世界各国必须衡量其在实现关键生物多样性目标方面的进展。这方面的一个重要例子，即《生物多样性公约》的2010年目标，即将实现。确定的目标是到2010年大幅度降低生物多样性丧失的速度。然而，在多大程度上有数据，特别是热带国家的数据，可以用来表明生物多样性的变化，目前对生物多样性变化的了解在多大程度上真正反映了全球情况？虽然热带地区的物种丰富度最高，但生物多样性数据的丰富度却向两极倾斜。这不仅对准确反映生物多样性的全球指标提出了重大挑战，而且对根据此类立法负责衡量本国对生物多样性影响的各个国家也提出了重大挑战。我们使用四个全球生物多样性数据集来研究生物多样性数据的覆盖范围，并研究目前的努力在解决这一差异方面的有效性，以及各国在2010年及以后可以做些什么。最后，我们提出了一些活动，可能会提供动力，改善热带国家的生物多样性监测。
Nations around the world are required to measure their progress towards key biodiversity goals. One important example of this, the Convention on Biological Diversity's 2010 target, is soon approaching. The target set is to significantly reduce the rate of biodiversity loss by the year 2010. However, to what extent are the data, especially for tropical countries, available to indicate biodiversity change and to what extent is current knowledge of biodiversity change truly a global picture? While species richness is greatest in the tropics, biodiversity data richness is skewed towards the poles. This not only provides a significant challenge for global indicators to accurately represent biodiversity, but also for individual countries that are responsible under such legislation for measuring their own impact on biodiversity. We examine the coverage of biodiversity data using four global biodiversity datasets, and look at how effective current efforts are at addressing this discrepancy, and what countries might be able to do in time for 2010 and beyond. We conclude by suggesting a number of activities which might provide impetus for improved biodiversity monitoring in tropical nations.
