Nesting box along the Cooks River in Earlwood.
$200,000 was spent trying to protect wildlife impacted by the Southern Hume Highway Duplication project in Southern NSW. See – http://ab.co/2uDf9fl
587 nesting boxes were installed to replace the 587 trees with natural hollows that were felled as part of major tree clearing between Holbrook and Coolac to build the highway. The nesting boxes were to help the Superb parrot, the Brown treecreeper & the squirrel glider deemed threatened or in need of assistance.
NSW Roads and Maritime Services commissioned the nesting boxes, as well as a 4-year follow-up study to see whether the boxes were being used. The boxes were checked 3,000 times over the four years.
The follow-up study found the project had failed.
“There will be some populations of these species that basically won’t do well now because they won’t have the nesting resources and they won’t have those resources for the next 200 to 300 years. We need to make sure we don’t make those mistakes again.” ~ Professor David Lindenmayer, Australian National University Canberra.
Trees take between 80-150 years to develop hollows, so changes in tree management is needed if hollow-dependent wildlife are to survive. We cannot feel confident that nesting boxes can be offered as a substitute for a natural tree hollow.
No hollow means no breeding. No breeding leads to extinction.

Nesting boxes: what uses them and what doesn’t is still a question requiring a huge amount more research. At least in the example on the Hume Highway, some monitoring is taking place. I know a few spots where boxes have been installed but it seems no one ever checks them for usage.
Strangely, a lot of people have success with a backyard possum box, installed when a possum has been excluded from dwelling in a roof. Probably this is because the animal is still in its own territory.
We had a nesting box in the back yard for a time, which didn’t appear to be attracting any use, but when we took it down it had a champion huntsman spider occupying it!
