"I caught three brown snakes in one backyard with two males fighting over a large female."Mr Carstens said.
"If they don't have the habitat, they're going to share it with us, so we're going to be seeing a lot more snakes."
"The classic adage [that] 'the only good snake is a dead snake' is wrong and it's illegal to kill protected species,"Dr Hodgson said.
"Snakes don't want to interact with us because, ultimately, we're the big scary predator,"he said.
