This method, which was first proposed by the International Society of Arboriculture (ISA), relies on a simple formula that uses the tree diameter at breast height (DBH), which is the tree's diameter at a point of 4.5 feet above the ground.

Explore the many benefits of ISA membership. Most foresters and tree experts say that there is a margin of error for estimating age based on whether the tree is in a natural or urban forest. For younger street and landscape trees, pick a genus or species from above and reduce the Growth Rate Factor by half. 0000133624 00000 n It's important to keep in mind that it is still impossible to do anything but estimate a tree age under these conditions.

By comparison, a Silver Maple with a diameter of 10 inches is 9 years old and at 30 inches is 65 years old: 3 times the size gives 7 times the age. These two methods give different results for the same tree. The ISA says that "tree growth rates are affected tremendously by conditions such as water availability, climate, soil conditions, root stress, competition for light, and overall plant vigor. Note: It is important to note that the data provided in the table is more precise for trees that are grown in a forest environment as these are typically thinner than those found in open conditions.
