DBH is a forestry term that means diameter (in inches) measured at breast height, which is 4.5 feet from the ground. Multi-stem trees are measured as one tree at the narrowest point above ground. Beyond size of the tree, removal pricing is based on the tree’s location within the property and the presence of obstructions such as overhead utilities, steep slopes or structures. The type of equipment that can access the tree can also influence the cost. Each company has a different business model with varying levels of staffing, education and overhead which can cause wide fluctuations in cost. Most companies carry at least $2 million aggregate in liability insurance because forestry and arboriculture work carries a high risk to the employee.
