Abstract

Constructions of offshore wind farms over 15,000 km² are planned on the continental shelf - home to the indigenous critically endangered kelp Laminaria abyssalis and are currently under technical evaluation by the Brazilian environmental authorities (the Brazilian Institute of Environment and Renewable Natural Resources, IBAMA). Construction, maintenance and routine activity near the facilities are expected to intensify the anthropogenic pressure on the kelp's restricted habitat (33,000 km²). Monitoring conducted since 2022 by the global RESTORESEAS project has highlighted the danger of a major reduction in the effective niche of L. abyssalis, raising concerns about its possible functional extinction. Immediate remapping of kelp beds combined with marine forest restoration strategies are essential to prevent irreversible loss and secure current biodiversity to face future climate changes.

海上风力发电场威胁到濒临灭绝的巴西海带：呼吁采取紧急行动保护自然

计划在大陆架上建造面积超过15,000平方公里的海上风力发电场，这是当地极度濒危的海带海带的家园，目前正在接受巴西环境当局（巴西环境和可再生自然资源研究所，IBAMA）的技术评估。设施附近的建设、维护和日常活动预计将加剧对海带有限栖息地（33,000平方公里）的人为压力。全球RESTORESEAS项目自2022年以来进行的监测强调了L. abyssalis有效生态位大幅减少的危险，引发了对其可能功能性灭绝的担忧。立即重新绘制海带床，结合海洋森林恢复战略，对于防止不可逆转的损失和保护当前的生物多样性以应对未来的气候变化至关重要。

期刊介绍： Ocean & Coastal Management is the leading international journal dedicated to the study of all aspects of ocean and coastal management from the global to local levels. We publish rigorously peer-reviewed manuscripts from all disciplines, and inter-/trans-disciplinary and co-designed research, but all submissions must make clear the relevance to management and/or governance issues relevant to the sustainable development and conservation of oceans and coasts. Comparative studies (from sub-national to trans-national cases, and other management / policy arenas) are encouraged, as are studies that critically assess current management practices and governance approaches. Submissions involving robust analysis, development of theory, and improvement of management practice are especially welcome.
