The benefits to these carved hollows are they provide more insulation than there plywood counterparts, more hidden from predators and last a lot longer..
In saying this the plywood nesting boxes are excellent too. And serve as a valuable substitute where carving a hollow is not possible (often).
Head to www.faunature.com.au to check out nesting boxes that you can purchase and either install yourself, or we can install for you.
James Smith (faunature) has been a huge part of the journey arborists have been on to create these hollows for our fauna. Cheers James!
