About this app

Read full description

The TPZ app provides a tree protection zone radius calculator to assist those involved in the care and management of urban trees when or where construction and development activities are proposed. By inputting the stem diameter or stem circumference measurement, the calculation will then determine the TPZ radius - outlining the area required for protection of the root plate and tree crown.
