It's a bit crazy in NZ due to the mamamal invasion, we have ~4000 endangered species and we are only trying to do something about 300-400. NZ was a weird place where there was virtually no mamamals just mostly birds that didn't have many predators ( other than some giant eagles, where the best response was to stay as still as possible). As a result much of our wildlife have strong scents they use to find each other. Then the rodent mamamals came along and the stinky native species are easy to find, and thir defence is to stay as still as possible. So Carnage ensued. One of our defences is a poison called 1080, which is a synthentic version of a nartually occuring poison ( Sodium fluoroacetate ). It has a unique property of being very toxic to mamamals and not very toxic to most NZ birds and insects, so ideal for NZs situation. The poison itself is pretty brutal on mamamals. But it has proven very effective. However, there is a kind of "antivax" backlash to the poison and a lot of misinformation which has slowed down the use of 1080. So we are living in a weird state of trying to protect what we can while a vast amount of native species are getting annhilated.
