Aspens have long roots that burrow through the soil.

白杨有着钻透土壤长根茎。

That gave willows, cottonwoods, and aspens a better chance to grow near streams.

这使得杨柳、三角叶杨和白杨有更好机会在溪流附近生长。

The deers' aggressive browsing of young aspen poses a huge threat to Pando.

鹿对小山杨树侵略性掠食给“潘多”造成了巨大威胁。

It's a stand of trees, a field of aspens all clones and all connected at the roots.

它是一片树林，是全部无性繁殖、所有根系连接在一起一片山杨树林。

The sap was rising in the pines. The willows and aspens were bursting out in young buds.

汁液灌满在松树上，嫩芽绽放在柳树上。

So as aspen goes so do all those dependent species. So that's the number one reason.

因此，随着山杨衰落，其它所有依赖物种也会随之消失。这是最重要原因。”

Pando is not an unusual aspen from a genetic standpoint.

从基因角度来看，潘多并不是一种不寻常杨树。

In the Western U.S., the lower 48, aspen, second to riparian systems, are the most biodiverse forests that we have.

在位于国西部下48州，就生物多样性丰富程度来说，山杨林仅次于河岸系统。

And that's a really dangerous situation for aspen because it really depends on continuous growth of the whole clone.

这对山杨来说是非常危险情况，因为山杨非常依赖整体无性繁殖持续增长。

The girl whose family she went with to aspen.

她和她们一家人去了阿斯本。

What is this? the bracelet you lent me in aspen?

这是什么？ -你在阿斯本借给我手镯？

It goes to a single quaking aspen named " Pando" that weighs over 6,000 tonnes — as much as forty blue whales.

这属于一棵名叫 “Pando” 山杨其，重量逾 6000 吨，和40条蓝鲸一样重。

So after a severe fire, the environment is better suited for deciduous tree species like birch and aspen to get a foothold.

因此在严重火灾后，森林环境更适合桦树和山杨等阔叶树立足。

Pando, an 80,000 year-old forest of quaking aspen, is really 47,000 or so genetically identical trees, one single organism growing from the same roots.

Pando，一座八万年前白杨森林，实际上是 47，000 棵左右基因相同树木，从同一根生长出来单一生物体。

So after a severe fire, the environment is better suited for deciduous tree species like birch and aspen to get a foothold. These trees grow much faster.

所以在一场严重火灾之后，环境更适合像桦树和白杨这样落叶树种找到立足点。 这些树长得更快。

Deciduous trees like birch and aspen live for about 100 years, so the team couldn't simply wait for one or two centuries to find out what happens in the forest.

像桦树和白杨这样阔叶树寿命约为100年，所以研究小组不能只是等上一两个世纪来发现森林里发生了什么。

But, thanks to genetic testing, we've learned that this stand of aspen covering 106 acres of land is actually a single clonal organism that grew from a lone seed long ago.

不过，正是由于基因检测，我们发现这片覆盖 106 英亩山杨实际上是由很长时间前一粒种子无性繁殖出来。
