i) Wildlife-friendly fences

With fences being encouraged for stock control and to protect vegetation and sensitive areas, landholders can make fences more wildlife-friendly by applying the following rules of thumb:
• If possible, use (white) horse-sighter wire on the top strand and white caps on steel posts, or treated pine posts.
• Leave 30 cm between the top wire and the next one down. This is important to avoid kangaroos catching and trapping their legs between the two top wires.
• Don’t use barbed wire. If existing fences have barbed wire, consider taking that wire out, particularly on the top strand. If this is not practically possible, sections of poly pipe split lengthways could be placed over sections of the top barbed wire.
• Keep fences at a moderate height — about 4 foot or 1.2 m.
• Keep the bottom wire at least 6 inches (15 cm) off the ground — this allows passage for wombats, echidnas and the determined kangaroo.
• Moderate-height ringlock may be OK if kept at least 15–20 cm off the ground. Better are six-wire fence or horse-sighter wire fence design.
• Permanent electric fencing can form a significant barrier to wildlife movement. Echidnas can be electrocuted against low-level live wires.

Wetlands or dams fenced too close to the water can prevent some species of bird from landing and taking off.
If in doubt, discuss wildlife concerns with a fencing contractor, fencing manufacturer or wildlife specialists.  Further information can also be found at Wildlife Friendly Fencing.
