These tussock leaves are iced-up after a harsh frost. Tussocks have so many leaves that their total surface area can be very large. The water droplets in fog can be intercepted by the long fine leaves of a tussock, capturing a considerable amount of water. Two-thirds of Dunedin’s water supply comes from the 20,882-hectare Te Papanui Park on the Lammerlaw Range in eastern Otago, where billions of tussock leaves are capturing water from fog.
