In an area littered with decades-old pika droppings.

而那里遍布着几十年前的鼠兔粪便。

But the pika itself is a very tasty morsel.

但鼠兔本身也是可口的美食。

Especially further south, where loftier summits allow pikas to roam higher to escape rising temperatures.

尤其是更靠南的地区，那里山峰更高，使鼠兔可以前往更高处躲避高温。

In such a frugal environment, the pika's farming helps to kick start the food chain.

在如此俭朴的环境，鼠兔的耕作有助于推动整个食物链。

It's relatively pristine habitat, in the center, rather than the edge, of historic pika territory.

那是一个相对原始的栖息地，是历史上鼠兔领地的中心，而非边缘。

Despite summer snowstorms, the pika, a relative of rabbits and hares, is perpetually eating and gathering grass, and digging burrows for its family.

虽然遇到夏季暴风雪，鼠兔，一种家兔和野兔的亲属，依旧不断啃食、收集青草，为家人挖掘地穴。
