North America Marine Protected Areas Network

To assess the environmental conditions of marine protected areas (MPAs), experts developed an Ecological Assessment Scorecard methodology, which distills large amounts of complex technical and traditional/local ecological knowledge about MPA conditions. These scorecards are an easy yet powerful tool for MPA managers to share evidence-based ecological information about water, habitat and living resources. The first 10 MPA ecological scorecard sites are located in the Bering Sea to Baja California Region (B2B) region. Additional sites are being added by the countries as time and funding permits. The scorecard for each of the MPAs is based on standard questions about three key themes: water, habitat and living resources, to describe environmental health. Conditions for each ecosystem element addressed by the questions were defined on a five-point scale, ranging from superior (best it could be) to critical (worst it could be). Trends in conditions were likewise defined in five categories ranging from rapidly improving to rapidly diminishing (likely to reach a different state in five years) and stable (unlikely to change beyond normal variation). Initially 14 questions were used, and this was revised to 12 after the first 10 MPAs were scored. Files Download为评估海洋保护区（Marine Protected Areas，MPAs）的环境状况，专家团队开发了一套生态评估记分卡（Ecological Assessment Scorecard）方法，该方法可提炼并整合海量关于海洋保护区状况的复杂技术知识与传统/本土生态知识。此类记分卡是一款简便且功能强大的工具，便于海洋保护区管理人员分享基于实证的水体、生境与生物资源相关生态信息。首批10个海洋保护区生态记分卡监测点位于白令海至下加利福尼亚区域（Bering Sea to Baja California Region，B2B）。后续将有更多监测点在时间与资金允许的情况下由各国陆续增设。每份海洋保护区的记分卡均基于针对三大核心主题的标准化问题搭建，分别为水体、生境与生物资源，用以描述生态环境健康状况。问卷所覆盖的每项生态系统要素的状况，均采用5分制进行评级，评级区间从最优（达到最佳状态）至极差（达到最差状态）。状况变化趋势同样分为五类，从快速改善到快速恶化（预计五年内将发生显著状态变化），以及稳定（不太可能超出正常波动范围发生改变）。该记分卡最初设置14个问题，在完成首批10个海洋保护区的记分评估后，调整为12个问题。文件下载
