1. What is a Tree Value Calculator UK?

Definition: This calculator estimates the monetary value of a tree based on its size factor, regional rate, and environmental contribution.

Purpose: It helps arborists, property owners, and local authorities determine the economic value of trees for insurance, planning, or conservation purposes.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Tree value (GBP)
• \( S \) — Size factor (dimensionless)
• \( R \) — Regional rate (GBP)
• \( E \) — Environmental value (GBP)

Explanation: The size factor multiplied by the regional rate gives the base value, then environmental benefits are added.

3. Importance of Tree Valuation

Details: Proper tree valuation helps in compensation claims, planning decisions, and recognizing the true worth of urban trees beyond just aesthetic value.

4. Using the Calculator

Tips: Enter the size factor (typically based on trunk diameter or canopy size), regional rate (varies by location), and environmental value (based on carbon sequestration, biodiversity, etc.).

5. Frequently Asked Questions (FAQ)

Q1: How is the size factor determined?
A: Size factor is typically calculated from trunk diameter (DBH in cm) divided by a standard factor, or from canopy volume measurements.

Q2: Where can I find regional rates?
A: Local councils or arborist associations often publish regional rate guidelines for tree valuation.

Q3: What contributes to environmental value?
A: Factors like carbon storage, air purification, stormwater management, and biodiversity support contribute to environmental value.

Q4: Does this calculator follow CAVAT methodology?
A: This is a simplified version. For official CAVAT assessments, consult a qualified arborist.

Q5: Can I use this for insurance claims?
A: While it provides estimates, formal claims may require professional assessments.
