EMPA Marsh Plain Vegetation and Epifauna Surveys

The overall goal of the Estuary Marine Protected Area (EMPA) Monitoring Program is to
establish a monitoring framework, including data collection, analysis, synthesis, and
reporting to determine the health of estuaries in California and the efficacy of MPA
designation in estuaries. A key element is the development of a standardized monitoring
protocol that can be used not only by the MPA program, but by any program aimed at assessing
estuary function, condition, or health to provide data that can be easily compared across
systems and between programs. A robust condition assessment framework for estuaries should be
able to accommodate the underlying differences in estuarine structure and form, while still
allowing comparable intra-estuary comparisons of health and condition. The purpose of this
project was to develop a standardized approach to monitor and assess the functions (key
species abundance, diversity, structure, function, and integrity) of estuarine ecosystems. As
part of the initial phases of the program, we developed standard protocols to assess key
estuarine features across different estuaries, coupled with standard data templates and
guidance on analysis, synthesis, and reporting, focused on four guiding principles:
flexibility, comparability, interpretability, and practicality. We developed 14 SOPs and
piloted the framework at 15 estuaries in 2021. Monitoring has continued since 2021 and has
expanded to include new SOPs and new sites. For more details on the EMPA program and

河口海洋保护区（Estuary Marine Protected Area，EMPA）监测计划的总体目标是建立一个监测框架，涵盖数据收集、分析、综合与报告，以评估加利福尼亚州河口的健康状况及海洋保护区（MPA）在河口划定的成效。该计划的核心要素是制定标准化监测协议，此协议不仅可用于MPA项目，还适用于所有旨在评估河口功能、状态或健康状况的项目，从而提供可跨系统、跨项目轻松比较的数据。一个稳健的河口状况评估框架应能适应河口结构与形态的内在差异，同时仍允许对健康状况和状态进行具有可比性的河口内部比较。本项目旨在开发一种标准化方法，用于监测和评估河口生态系统的功能（包括关键物种丰度、多样性、结构、功能及完整性）。作为该计划初始阶段的一部分，我们制定了评估不同河口关键特征的标准协议，并配套了标准数据模板及分析、综合与报告指南，重点围绕四大指导原则：灵活性、可比性、可解释性和实用性。2021年，我们制定了14项标准操作程序（SOPs）并在15个河口试点应用该框架。自2021年以来，监测工作持续开展，并已扩展至纳入新的标准操作程序（SOPs）和新站点。有关EMPA计划及框架的更多详情，请访问https://empa.sccwrp.org。
