Like so many
other wildlife species frog populations are declining due to loss of
habitat and pollution. If you want to encourage frogs into your garden,
plants, moisture and water will make it more attractive to them.
Frogs need a moist
environment to live in and the protection of plants. You can provide this
with a bog garden by digging a hollow in the ground, lining it with strong
black plastic with drainage holes punched in it and backfilling with soil.
This will drain slowly to provide an ideal habitat for moisture loving
plants and moisture loving frogs.
Bog and frog loving
plants include: Dianella caerulea, D. tasmanica, Gahnia sieberiana,
Isolepis nodosa, Restio tetraphyllus and Viola hederacea.
If you want frogs to breed
you will have to provide a pool of water for them. This can be as large or
small as you like (or as space allows) but should be at least 30 to 50
centimetres deep at the centre to ensure the water does not overheat. It
should receive sunlight for at least a few hours a day.
A pond can be made by
digging a hole to the required shape and size and lining with a pond
liner, this method will enable you to fit it in with the existing
surroundings. Alternatively, ready-made pond shells, which are available
in various shapes and sizes, can be used.
Access must be provided for
frogs to enter and exit the pool. This can be achieved with a
log or rocks positioned
to create a slope from the water to the edge of the pool. Water plants
will provide food and shelter for tadpoles but do not over plant, as lack
of sunlight will create an unhealthy water environment.
Water plants include:
Azolla spp., Myriophyllum spp., Nymphoides spp., Restio tetraphyllus, and
Triglochin spp.
Grasses planted around the
pond edge will drape into the water creating a protective canopy for
frogs.
Suitable grasses include:
Cymbopogon ambiguous, Microlaena stipoides, Themeda australis and
Danthonia tenuior.
Other useful
groundcovers: Brachyscome multifida, Hardenbergia violacea and
Hibbertia spp.
Do not put fish in the pond,
as they will eat frog eggs.
Fountains look nice in ponds
but will probably make mince meat out of frog eggs and small tadpoles.
Take care with chemicals,
frogs are sensitive and may eat insects that have been sprayed with
insecticide. |
