Trees within the boundaries of a private property may require Council approval to be pruned or removed, depending on the circumstances.
If you are concerned about a tree on a neighbouring property, the best way to sort the issue out is to discuss it with your neighbour. Your neighbour may not be aware that there is an issue.
If a tree or shrub is on the footpath, the road side outside a property boundary or in a park or reserve then it is on Council land. As a result, planting, pruning or removal of trees or shrubs on Council land requires written consent from Council.
The clearing of native vegetation within Wollondilly requires consent unless it meets an exemption.
