What happened in the Mackenzie Basin was that instead of the tussock recovering, a whole lot of different weed species outgrew the native tussock, and, in fact, the only way to manage it without application of all kinds of horrendous sprays was to allow the stock to graze. That was a great surprise to LINZ officials, and it was a great surprise to the Government majority. It was such a surprise they've conveniently forgotten that.
