What do we mean when we talk about ‘valuing trees’?
Is it their monetary value? Tree Valuation systems such as the Helliwell System started by the Tree Council in the 1970’s and more recently the CAVAT system (Capital Asset Value for Trees) were developed to place monetary values on individual trees and tree groups. And trees have always had a financial value as a timber crop.
Or is it their value to society? Developed in the USA, ‘iTree’ gives statistical information about our treescape, quantifying its structure, and the environmental services that the trees provide. There are also a range of other online mapping systems that let us plot the trees in our neighbourhoods and determine their ‘ecosystem values’.
Or is it their value to the individual? These more intangible benefits of trees are much harder to quantify – like the value of the ‘oldest oak’, the ‘best tree to climb’ or ‘my favourite tree’.
Or is it their value to the environment? Such as the tree that ‘supports the rare Violet Click Beetle’ or provides a home for a dormouse.
In this forum, we will bring together all these elements and establish how understanding ‘Tree Values’ can help in our work as Tree Wardens.
