Tree Management and Preservation

Council is committed to preserving the unique aspects of our Shire and has adopted tree preservation measures to protect our urban and bushland trees and vegetation. The tree preservation measures are administered through Hornsby Development Control Plan 2013.

These tree preservation measures are designed to protect the local amenity, landscape character and natural history of Hornsby Shire. The importance of trees is often taken for granted along with the benefits provided to the community such as social wellbeing, attracting people and visitors to the area, increasing property values, maintaining the environmental health of our region by protecting soil and water supplies, storing carbon and providing habitat for wildlife. Indigenous trees and many introduced species provide food, shelter and protection from predators for birds, animals and insects.

All trees in vegetation communities assessed as Regionally Significant, or of State or Commonwealth significance (Endangered or Critically Endangered Ecological Communities) are protected and will require consent for works that affect these communities. The exemptions to the tree and vegetation preservation
measures listed in the HDCP do not apply to trees and vegetation in these areas as indicated in the Terrestrial Biodiversity Map. These areas of high biodiversity value have legislated environmental protection placed upon them by the State and Federal Governments. The protection measures provide for:

  • Council administration of legislative obligations to ensure the protection of threatened species, populations and threatened ecological communities (CEECs and EEC’s) listed under the NSW Biodiversity Conservation Act 2016, NSW National Parks and Wildlife Act 1975 and  Commonwealth  Environment  Protection  and
    Biodiversity Conservation Act 1999.
  • All trees (including dead trees) regardless of size or proximity to an approved dwelling, that are characteristic of or form part of Regionally Significant or threatened Ecological  Communities are subject to protection.
  • The removal of trees and vegetation within an EEC or CEEC or threatened species may still require a licence or approval from the NSW Office of Environment and Heritage
