Why should we save the bilby?

Why are bilbies better than bunnies?

While rabbits are busy eroding the landscape with their digging, bilbies are constructing spiral-shaped burrows that help keep the ecosystem in balance. In addition to providing shelter, these three metre long diggings act as compost pits filled with decomposing plant material and germinating seeds.

Are bilbies rabbits?

The greater bilby, a threatened marsupial with rabbit-like ears, digs burrows that provide habitat for dozens of species, a new study says. Australia’s own “Easter bunny,” a burrowing marsupial with rabbit-like ears, is even more crucial to the ecosystem than we thought.
