Frogs are particularly important to human beings because they are an ‘indicator species’ – they let us know if there is something wrong with the air, water or earth around them.
Like all our native Australian species, frogs are doing it tough as cities take over from wild habitat. Creating a special habitat in your garden for frogs is an easy thing to do and it will really help our frogs! Different frogs like different habitats so you need to learn a little about what frogs are native in your area and decide what kind you want to attract. The south-west of Western Australia is home to around 30 species of frogs and the easiest way of identifying these secretive creatures is as the scientists do – by their calls!
Don’t speak frog? No problem, this great froggie site will help you out! Head out at night and listen to or record as many sounds as you can find, then you can identify them at home.
Location, Location, Location
Find a place in your garden that is suitable for a pond or bog. The perfect location will have a wet area, as well as access to filtered sunlight, shade and shelter. Make sure it is not a busy place as there might be too much activity to make frogs feel safe.
Wet Area
Once you have picked a spot, you will need to decide on the wet area. Not all frogs like deep water – some prefer bogs or soaks. Ponds can be purchased brand new or you can be creative and make one out of recycled materials such as an old bath, sand tray, or even an old bucket! Dig a hole, place your pond in it and fill with water. If you want a shallower or more boggy environment then also fill all or parts of the pond with dirt and/or stones.
Shelter
Good shelter – whether natural or artificial – is essential in your frog-friendly garden. Natural shelter includes branches, rocks, logs and leaf-litter placed around the wet area. These provide spaces for frogs to sit or hide in/under. Please don’t remove them from the bush as they may already be another animal’s home. Artificial shelter includes holed bricks or PVC-piping, which provide a sturdy frog haven.
Plants
Surround your wet area with native plants. They are more suited to your local area than introduced plants and often require less water. Local plants attract local insects, which in turn attract frogs. Suitable water plants in your pond, such as rushes or sedges, provide shelter and help keep the water clean and oxygenated.
A Balanced Ecosystem
The perfect frog habitat has the right balance of plants and animals. Plants filter the water, frogs eat the insects and tadpoles feed on the rotting vegetation.
Buy one or two native, frog-friendly fish from a pet store to control mosquito larvae (but don’t use goldfish or Mosquito Fish as they will gobble up your frog eggs).
No Chemicals
Frogs drink and breathe through their skin which means they are very sensitive to chemicals in their environment. Avoid using chemicals and (non-organic) fertilisers in and around your whole garden as they may harm frogs. Use environmentally-friendly fertiliser alternatives.
