When it comes to managing trees and forests, tree care professionals have access to a wide variety of guidelines and treatments. However, they don’t always have the big picture of how treatments interact with each other, how specific treatments relate to tree biology, and how effective tree management in rural areas differs from tree management in urban areas.
Northern Research Station scientists are addressing this need through extensive research and by creating practical, educational publications and presentations for urban tree care professionals. These cover a wide range of topics, including:
- how trees collect and store energy, water, carbon dioxide and other chemical elements,
- tree disease diagnosis and treatments,
- soil biology,
- recovering from crown injuries, and
- tree care methods such as pruning, fertilization and stabilization.
These results inform foresters and land managers that northern hardwood trees and forests can quickly recover from crown injury if they are in good condition at the time of the storm.
This research will improve the quality of tree care by providing a rational basis for choosing treatments for urban and community trees.
