invasive tree species. This video shows our arborists removing two hazardous trees at the University of Wisconsin Arboretum.
