Farm dams and constructed wetlands
Dams with aquatic and fringing vegetation provide habitat for more numbers and a greater variety of frog species. Shallower vegetated areas are important for most frogs as they provide opportunities for egg laying and for tadpoles to feed. Dams with little or no fringing or aquatic vegetation provide few opportunities for tadpoles and frogs to feed or breed.
Nearby trees provide hiding and foraging places for frogs like the Peron’s Tree Frog which are often found sitting under bark.
Small and large dips found in paddocks are frequently used by frogs as they move across the landscape. They also provide temporary ponds for breeding. These small habitats are most likely used opportunistically by other species at different times
Creeks with large overflow areas with reeds and other aquatic vegetation can provide suitable locations for the deposition of eggs and tadpole growth. Creek and riparian management are important for frogs. Creeks with incised channels provide little opportunity for the growth of emergent aquatic vegetation resulting in a lack of habitat. The revegetation and addition of snags to creeks can create suitable frog habitat including stream-side pools and aquatic vegetation growth.
Large complex wetlands
Large complex wetlands are of high value for amphibians and other native species. These wetlands consist of creeks or drains which overflow and spread into surrounding vegetation and depressions. Wetlands with a diversity of aquatic and fringing vegetation provide the best habitat for amphibians, especially with logs, earth mounds and rocky areas for food foraging. Within wetlands, the depth of water and hydroperiod very greatly, which provides habitat for a variety of different species.

Recommendations for habitat maintenance – by Alex Knight
Many sites contain good habitat for a diversity of frogs and just require occasional maintenance while others can be improved by active management as suggested below.
- Logs and fallen timber provide important habitat for frogs and other creatures. It is important to leave some areas of timber at dams and creek sites. If it is not possible to leave fallen timber then choose a particular part of the site to leave a fallen log as refuge.
- Resnagging creeks may help the development of shallow slow moving water areas with vegetation which provide frog habitat
- Frogs and tadpoles need aquatic and emergent vegetation in the waterbody. Allow vegetation to grow in wetland or dam shallows. Manage your grazing so that wetland vegetation is not impacted.
- Manage your grazing so that pugging does not occur all around the waterbody or throughout the wetland
- When planning your riparian or wetland revegetation projects don’t tree every part of the site, leave some areas more open so that frogs can bask. Consider the density of planting so that hydroperiod and flow are not adversely affected.
- When planning revegetation projects it is important to consider including the adjacent depressions and floodplain areas that fill up with water occasionally. Frogs use these as breeding sites. Fence off areas with as much width from the top of the bank as possible.
- Use frog-friendly chemicals, for instance choose Biactive roundup
- Use fertilisers and chemicals responsibly. For instance do your soil testing and apply fertilisers at the appropriate variable rates (this will also reduce input costs). Check up on the best practice for your particular management activity and choose the right chemical for the job.
- Remember that many of our frogs are burrowers and look after your soil health in areas adjacent to wetlands.
