大象贸易信息系统，通常被称为ETIS，是《濒危野生动植物种国际贸易公约》（CITES公约）用于追踪象牙和其他大象制品非法交易的强制执行工具。
ETIS由TRAFFIC代表CITES缔约方进行管理和运作，旨在确定非法大象制品贸易的趋势和变化，并评估这些趋势和变化是否与《CITES公约》的大象保护相关决定有关。ETIS的主旨和CITES另一个相关项目大象非法猎杀监测项目（MIKE）的主旨相同，通过一个覆盖非洲和亚洲的实地系统来追踪野生大象的盗猎行为。

的数据与记录现存在于ETIS数据库中
《CITES公约》缔约方在1997年第十次缔约方会议上通过Conf. 10.10号决议首次强制执行了ETIS。它记录了自1989年以来在世界各地查获的象牙和其他大象制品的详细情况。
查获数据由一系列附属数据库所组成。这些附属数据库对执法努力和效率、报告率、治理、经济因素、国内象牙市场和其他基于时间和具体国家的背景变量。自2002年以来，ETIS对数据库内数据进行了全面的分析，结果用于每次CITES缔约方会议上进行讨论。

Understanding ETIS
This brochure provides a useful introduction and overview of the context behind ETIS, and the way in which the analysis is conducted.
establishment and ongoing development
The development of ETIS is an ongoing and successful collaboration between TRAFFIC and statisticians Mr. Bob Burn and Dr. Fiona M Underwood, both previously at the University of Reading. In particular, the expert ivory analysis and development of the bias adjustment method were developed by Bob and Fiona in collaboration with TRAFFIC. Much of ETIS’ recent development was conducted under a UK Government Darwin Initiative project, and the ETIS analyses for CITES CoPs and Standing Committee reports were originally carried out by Bob and are now led by Fiona.
ETIS是如何保护大象的
data collection
A dedicated, centralised database concerning elephant ivory related enforcement actions such as seizures and arrests helps paint the clearest picture available of the global landscape of illegal ivory trade.
Records spanning decades enable analysts to map trends and emerging trade flows, helping to predict key areas of concern as they develop and identify where renewed international attention is most needed. This in turn ensures that informed and effective conservation policy is reached by CITES parties, helping to protect elephants from threats as they emerge.

支持CITES
Conf. 10.10号决议规定所有的缔约方……应在象牙或其他大象制品被查获的九十天内提供相关信息。在这方面，《CITES公约》缔约方被视为ETIS的“数据提供方”。
除了提供这些数据与相关信息外，《CITES公约》缔约方还可以使用该平台来审查或下载与他们有关的ETIS数据、检索ETIS数据的摘要报告，并获得可能随时可被使用的其他内容。ETIS的常规报告、政策建议与分析会定期向CITES提交。

象牙专家分析
可靠的数据和准确的分析是ETIS建议的核心。
要准确评估非法象牙贸易趋势，就需要为我们的监测提供同样准确的概念框架，特别是考虑到象牙查获率和汇报率会因国家或地区而产生很大差异。
因此，我们开发了一个严格的“偏差调整”模型来调整这种波动，下面是它的工作原理。
