Data_Sheet_1_A Review of the Opportunities and Challenges for Using Remote Sensing for Management of Surface-Canopy Forming Kelps.docx

Surface-canopy forming kelps provide the foundation for ecosystems that are ecologically, culturally, and economically important. However, these kelp forests are naturally dynamic systems that are also threatened by a range of global and local pressures. As a result, there is a need for tools that enable managers to reliably track changes in their distribution, abundance, and health in a timely manner. Remote sensing data availability has increased dramatically in recent years and this data represents a valuable tool for monitoring surface-canopy forming kelps. However, the choice of remote sensing data and analytic approach must be properly matched to management objectives and tailored to the physical and biological characteristics of the region of interest. This review identifies remote sensing datasets and analyses best suited to address different management needs and environmental settings using case studies from the west coast of North America. We highlight the importance of integrating different datasets and approaches to facilitate comparisons across regions and promote coordination of management strategies.

地表冠层形成的大型藻类构成了生态、文化和经济至关重要的生态系统基础。然而，这些海藻森林作为自然动态系统，也面临着来自全球和地方的多种威胁。因此，迫切需要能够使管理者及时可靠地追踪其分布、丰度和健康状况变化的工具。近年来，遥感数据获取能力显著提升，此类数据成为监测地表冠层形成大型藻类的一项宝贵工具。然而，遥感数据的选取和分析方法必须与管理部门的目标相匹配，并针对目标区域的物理和生物特性进行定制。本综述通过北美西海岸的案例研究，确定了最适合满足不同管理需求和环境保护设置的遥感数据集和分析方法。我们强调了整合不同数据集和方法的必要性，以促进地区间的比较并推动管理策略的协调。
