But how many of us think about biosecurity as we head off to the beach for summer? If you’re planning … [Read more...] about Mammal-free islands – a biosecurity challenge
Often when predators are eradicated from an island, it’s the first stage in planned reintroduction of native species to the sanctuary, but 26 years ago when the last introduced mammals removed from Burgess Island, the island was simply left, predator-free to recover naturally. Burgess … [Read more...] about Island recovery left to happen naturally
