EAGER: The 2010 Recensus of the BCI 50 Hetare Plot

许多热带树木都是长寿的，因此长期数据对于记录和了解热带森林的动态至关重要。由于热带森林在全球碳循环中发挥着巨大作用，而且气候变化对这些生态系统的潜在影响，了解热带森林的动态正变得更加重要。巴罗科罗拉多岛森林动态项目在25年的时间里对一块50公顷的地块进行了6次普查，产生的数据为森林动态和社区生态提供了独特的见解。该项目将对这块50公顷的土地进行第七次为期5年的普查，这将是对热带森林动态进行时间最长的大规模研究。该项目的学术价值来自长期数据集的价值，它将提供对热带森林动态的洞察，以及它在测试与热带森林多样性有关的一系列假说方面的使用。来自这些普查的数据构成了重要的更广泛的影响，因为科学家可以公开获得这些数据，用于非商业用途。正在进行的国际合作和学生培训是更广泛的影响。

Many tropical trees are long-lived, thus long term data are critical to document and understand the dynamics of tropical forests. Understanding tropical forest dynamics is becoming even more important because of the large role tropical forests play in global carbon cycling and because of the potential impact of climate change on these ecosystems. The Barro Colorado Island Forest Dynamics Project has conducted 6 censuses of a 50 ha plot over a 25 year period, generating data that have provided unique insights into forest dynamics and community ecology. This project will conduct a seventh 5-year census of the 50 ha plot, adding to the longest running large scale study of tropical forest dynamics. The intellectual merit of the project comes from the value of the long term data set, the insights it will provide into tropical forest dynamics, and its use in testing an array of hypotheses related to tropical forest diversity. The data from these censuses constitute an important broader impact because they are publicly available to scientists for non-commercial use. An ongoing international collaboration and student training are additional broader impacts.
