Canopy-forming kelp forests are globally recognized as one of the most structurally complex foundational ecosystems, which play an important role in maintaining marine food webs, buffering shorelines against erosion and contributing to carbon and nitrogen cycling. In coastal British Columbia, kelp forests have cultural relevance as historical navigation routes and as habitats for important food sources, particularly for coastal First Nations. Today, the cumulative effects of a warming climate, coastal development and sedimentation, threaten marine species including kelps, which are recognized as ecologically significant species of priority in Canada. Loss of this critical habitat will greatly impact commercially valuable marine fisheries and at-risk or endangered species, resulting in large-scale ecological shifts and the loss of a way of life for many coastal communities. In BC, the current status of bull and giant kelp species, and their fate is unknown, due to insufficient research within the context of local environmental stressors and global-regional climate drivers of change. This NSERC Alliance Partnership is strategically aligned to increase the regional knowledge-generating capacity to tackle large-scale data analysis and knowledge mobilization. By employing historical data and remote sensing technologies with big data analytics, this project aims to determine the long-term distribution patterns of canopy-forming kelp forests and define spatial-temporal resilience to environmental and biotic drivers. Anticipated outcomes and advancements will result in social, economic and environmental benefits for Canadians. For example, the identification of critical habitats or "hots-spots" of kelp resilience, areas at high risk for kelp loss and areas of potential target for restoration, will be integrated into ecosystem-based management strategies to inform Marine Protected Areas, spatial marine planning, kelp harvesting, and fisheries habitat management. The framework developed by this Alliance can be expanded to the Canadian East and Arctic coasts and can fuel the design and development of a sustainable, ocean-based blue economy, as part of Canada's Blue Economy Strategy, as well as related Blue Carbon initiatives.

树冠形成的海带森林在全球范围内被认为是结构上最复杂的基础生态系统之一，在维持海洋食品网中起着重要作用，使海岸线免受侵蚀并有助于碳和氮气循环。在不列颠哥伦比亚沿岸，海带森林具有文化相关性，作为历史航行路线，是重要食物来源的栖息地，尤其是对于沿海原住民而言。如今，温暖的气候，沿海发育和沉积物的累积影响威胁着包括海带在内的海洋物种，海带在加拿大被认为具有生态意义的优先级。失去这种关键栖息地将极大地影响商业上有价值的海洋渔业和处于危险或濒危物种，从而导致大规模的生态转变以及许多沿海社区的生活方式。在卑诗省，由于在当地的环境压力源和全球区域气候变化驱动因素的背景下的研究不足，公牛和巨型海带物种的现状及其命运尚不清楚。这种NSERC联盟合作伙伴关系在战略上是一致的，以提高区域知识生成的能力，以应对大规模数据分析和知识动员。通过使用大数据分析的历史数据和遥感技术，该项目旨在确定树冠形成的海带森林的长期分布模式，并定义对环境和生物驱动因素的时空弹性。预期的结果和进步将为加拿大人带来社会，经济和环境福利。例如，鉴定海带弹性的关键栖息地或“热点”，海带损失的高风险和潜在恢复目标领域的区域，将被整合到基于生态系统的管理策略中，以告知海洋保护区，空间海洋规划，海带收获和渔业栖息地。该联盟开发的框架可以扩展到加拿大东部和北极海岸，并可以为加拿大蓝色经济战略的一部分以及相关的蓝色碳计划推动可持续的，海洋蓝色经济的设计和开发。
