Trees that are in urban environments tend to suffer from being exposed to stressors such as pollution, inhibited growing areas, and damage. 0000140631 00000 n By weakening trees, air pollutants often predispose them to certain diseases (Kozlowski 1986).

A red maple's growth factor has been determined to be 4.5 and you have determined that its diameter is 10 inches: 10 inch diameter X 4.5 growth factor = 45 years. So, only use this data as a very rough estimate of a tree's age. gnc\px yH20800y I A red maplewith a 10-inch diameter and competing with other forest-grown trees can easily be 45 years old while a neighboring red oak with the same diameter would only be approximately 40 years old. There are foresters and arborists with enough tree core and stump evaluations under their belts who can age a tree with a degree of accuracy. It can be very difficult to calculate the age of a tree if you don't know when it was planted. The action you just performed triggered the security solution.

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. 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.

The interesting thing is that these sources are divided on whether an urban tree will 1) grow faster because its being pampered by being watered and looked after, or 2) will grow slower because its under duress from its life in a toxic city environment. Annapolis Junction, MD 20701 h1 04s\Gag&`'MF[!{ Because trees in a landscape or park are often pampered, protected, and sometimes older than forest-grown trees, it is more of an art to aging these trees without significant error.
