A high proportion of Australian birds and mammals are dependent on hollows in trees for nesting and shelter. The number of suitable nesting hollows in trees is declining throughout Australia. Natural hollows in trees suitable for nesting by native animals can take over 120 years to form in native trees. With the demise of many natural hollows due to tree clearing and firewood collection, it is important to provide alternatives.
A number of native birds and mammals frequently come into urban areas to feed from native trees planted in suburban gardens. However they are unable to breed due to the lack of sufficient nesting hollows.
These nest boxes for native animals and birds are the result of decades of experience and trials by wildlife experts at Latrobe University with field testing in their Wildlife Reserves and elsewhere.
