19 Returning to the applicants' issues with the tree and the tests under s 10(2). In the matter of the staining of clothes from insect droppings, in Robson v Leischke [2008] NSWLEC 152) at 189, Preston CJ states that
" the specification of the tree as being a cause of damage to property or injury to any person excludes damage or injury directly caused by animals, such as mammals, birds, reptiles or insects, which may be attracted to a tree or use it as habitat."
In this matter, the issue about insect droppings apply to this determination by Chief Justice Preston.
20 Similarly, the build up of leaf litter on the roof or on the paving will not ordinarily provide the basis for ordering the removal of a tree. As outlined in Barker v Kyriakides [2007] NSWLEC 292 and subsequent tree dispute principle available on the Court's website, it is expected that some level of external housekeeping and maintenance is normal for people who live in leafy urban environments and who benefit from the environmental and aesthetic benefits that trees provide. This tree would have been well established when the applicants purchased their property.
