澳大利亚最近在一份报告中发布了世界物种数目的最新估计。在这份报告由Arthur Chapman为澳大利亚生物资源研究准备的。该份报告称每年有超过2万个新物种被描述。尽管我们目前还没有一个地球生物完整的物种清单，但是这份报告使我们世界生物编目的工作又向前迈进了一步。据估计，我们地球上已经被描述的生物物种数目有达到200万种。而目前网络生物大百科全书EOL网站已经有了150万种生物的基本网页。下面是报告的内容纲要：
在这份报告的前言中，作者这样写到：
In Australia and around the world, biodiversity is under huge and growing pressure. The pressures are pervasive and chronic in many places — invasive species, habitat loss and climate change in particular. But there’s also good news. Every day we are making exciting new discoveries about the breadth and depth of Australia’s biodiversity. Since the first edition of the Numbers of Living Species in Australia and the World was produced in 2006, we’ve discovered 48 reptiles, about 200 new fish species and 1,184 flowering plants.
Understanding of the global significance of Australia’s biodiversity is also on the increase. This comprehensive
review of the endemism of Australia’s plants and animals shows that a greater percentage of our plants and animals
are found nowhere else in the world. Reptile endemism has jumped from 89 to 93 per cent, mammals from 83 to 87 and frogs from 93 to 94. And close to 92 percent of our vascular plants, up from 90 per cent, are unique to Australia. It is vital that we forge new and innovative ways of conserving and protecting this unique biodiversity at a landscape level.
Harnessing core science and knowledge bases, like this report, will be key to creating new ways of meeting
Australia’s biodiversity challenges. Importantly, they provide a benchmark for assessing and monitoring the future effects of climate change on Australia’s biodiversity. As we move into the International Year of Biodiversity in
2010, Australia has the opportunity to show global leadership in biodiversity conservation. This report, the only one of its kind in the world, is a positive start.
