Capital Asset Value for Amenity Trees (CAVAT)
Capital Asset Value for Amenity Trees (CAVAT) is a tool, developed by Chris Neilan, which can be used to express the public amenity value of urban trees in monetary terms. It can be used as a strategic tool to help decision-makers manage the urban tree stock as a whole, or it can be applied to individual cases when a single tree needs to be valued, e.g. for calculating compensation when a tree is damaged.
The CAVAT tool can therefore be used in two ways. The ‘full method’ is recommended for use in decisions concerning individual trees or groups, when precision is required and sufficient time is available for a full assessment. The ‘quick method’ is intended specifically as a strategic tool for management of the stock as a whole, as if it were a financial asset of the community.
