reintroducing wolves

美國北部的皇家島國家公園的狼群,因氣候暖化無法透過結冰後的湖面往返島嶼,在缺乏捕獵者的情況下,公園內最大島嶼上的駝鹿數量大增,導致植被快速消失。國家公園管理局用直升機空降從加拿大引入的野狼到公園內,希望有助控制駝鹿的數量。

in the Isle Royale National Park, wolves cannot travel between islands when the lake’s surface is frozen in the winter because of global warming. without predator, the number of moose increased and plants are disappearing in fast speed. The National Park Service
reintroduced wolves from canada and airdropped them on the island in order to control the moose population.
