On New Zealand’s North Island, a conical snow-capped volcano ringed by dark green forest rises above dairy pasture. The often-snowcapped peak of Mount Taranaki is the centerpiece of Egmont National Park. A circular piece of land—with a 9.6-kilometer (6-mile) radius from the volcano’s summit—was first formally protected as a forest reserve in 1881. With some subsequent additions, it became New Zealand’s second national park in 1900.
