Summary of new Practice Note survey and replies from Lands Department

Lands Department (LandsD) has recently updated the Practice Note (PN) "Tree Preservation and Tree Removal Application for Building Development in Private Projects", Issue No. 7/2007 to a later version Practice Note "Tree Preservation and Removal Proposals for Building Development in Private Projects - Compliance of Tree Preservation Clause under Lease", Issue No. 2/2020 early this year. Since our arborists have been working closely with the LandsD on all sorts of tree issues, ISA(Hong Kong Chapter) conducted a survey to collect your opinions regarding the new PN in June 2020.
