Between the mainland and Tasmania are a series of small islands that are all that is left of the land bridge that once filled the Bass Strait before sea-level rise flooded the basin around 14,000 years ago. Since European occupation, the environment of these islands has changed dramatically. Large areas of native vegetation have been converted to farmland, native predators have been eradicated, feral cats have been introduced, wallaby numbers have skyrocketed whilst tiny native wood birds are on the road to extinction.

In the Bass Strait Islands, the removal and eradication of wedge-tailed eagles, quolls and Tasmanian devils and the introduction of livestock and invasive predators like cats have brought about drastic declines in native wood bird populations. Could the reintroduction of these native predators help to rebalance this ecosystem?

This week we talk to Matthew Fielding about roadkill, ravens, currawongs and the pros and cons of trophic rewilding, a form of ecosystem management where top-level predators are reintroduced, aiming to restore the natural structure of food webs.
