1. What is the Tree Age Equation?

The tree age equation estimates a tree's age based on its circumference and species-specific growth factor. This method is commonly used in the UK for quick age estimation of trees where direct age measurement isn't possible.

2. How Does the Calculator Work?

The calculator uses the tree age equation:

Where:

• \( Circumference \) — Tree circumference at breast height (cm)
• \( Growth\ Factor \) — Species-specific growth rate (cm per year)

Explanation: The equation assumes consistent annual growth, dividing the total circumference by the average annual growth to estimate age.

3. Importance of Tree Age Calculation

Details: Estimating tree age helps in forest management, conservation planning, and understanding ecological history. It's particularly useful for heritage trees and in urban forestry.

4. Using the Calculator

Tips: Measure circumference at 1.4m above ground (breast height). Use species-specific growth factors - common UK values: Oak (1.88), Beech (1.5), Ash (2.0), Sycamore (2.0).

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this method?
A: It provides a rough estimate. Accuracy depends on consistent growth conditions and proper growth factor selection.

Q2: Where should I measure circumference?
A: Measure at 1.4m (4.5 feet) above ground level, known as diameter at breast height (DBH).

Q3: Why do growth factors vary by species?
A: Different tree species grow at different rates under similar conditions due to genetic factors.

Q4: What affects a tree's growth rate?
A: Soil quality, water availability, sunlight, competition, climate, and disease all impact growth rates.

Q5: Are there more accurate methods?
A: Tree coring or counting rings provides exact age but is invasive. This method is non-destructive.
