热带雨林的物种丰富给生态分析带来了困难。通过定义生态物种群，其成员具有决定森林结构和组成的重要特征，可以有效地简化这一问题。许多这样的分类已经出版，但很少有适当的解释。由于缺乏精确的定义，这些术语很混乱。基于种子萌发和幼苗建立，我们将树种简单地划分为两个类群或行会，先锋和非先锋（或顶极）。在每个行会中都有连续的变化，我们建议按成熟时的高度任意细分。我们认为这种分类适用于所有热带雨林。
The species richness of tropical rain forests creates difficulties for ecological analysis. It may usefully be simplified by defining ecological species groups whose members share characteristics of importance for determining forest structure and composition. Many such classifications have been published, but few are properly explained. The terminology is confused from lack of precise definitions. We propose a simple division of tree species into two groups or guilds, pioneer and non-pioneer (or climax), based on seed germination and seedling establishment. Within each guild there is continuous variation and we recommend arbitrary subdivision by height at maturity. We believe this classification to be applicable in all tropical rain forests.
