Tree Age Calculator:
Enter the values of tree’s girth, G(cm) and average annual growth rate, GR to determine the value of Tree Age, TA.
Tree Age:
Tree age refers to the number of years a tree has been alive since its germination or planting. Understanding the age of a tree is important for various ecological, forestry, and agricultural applications, such as determining growth rates, assessing health, and managing forest resources. Tree age can be estimated using growth rings, which are formed in the tree’s trunk and branches each year.
These rings are visible when the tree is cut or by using non-invasive methods like core sampling. Environmental factors, such as soil quality, climate, and water availability, can influence the rate of growth and, consequently, the number of rings.
The age of a tree can also be estimated based on its size, primarily using the tree’s girth or diameter at breast height (DBH). The relationship between the tree’s DBH and its age can be used in certain species of trees, though this method may require knowledge of the specific tree species’ growth patterns.
Trees grow at different rates depending on their species, location, and environmental conditions, so using local growth data and formulas specific to the species is recommended for more accurate estimates.
Tree Age, TA in years is equal to the tree’s girth, G(cm) in centimetres divided by the average annual growth rate, GR in centimetres per year.
Tree Age, TA = G(cm) / GR
TA = tree age in years.
G(cm) = tree’s girth in centimetres, cm.
GR = growth rate in centimetres per year.
Tree Age Calculation:
- Estimate the age of a tree with a girth of 120 cm and an average growth rate of 3 cm per year.
Given: G(cm) = 120cm, GR = 3cm/year.
Tree Age, TA = G(cm) / GR
TA = 120 / 3
TA = 40years.
- Given a tree’s age of 50years and an average growth rate (GR) of 4 cm per year, find the tree’s girth.
Given: G(cm) = 50years, GR = 4cm/year.
Tree Age, TA = G(cm) / GR
G(cm) = TA * GR
G(cm) = 50 * 4
G(cm) = 200cm.
