Arborists in Osborne Park: what's local
Two councils
Most of Osborne Park is in the City of Stirling, with part in the City of Vincent. Check the rates notice before you ring anyone about a tree.
Peat underfoot
Chinese and then Italian market gardeners farmed the swampy ground between Lake Monger and Herdsman Lake for its rich, peaty soil and fresh water. By the 1980s industry had taken over most of the suburb.
The lowest canopy on the list
Stirling measured Osborne Park's canopy at 3.5%, the lowest of the ten suburbs in its 2026 Themed Avenues planting. More than 200 street trees are planned for the industrial area over the 2026 and 2027 seasons.
Herdsman Lake
The City calls the lake the suburb's largest park, a regional recreation area and wildlife sanctuary. It's largely managed by the state's Department of Biodiversity, Conservation and Attractions.
Building near trees in Osborne Park
Stirling's Local Planning Policy 6.6 governs non-residential development. It wants one established tree kept for every 500m² of land, or a new tree planted where keeping one isn't practical, and new trees must be at least 2 years old with a 90-litre root ball.
On top of that, at least 10% of the site goes to deep-soil landscaping, and there's a tree for every 6 uncovered car bays. If the lot has no street tree, the City will plant one or more, with fees where that's a condition of approval.
The street trees stay City property and have to be protected while you build. Stirling says it's still losing large amounts of canopy every year, much of it through development on private land.
Questions to ask an arborist in Osborne Park
- Which of our trees could count toward LPP 6.6 if we redevelop, and which deserve an arborist report?
- How will you protect the street tree's roots and branches while trucks and machinery are on site?
- Will the pruning follow AS 4373-2007, and does the quote say so?
- Can you show public liability insurance and the qualifications of whoever goes up the tree?
- Where are the wood and chips going, given the shot-hole borer quarantine over Perth?
- Who manages pedestrians on the footpath while you work?
Tree pruning and lopping in Osborne Park
The City does, every year, to keep branches up off footpaths, out of drivers' sight lines and clear of infrastructure. Trees growing under power lines may also be pruned by Western Power for clearance. Don't have staff or a contractor cut them; only the City may prune a street tree.
Trees and power lines in Osborne Park
Don't try to clear it, and keep staff and customers away. Stay 8 metres back from any damaged line, report it to Western Power, and call 000 if anyone is hurt. WA's guidelines say pruning near lines takes trained people who know the voltages involved.
Hiring an arborist in Osborne Park
We'd confirm which council the lot is in first. For a commercial site, we'd have an arborist look at the trees before the design is fixed, so the keepers can be built around. For a house in the residential north-east, we'd check the title for a register notification and ask the City before a big tree comes down, with our WA permits page for the state rules.
