NATIONAL TREE MAP™

Trees play a vital role in day to day life - improving the air we breathe, providing valuable habitats for our wildlife, and conserving energy by naturally cooling nearby buildings. However, they also pose a risk to properties, networks and subterranean assets, by causing subsidence or pipeline fractures through root damage, and endangering overhead lines through trees falling and loose branches. It is therefore essential that those involved in tree and vegetation management have access to the most accurate and comprehensive data available.
