From the coasts to the plains, bird flu could threaten not just birds – but their homes
From raucous honeyeaters to top predators, Australia’s birds are vital to nature. But now bird flu is here
A bird flu outbreak in Australia has raised concerns about the potential impact on ecosystems beyond just birds and mammals. Conservationists have warned that the loss of birds could lead to a "miserable" future for trees, as birds play crucial roles in many ecosystems. From pollinating flowers and spreading seeds to keeping trees free of sap-sucking insects, birds contribute to the health and balance of various habitats.
In Australia, birds act as soil turners, seed distributors, and nutrient cyclers in wetlands, woodlands, and shrublands. Their absence could lead to reduced germination rates, less diverse plant life, and the potential decline of unique species such as cassowaries, pigeons, and finches. If bird populations decline significantly, it could result in large trees dying, particularly in eucalyptus forests, and lead to a decrease in genetic diversity.
Bird flu could also affect scavengers and predators, further disrupting the delicate balance of ecosystems.
