PlanSA says its regulated and significant-tree rules apply where the overlay operates and defines relevant trees using trunk circumference measured at the stated height. Tree-damaging activity can include removal, lopping, topping and substantial root damage and generally requires development approval unless a current exemption applies.
PlanSA’s maintenance-pruning guidance says approval is not needed only where the work is unlikely to affect health or appearance; examples requiring approval include removal of more than 30% of the crown or repeated pruning within five years under the described circumstances.
The Minister’s exempt-species notice is versioned, with a current notice published in April 2026, so campaigns should link customers to the current list rather than hard-code a species claim. Gawler, Tea Tree Gully, Marion and Onkaparinga involve different councils and property conditions, making council and address essential fields. The provider should distinguish an arborist assessment, development application support, pruning, removal, stump grinding and replacement planting.
Neighbour ownership, public trees, electrical proximity and wildlife remain separate checks. A visual defect or branch drop cannot support an unrestricted emergency-removal promise without the current statutory pathway and safe inspection.
