46 acres of marsh, totally overun with invasive spartina, and with rails.

46 英亩的沼泽地，完全被入侵的大米草和铁轨淹没。

Yeah, this is pretty much what we call a monoculture of the invasive spartina.

是的，这几乎就是我们所说的入侵大米草的单一栽培。

In fact, the spartina genus is the dominant plant found in salt marshes.

事实上，米草属是在海碱地带发现的主要的植物。

In higher marsh areas you're likely to find a spartina commonly called salt meadow hay.

生活在地势高的叫做海蒲草。

You can find one type of spartina, salt marsh cordgrass, growing in low marsh areas.

这个属中，生活在地势低的海碱地带的一般叫做海泽琴弦草。

27. If you pull up a spartina, you might even notice some reddish mud on some of the roots.

如果你拔起一株大米草，你甚至还能发现一些粘在根部的红色泥土。

So how is the spartina able to survive in an environment that would kill most plants?

这样的话，为什么米草属的植物的生活范围能够覆盖所有其他植物不能适应的地带呢？
