The publicly accessible Tree Register was established in July 2010. It contains such information as the distribution and conditions of and risk mitigation measures for important trees (Old and Valuable Trees (OVTs) and stonewall trees) and problematic trees that require close monitoring. The Tree Register is updated regularly. Departmental inspection officers assess the health and structural conditions of the trees on the Register and work out remedial actions and inspection timeframes (from several days to several months); while the TMO reviews the relevant risk assessment reports and conducts site inspections. Public can access the Tree Register website.
