Mature tree specialists
Davidson's trees deserve an arborist who knows what they're doing
Davidson is one of the Northern Beaches' most consistently leafy residential areas. The suburb runs along Warringah Road, Kelvin Road, De Burgh Road and Penrose Road, backing onto the western edge of Garigal National Park. Blocks here tend to be generous, with good setbacks, and the original vegetation has largely been retained or supplemented over decades of residential occupation. The result is one of the most mature and continuous suburban tree canopies in the area.
The trees in Davidson are mostly in the 40–60 year age bracket — the age at which many species move into the phase of life characterised by progressive structural change. Crown dieback, limb failures and changes to root architecture become more common as trees age. This doesn't mean the trees should be removed — many mature trees are structurally sound and ecologically valuable — but it does mean they deserve professional structural assessment rather than being left to chance. We assess mature trees using recognised arboricultural frameworks and advise on proactive management to extend their safe useful life.
Tree root systems in Davidson are a common source of property damage. On properties with pools, driveways and structures built in the 1970s–80s, roots from large native trees have had decades to grow into paving joints, drainage lines and pool walls. We can assess root impact, advise on root-barrier installation, carry out root pruning where appropriate, or — where the tree genuinely cannot be retained safely — remove it properly and grind the stump below the surface.
Like Belrose and Frenchs Forest, properties along Davidson's western boundary may have trees originating from Garigal National Park. These Crown Land trees require NPWS consent, not a Council permit, for any work — and we identify this as part of our standard site assessment.
