Threat to Wildlife and Bio-Diversity

Natural tree hollows provide perfect shelters for many birds, mammals and reptile species; however, they can take from decades to up to 300 years to form enough to allow birds such as parrots and animals such as possums to use them. Unfortunately for our local wildlife, continuous development within our urban spaces is not conducive to allowing hollows to develop naturally or for existing trees with hollows to remain. Loss of established trees due to natural occurrences such as bush fires, for health and safety reasons, aesthetic reasons, or general land clearance and therefore loss of habitat are all threatening bio-diversity in Queensland and Australia as a whole.

Before removing a tree, guidance should be sought from a qualified Consulting Arborist as to whether the tree would be a suitable candidate to become a habitat tree. Ideally a tree’s removal should be a last resort, for example, if there is imminent danger of tree uprooting or falling and causing danger to people or property. A knowledgeable and experienced Arborist will confirm whether the whole tree will need to be completely removed or if part of it can be saved to become a habitat tree thus preserving a great amenity for local wildlife.

Creating Artificial Hollows

Once a tree has been identified by an Arborist as a candidate for artificial habitat creation it is can then be habitat pruned so that it poses no hazard risk to the general public or property. Artificial hollows can also be created by a few differing methods and should only be undertaken by experienced Arborists who have the knowledge and expertise to do the job. As different birds and animals prefer divergent hollow types, it is important to decide upon which kind of species you are hoping to attract to the tree. Consulting with your Arborist, local ecologists and biodiversity officers to decide which would be the best species to target in that particular area would be helpful for the decision making process.

  • The Arborist will identify a suitable location on the trunk for the hollow.
  • A face plate will be cut out of the trunk and lowered to the ground.
  • An entrance hole will be drilled into the faceplate- depending on the size of the targeted species.
  • Screw holes will be drilled into the face plate
  • On the trunk where the face plate has been removed a boring cut will mark out the proposed cavity using a small chainsaw.
  • A hammer and chisel will then be used to create the cavity.
  • An entry hole will be drilled in and the finally the faceplate will be reattached to the trunk.
  • The artificial hollow blends into the tree and therefore it blends into the environment not making it obvious that there are nesting birds or animals in the vicinity.

Nesting Boxes

Another viable option for habitat creation,  is to use nesting boxes placed strategically in trees or on top of poles. Like the artificial hollows, these boxes need to be built to size to attract particular species as well as being predator proof. Nesting boxes can be a DIY project or can be bought from reputable company.
