Green tree frogs, as the name suggests, live in trees, or
at least they used to before most of the trees were replaced by downpipes. This
little fellow was found in a drum-design owl box in a park about 40m from a designated
frog-breeding area. Without any natural hollows in the area, and little litter on
the ground, it must have been the best she could find. The box was about 6 metres
above the ground. |

It would seem logical that these large frogs must have difficulty
surviving where there are no man-made structures and no hollows large enough for them to
shelter in.
We have made a few frogboxes as described below, although
few have yet been erected and none long enough to prove anything.
The boxes are made from a 250mm length of 90mm PVC
stormwater pipe mounted vertically. Both ends are capped with standard PVC end
fittings; the base glued on and the top pushed on with a smear of Vaseline. The end
caps have a raised ridge around the edge so that the lid traps rainwater. A 7mm hole
is drilled in the lid to allow the rainwater to run into the pipe. A 7mm overflow
hole is drilled in one side so that the pipe holds about 25mm of water. A horizontal
entry slot 75mm x 20mm is cut a little way above the overflow hole, at the back of the
box. The box is positioned about 65mm out from the tree to allow access to the
entry slot. |
