Tree Care

The Tree Care section was adapted from:

Tree Protection on Construction and Development Sites: A Best Practices Guidebook for the Northwest
Think Trees from the Ground Up
How to Recognize and Prevent Tree Hazards: Eight Warning Signs Every Homeowner Should Know
The Hazard Tree Prevention Webpage (offline), created by PNW-ISA and the Oregon Department of Forestry with a grant from OEM and FEMA. It was written by Greg Paulson and Paul D. Ries. Additional support was provided by the USDA Forest Service Urban and Community Forestry Program and the ISA.
