Frog Ponds: Most of us are not able to provide habitat for the world’s threatened animal species but there is one group, which gardeners may assist. Frogs are under threat throughout the world and loss of habitat is one of the factors contributing to their demise. A frog pond is easy to construct, adds interest to your domestic landscape, increases the range of plants that may be cultivated and most importantly will provide a haven for the frog species in your area. We have a number of frog ponds at Yallaroo and they are the home to a number of frog species. These ponds are situated near our house, which sits on top of a windswept hill, not the ideal environment for frogs. Never the less these intrepid amphibians have found our ponds and are living and breeding happily. The three most popular construction materials are: concrete, pre-formed fibreglass and rubberised pond liners. We favour rubberised liners. Concrete ponds are expensive and often leak. Fibreglass ponds are more expensive than liners.
The five photographs illustrate the method of construction. Photo 1: After some exercise the hole appears. Rocks and other sharp objects are removed from the hole. Photo 2: The hole is lined with newspaper. Sand may be used instead of newspaper. At the time of construction we had more paper than sand. Photo 3: The liner is in place. There should be at least a 10 centimetre (4 inch) overlap, of liner, around the pond. At this stage the pool is filling. Photo 4: The pool is lined with rocks. Photo 5: The pond a few months after completion. The liner for this pond cost about $150.
Our ponds are about two metres long, one metre wide and about 30 centimetres deep. In future our ponds will be at least 60 centimetres deep. We have found that a depth of 30 centimetres is too shallow and water lilies do not develop properly. Their leaves and flowers are smaller in shallow ponds. Ground covers are planted around the pond and their stems grow into the water. This curtain of vegetation allows easy entry and exit from the pond. See frogs and planting frog ponds for more information.
