角马如何拯救塞伦盖蒂大草原

How Wildebeest Saved the Serengeti

[soft percussive beat]
[轻柔的敲击节奏]
For the next three years,
在接下来的三年里
Tony keeps a close watch on the wildebeest,
Tony密切关注着角马
looking for signs they’re overgrazing the grasslands.
寻找它们过度啃食草地的迹象
But after two more counts,
但在数了两遍之后
numbers remain steady at 1.4 million.
角马的数量稳定在140万只
At that point, we knew
在那时 我们知道
that the system had leveled out of its own accord
生态系统已经自行趋于平稳
And there was no damage to the environment.
并且环境没有被破坏
The wildebeest find their natural balance.
角马找到了它们的生态平衡
But what happens next amazes even Tony.
但是接下来发生的事连Tony都感到吃惊
He and his colleagues witness an incredible transformation.
他和他的同事见证了一场不可思议的转变
[uplifting music]
[令人振奋的音乐]
To our surprise,
令我们吃惊的是
we found that, all of a sudden,
我们发现 突然之间
things started to reconnect with each other
事物之间开始重新建立联系
because wildebeest were eating up the grass,
由于角马不停啃草
there was less fuel,
环境中可燃物变少
and therefore less burning.
因此火灾就少了
That allows young trees to grow.
小树得以生长
Wildebeest, of course, do not eat trees.
当然 角马不会吃树
And that allowed the tree populations to increase.
树木种群也得以增长
Tree populations that probably hadn’t occurred
树木种群可能从十九世纪以来
since the 1800’s.
就没有增长过
Those trees provided more food for elephants,
这些树木为大象
for giraffes and many, many bird species.
长颈鹿和很多很多鸟类提供了更多的食物
And then there are many more predators
食肉动物也更多了
because there’s more food for those, too.
因为它们也有了更多的食物
The wildebeest in their huge numbers
数量庞大的角马
were determining everything else inside the park.
决定着公园里的其他一切
I realized that wildebeest was a keystone.
我意识到角马是关键物种
[dramatic orchestral music]
[激烈的管弦乐]
We had always assumed that keystones
我们以前一直以为关键物种
had to be a predator.
应该是食肉动物
But we realize that a keystone
但现在我们意识到关键物种
could actually be herbivores.
实际上也可以是食草动物
And if removing keystones causes collapse,
如果除去关键物种导致了生态崩溃
returning them leads to rebirth.
那么让它们回归 生态就会复苏
We were seeing a recovery,
我们第一次见证了一场生态复苏
an upgrading of the whole ecosystem for the first time.
一场整个生态系统的升级
[orchestral music]
[管弦乐]
