| Green tree frogs, as the name suggests, live in trees, or
at least they used to before a lot 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. |
