To provide an empirical foundation for estimates of the Amazonian tree diversity, we recently published a checklist of 11,675 tree species recorded to date in the region (ter Steege H, et al. (2016) The discovery of the Amazonian tree flora with an updated checklist of all known tree taxa. Scientific Reports 6:29549). From this total of plant records compiled from public databases and literature, widely used in studies on the Amazonian plant diversity, only 6,727 tree species belong to the first taxonomically-vetted checklist published for the region (Cardoso D, et al. (2017) Amazon plant diversity revealed by a taxonomically verified species list. PNAS 114:10695-10700). The striking difference in these two numbers spurred us to evaluate both lists, in order to release an improved Amazonian tree list; to discuss species inclusion criteria; and to highlight the ecological importance of verifying the occurrence of "non-Amazonian" trees in the region through the localization and identification of specimens. A number of species in the 2016 checklist that are not trees, non-native, synonyms, or misspellings were removed and corresponded to about 23% of the names. Species not included in the taxonomically-vetted checklist but verified by taxonomists to occur in Amazonia as trees were retained. Further, the inclusion of recently recorded/new species (after 2016), and recent taxonomic changes added up to an updated checklist including 10,071 species recorded for the Amazon region and shows the dynamic nature of establishing an authoritative checklist of Amazonian tree species. Completing and improving this list is a long-term, high-value commitment that will require a collaborative approach involving ecologists, taxonomists, and practitioners.
为了为亚马逊地区树种多样性的估计提供一个经验基础，我们最近发表了一份清单，列出了迄今为止该地区记录的 11675 个树种（ter Steege H 等人，2016 年，《亚马逊地区树种的发现与所有已知树种分类群的更新清单》，Scientific Reports 6：29549）。从这些从公共数据库和文献中汇编的植物记录中，有广泛用于研究亚马逊植物多样性的记录，只有 6727 个树种属于该地区首次发表的经过分类学验证的清单（Cardoso D 等人，2017 年，《经分类学验证的物种清单揭示的亚马逊植物多样性》，PNAS 114：10695-10700）。这两个数字之间的显著差异促使我们评估这两个清单，以便发布一个改进的亚马逊树种清单；讨论物种列入标准；并强调通过对标本进行定位和鉴定来验证该地区“非亚马逊”树种的出现的生态重要性。在 2016 年清单中，有许多不是树的物种、非本地种、同义词或拼写错误的物种被删除，约占名称的 23%。没有列入经过分类学验证的清单但被分类学家确认为在亚马逊地区出现的树种被保留。此外，列入最近记录的/新物种（2016 年后）和最近的分类学变化，使这份更新的清单包括了 10071 种记录在案的亚马逊地区树种，并展示了建立一个权威的亚马逊树种清单的动态性质。完成和改进这个清单是一个长期的、高价值的承诺，需要生态学家、分类学家和实践者的合作。
