of our environment and protecting our local frog populations from decline.
Frogs (and tadpoles):
- are an important link in the food chain
- help with insect control
- are an indicator of the health of micro-systems (due to their
permeable skin and sensitivity to change or chemicals)
- help control algae levels in ponds
What do frogs need?
A place to hide, from predators and hot, dry conditions
Frogs shelter in many places depending on whether they are ground-dwelling or arboreal (tree climbing). Frogs naturally prefer cooler, moist places. This can be achieved by the careful placement and partial burying of terracotta pots or ceramic pipes. Provide thick leaf litter with rocks and logs to hide in, and digging spots for burrowing frogs.
Adult frogs are insect eaters. It is relatively easy to attract insects to your frog area.
- Install solar lights that turn on at dusk to attract moths and other flying insects at the right time for the frogs.
- Good selection and density of plants to encourage insect life providing a variety of food options for your resident frogs.
A place to breed
Most frogs require a permanent source of moisture to successfully breed such as a pond, dam or river. Providing clean water will in turn provide a stable breeding site. Different frog species have different breeding habitat requirements, so read up on your local frogs and their specific requirements.
Build it (right) and they will come!
Before you begin, look around as you may be surprised by what you find and where. Particularly take notice of the natural lay of the land. You can use low-lying areas to your advantage; these make ideal hideaway spots for frogs that are enhanced by strategic positioning of logs, rocks and other suitable hides. Extend these features into water if possible, they are essential shelter for frogs from predators and weather. Remember to check for the location of pipes before digging! There are no single
rules for constructing a frog suitable habitat and the adage of ‘many roads lead to Rome’ rings true.
- Water areas may be a hazard to small children so you may need to make plans to reduce risk and provide child-friendly fencing.
- Frogs can be quite noisy with the onset of rain or the breeding season so choose the location of your frog-friendly area carefully!! You may need to select a spot well away from your
and your neighbour’s windows.
- Domestic animals can be a major threat to the survival of frogs and other native wildlife. Keep free-ranging chickens, dogs and cats out of your frog-friendly areas.
- Position your pond two-thirds in shade or use plants to provide shade (avoiding deciduous and toxic plants). Sunshine is needed for plants and to provide algae for tadpole food, too
much is detrimental to water quality.
- Remember never to use pesticides on insects around your house as these may then poison your frogs. Let your frogs do the work on pest control!!
- Vary pond depth to include deep (cool) areas for the warmer months and shallow areas for easier frog entry and exit. This also allows tadpoles of different species to select their preferred water temperatures, increasing likelihood of morphing into frogs.
- Keep Cane Toads out! This means creating a 60cm high physical barrier, and extending this into the soil if your pond is at ground level. Or simply monitor your pond regularly and remove Cane Toad eggs when found.
- Avoid steep walls as small frogs may drown if they cannot exit easily.
- Fill the pond with rainwater. If not possible, use tapwater treated to remove chlorine and fluoride.
- Provide loose substrate to support aquatic plants and invertebrates (another food source for frogs).
- Densely plant shallows and provide a variety of emergent, submerged and floating plants, preferably native species.
- Most fish eat frog eggs and/or tadpoles, however smaller species of the following native fish groups are frog-friendly and will help with mosquito control: blue eyes, smelts, hardyheads, Galaxias, pygmy perch, rainbowfish, carp gudgeons.
- A well-designed frog-friendly area will attract local native frogs. DO NOT relocate eggs or tadpoles from other areas to your pond, this is detrimental to the frogs and against the law. Be patient…they will come!
- Globally frogs and toads are struggling. There have been significant declines related to pollution, loss of habitat, global warming, use of chemicals and the spread of disease, such as Chytrid fungus.
We can all do our bit to help local native frogs to stay ‘common’ and not end up on the threatened species list.
