The issue of wildlife entanglement in everyday items is a pressing concern for Australia's native species, with devastating consequences. It's a complex problem that demands attention and action from all of us. Here's a deep dive into this critical topic, exploring the causes, impacts, and potential solutions.
The Scale of the Problem
The numbers are alarming. In New South Wales alone, approximately 3,500 wildlife entanglement cases are reported annually, with flying foxes accounting for a staggering two-thirds of these incidents. Grey-headed flying foxes, listed as vulnerable under national environment laws, are particularly susceptible to entanglement in backyard nets and barbed wire in regional areas.
The impact extends beyond flying foxes. Entanglements affect a wide range of species, including kangaroos, platypus, raptors, and gliders. Lisa Palma, CEO of Wildlife Victoria, emphasizes the preventable nature of these emergencies, highlighting the role of everyday human activities in causing harm.
Everyday Culprits
Fruit Tree Netting
Backyard netting, a common practice for protecting fruit and vegetables, poses a significant threat to wildlife. Hungry animals, especially flying foxes, birds, and possums, are drawn to the fruits and flowers, only to become ensnared in large-aperture nets with mesh sizes greater than 5mm. Jasmine Vink, an ecologist, describes the horror of witnessing entangled flying foxes, their wings slowly dying due to constriction.
Safer alternatives exist. Wildlife Victoria recommends smaller mesh sizes and cross-weave designs. Fruit tree protection bags, which shield some branches while leaving others accessible to wildlife, are also encouraged. White or light-colored materials are easier for animals to see at night, and nets should be taut and regularly checked.
Fishing Gear and Hair Ties
Aquatic debris, including fishing gear and human rubbish, contributes to entanglement cases, particularly for platypus in urban waterways. Dr. Geoff Williams of the Australian Platypus Conservancy highlights the dangers of fishing line, which can cause horrendous injuries by cutting through the skin. Hair ties, especially elasticated ones, are a growing concern, as they can easily get swept into waterways and ensnare platypus.
Barbed Wire Barrage
Outside urban areas, barbed wire fences present a serious risk to wildlife, especially kangaroos. Wildlife Victoria rescued over 800 kangaroos from fences in the past year, emphasizing the need for solutions. Jasmine Vink points out the ubiquitous presence of barbed wire and its devastating impact on flying foxes in north Queensland.
The majority of entanglements occur on the top strand of fences. Solutions include replacing the top strand with plain wire or installing reflective or brightly colored poly tape or reflective discs to enhance visibility.
Taking Action
If you encounter trapped or entangled wildlife, avoid approaching or touching the animal to prevent stress. Contact your local wildlife rescue or use the International Fund for Animal Welfare's wildlife rescue app to find a licensed carer. Flying foxes should only be handled by trained professionals with proper protective equipment.
Looking Ahead
Addressing wildlife entanglement requires a multifaceted approach. By adopting wildlife-friendly practices, such as using appropriate netting and disposing of fishing gear responsibly, we can significantly reduce the number of native animals injured or killed. Governments and organizations are also playing a crucial role through initiatives like net swaps and the installation of disposal bins for fishing line.
In conclusion, the issue of wildlife entanglement in everyday items is a call to action for all Australians. By raising awareness, implementing solutions, and fostering a culture of environmental responsibility, we can protect our native species and ensure a harmonious coexistence with nature.
