Expert Arborist Reports Across Hornsby Shire Council

Covering Hornsby, Waitara, Asquith, Berowra, Cherrybrook and every suburb across Hornsby Shire.

The Hornsby Shire combines established suburbs such as Hornsby, Waitara and Asquith with bushland communities including Berowra, Mount Colah and Cowan, as well as rural areas around Galston and Arcadia. Development near significant tree canopy often requires an Arborist Report before a Development Application or Tree Permit can proceed.

Which Arborist Report Do You Need?

Home extensions, dual occupancies and new dwellings are common throughout Cherrybrook, Hornsby, Galston and Berowra, where mature trees frequently require Arboricultural Impact Assessments and Tree Protection Plans.

Suburbs We Service Across Hornsby Shire

Hornsby Town Centre & Southern Corridor

  • Hornsby
  • Waitara
  • Asquith
  • Normanhurst
  • Wahroonga (Hornsby Council portion)

The commercial heart of Hornsby combines apartment redevelopment, established residential streets and mature urban tree canopy. Arborist Reports are commonly required for Development Applications, renovations and construction near retained trees.

Upper North Shore

  • Berowra
  • Berowra Heights
  • Mount Colah
  • Mount Kuring-gai
  • Cowan

These bushland-fringed suburbs adjoin national parks and contain significant native vegetation. Development often requires Arboricultural Impact Assessments, Tree Protection Plans and careful management of retained trees.

Rural & Semi-Rural Area

  • Arcadia
  • Galston
  • Glenorie (Hornsby Council portion)
  • Fiddletown
  • Berrilee
  • Forest Glen

Larger acreage properties and remnant native bushland mean Arborist Reports are frequently required for new dwellings, rural infrastructure, subdivisions and tree management.

Cherrybrook & West Pennant Hills

  • Cherrybrook
  • West Pennant Hills (Hornsby Council portion)

These established residential suburbs feature mature gardens, larger allotments and ongoing home renovations where Arborist Reports are commonly required for extensions, pools, knockdown rebuilds and tree removal applications.

Hornsby Shire Council Tree Rules

The State Environmental Planning Policy (Biodiversity and Conservation) 2021 provides the authority for tree preservation and removal across The Hills Shire, alongside Council's own Tree Preservation Order and Tree Management Guidelines for Private Trees.

  • General Rule
    Pruning or removal of trees on private property generally requires a permit, assessed by Council's qualified arborists using current industry methodologies.
  • Common Exemptions
    Removing a tree under 3 metres in height not located within native vegetation, removing deadwood, pruning up to 10% of canopy causing nuisance, and removing a tree within 3 metres of an approved dwelling (measured to the trunk at 1.4 metres above ground) are generally permitted without a permit.
  • Exemption Exclusions
    None of the standard exemptions apply within a Heritage Conservation Area, a Locally Significant Ecological Community, or an Endangered or Critically Endangered Ecological Community (including its 50-metre buffer).
  • When a Permit is Required
    This includes work beyond nuisance pruning, removal of more than 10% of a tree's canopy, trees in a Heritage Conservation Area, trees mapped as Biodiversity on the HLEP Terrestrial Biodiversity Map, and trees that are habitat for threatened species or ecological communities.
  • Accepted Reasons for Removal
    Likelihood of tree failure with no feasible remedial action, substantial and continuing structural damage to a dwelling, declining health with a life expectancy under 5 years, an unsuitable position threatening future major damage, or proven medical evidence linking a health condition to the tree. Structural and health-related reasons generally require a supporting AQF5 Arborist Report.
  • Development Applications
    Proposed development is considered under the development assessment process, not through a standalone Tree Removal Application. A Development Consent requiring trees to be retained or replanted will govern what can later be removed.
  • 10/50 Areas
    Eligible properties may remove trees within 10 metres and vegetation within 50 metres of the home under the RFS 10/50 Code, except where the property is heritage-listed or ecologically significant.
  • Replacement Planting
    Any approved tree removal must be replaced with a tree indigenous to Hornsby Shire, of like habit, planted as near as practicable to the original location, in accordance with Council's Green Offsets Code.
  • Need help?
    We can determine whether your project requires a Tree Application, Development Application or Arborist Report and prepare documentation to Council's Arborist Report Guidelines.

Understanding these requirements early can help avoid delays and ensure your project complies with Council's planning controls while protecting the Shire's bushland legacy.

Frequently Asked Questions

Is my tree exempt from Council approval?

A permit isn't required to remove a tree under 3 metres in height not located within native vegetation, deadwood, or a tree within Council's exempt species list. A tree within 3 metres of an approved dwelling (measured from the trunk to the external wall at 1.4 metres above ground) can also be removed by the owner without a permit.

None of these exemptions apply within a Heritage Conservation Area, a Locally Significant Ecological Community, or an Endangered or Critically Endangered Ecological Community. We can confirm exemption status before you proceed.

Do I need Council approval to remove a tree in Hornsby Shire?

In most cases, yes. A permit is required for tree work that isn't addressing nuisance, for pruning or removing more than 10% of a tree's canopy, for trees in a Heritage Conservation Area, or for trees mapped as Biodiversity or within a threatened or endangered ecological community.

What reasons does Council accept for tree removal?

Leaf, flower, fruit or sap drop, minor damage to paths or driveways, and a wish for more light or view are not accepted reasons where the tree is healthy.

Council does accept removal where there's a likelihood of tree failure, substantial and continuing structural damage to a dwelling, declining health with a life expectancy under 5 years, or proven medical evidence linking a health condition to the tree.

How soon can you attend for an urgent assessment?

Fast-track reporting is available for urgent and hazardous tree assessments, subject to availability.

Does a Development Application affect how tree removal is assessed?

Yes. Where tree removal is proposed as part of a development, it's considered through the development assessment process rather than a standalone Tree Removal Application. A Development Consent that requires trees to be retained or replanted will also affect what can later be removed without further approval.

Do you prepare reports for builders, architects and developers?

Yes. We prepare DA Arborist Reports at design stage, Tree Protection Plans post-approval, and Project Arborist inspections through construction for residential and commercial projects across Hornsby Shire.
