The Great Barrier Reef World Heritage Area in Queensland, Australia contains globally significant seagrasses supporting key ecosystem services, including habitat and food for threatened populations of dugong and turtle. We compiled 35 years of data in a spatial database, including 81,387 data points with georeferenced seagrass and species presence/absence, depth, dominant sediment type, and collection date. We include data collected under commercial contract that have not been publicly available. Twelve seagrass species were recorded. The deepest seagrass was found at 76 m. Seagrass meadows are at risk from anthropogenic, climate and weather processes. Our database is a valuable resource that provides coastal managers and the global marine community with a long-term spatial resource describing seagrass populations from the mid-1980s against which to benchmark change. We address the data issues involved in hindcasting over 30 years to ensure confidence in the accuracy and reliability of data included.

综合澳大利亚昆士兰大堡礁世界遗产区 35 年的海草空间数据

澳大利亚昆士兰的大堡礁世界遗产区拥有全球重要的海草，支持关键的生态系统服务，包括受威胁的儒艮和海龟种群的栖息地和食物。我们在空间数据库中编译了 35 年的数据，包括 81,387 个数据点，其中包含地理参考海草和物种存在/不存在、深度、主要沉积物类型和收集日期。我们包括根据商业合同收集的尚未公开的数据。记录了 12 种海草。在 76 m 处发现了最深的海草。海草草地面临着人为、气候和天气过程的风险。我们的数据库是一种宝贵的资源，可为沿海管理者和全球海洋社区提供描述 1980 年代中期海草种群的长期空间资源，以此作为基准变化。我们解决了 30 多年来涉及后报的数据问题，以确保对所包含数据的准确性和可靠性充满信心。
