You need a tree-felling permit in order to:

• Cut down a tree whose trunk is 10 cm in diameter or more, measured 1.4 m from the ground, or 15 cm in diameter or more, measured 15 cm from the ground.
• Raise the ground level more than 20 cm beneath the branches of a tree.
• Cut 50 per cent or more of a tree’s branches.
• Cut 40 per cent or more of a tree’s roots.
• Do anything else that might affect a tree’s survival, such as putting a ring around the trunk, covering the base with impermeable material, etc.

Diameter of the trunk

To calculate the diameter of the trunk before applying for a permit:

1. Use a tape measure.
2. Measure around the trunk in cm.
3. Divide your measurement by 3.14 to obtain the diameter in cm.

Example: If the trunk measures 35 cm, the diameter is 35/3.14 = 11 cm

Another way to obtain the diameter is to use a rigid tape measure and hold it horizontally against the tree to measure the width (or thickness) of the trunk. You will get an approximate diameter.
