Old Trees Are Ecosystem Gold

老树在生态系统种发挥着巨大的作用

Well, lots of people recognize that as humans get older they tend to have less and less children...trees do it the other way around.

“那么,很多人都意识到,人类随着年龄的增长,他们的孩子往往会越来越少,而树木则完全相反。”

David Lindenmayer. He studies conservation, landscape ecology and biodiversity at the Australian National University College of Science in Canberra. On January 26th he spoke to Scientific American Editor in Chief Mariette DiChristina when they were both at the World Economic Forum in Davos.

大卫·林登迈尔表示道。他在位于堪培拉的澳大利亚国立大学理学院进行自然保护、景观生态学以及生物多样性方面的研究。1月26日,他在达沃斯经济论坛上,与《科学美国人》的主编玛丽特·迪克里斯蒂娜进行了交谈。

DL: "What happens is that the older some of these really big old trees get, the more seeds they produce and the more germinants they're likely to have. So it's actually the polar opposite of what we see with humans and most other animals, so really quite extraordinary."

大卫·林登迈尔:实际情况是,树木生长得越久,它们落下的种子可能也就越多,因而它们的种子发芽长出小树苗的可能性也就越大。所以,实际上这与在我们人类以及多数其它动物身上看到的截然相反,所以非常的特别。

Mariette DiChristina: "And how about the number of older trees that we have today, how does that look?"

玛丽特·迪克里斯蒂娜:那我们如今有多少老树,它们现状如何?

DL: "It's quite a distressing situation, because in many, many forests and woodland and other ecosystems around the world, populations of large old trees are declining very, very quickly. And this matters because a lot of biodiversity, a lot of carbon, a lot of key ecosystem processes are associated with those really big, old trees."

大卫·林登迈尔:实际情况相当令人痛苦,因为在全球各地的许多森林、林地和其它生态系统中,大型古树的数量正在迅速减少。这一点非常重要,因为这些古老的参天大树事关生物多样性、碳吸收以及很多关键的生态系统进程等情况。

MD: "Is there something we can do about this?"

玛丽特·迪克里斯蒂娜:那么,有什么是我们能做的吗?

DL: "Absolutely there is. We can make sure we grow more forest, we can make sure we protect the big trees that we have now, and we can make sure that we don't do things that really put a lot of pressure on those trees. Straight out, just cutting them down - we should not be cutting down really big, old trees anymore."

大卫·林登迈尔:绝对有啊。我们可以确保扩大森林覆盖面积;我们可以确保我们能保护现有的大树;我们可以确保不做会危害这些树的事。直截了当的说,就是别砍树,我们不能再砍掉这些参天老树了。
