日本語
本研究は、北欧の12の沿岸湿地（放牧あり・なし）において、植物と土壌中の有機炭素貯蔵量を定量し、放牧と環境勾配が炭素貯蔵に与える影響を評価した。土壌炭素が全体の大半を占め、放牧地で非放牧地より高い値を示した。放牧は植物群落を変化させ、間接的に土壌炭素貯蔵に影響を与えた。これらの知見は、北欧沿岸湿地の持続可能な管理と炭素貯蔵能力の保全に重要である。
English
This study quantified organic carbon stocks in plants and soil across 12 grazed and ungrazed Nordic coastal marshes, assessing how grazing and environmental gradients shape carbon storage. Soil carbon dominated total stocks and was higher in grazed sites. Grazing altered plant communities and indirectly affected soil carbon. Results inform sustainable management of Nordic marshes for carbon storage.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではブルーカーボン生態系（海草藻場等）の炭素貯留機能に注目が集まっている。本研究は放牧管理という人為的撹乱が炭素貯蔵に与える影響を解析しており、日本の干潟・湿地管理にも示唆を与える。ただし、直接日本の政策や開示基準に結びつく内容ではない。
In the global GX context
Blue carbon ecosystems are gaining attention globally for their climate mitigation potential. This study provides empirical evidence on how grazing management affects carbon stocks in coastal marshes, contributing to the broader understanding of land-use impacts on natural carbon sinks. While focused on Nordic systems, the findings are relevant for global blue carbon conservation and management strategies.

📄 Abstract（原文）
Abstract. Coastal marshes are key habitats contributing to organic carbon (OC) storage but remain understudied in Nordic regions regarding Blue Carbon processes. This study quantified OC stocks in above- and below-ground plant biomass and in the top 50 cm-soil across 12 grazed and ungrazed marshes, spanning a major environmental gradient, and assessed how biotic (plant communities, livestock grazing) and abiotic (soil properties, environmental conditions) drivers shape OC storage. Soil OC stocks accounted for ∼ 73 % of total OC in grazed sites and ∼ 63 % in ungrazed ones and was higher in grazed sites (99.7 ± 57.9 Mg ha−1) than in ungrazed sites (78.2 ± 44.2 Mg ha−1). Grazing and the large-scale environmental gradient strongly structured plant communities, partly by regulating reed (Phragmites australis), prevalent in ungrazed sites. Abiotic soil properties were major large-scale drivers of soil OC storage, while grazing affected soil OC storage indirectly through plant composition. Soil OC increased with finer textures, whereas vegetation and grazing effects were variable and locally expressed. Aboveground OC stocks were reduced by grazing, both directly through biomass removal and indirectly by reducing reed dominance. Belowground OC stocks were driven by plant community composition and indirectly by grazing effects on vegetation. Root biomass was concentrated in the top 15 cm in grazed sites and deeper (15–50 cm) in ungrazed sites, reflecting contrasting plant strategies. Overall, soil OC stocks in Nordic coastal marshes fall within the lower range of global estimates. These findings highlight the need to consider soil processes, grazing and environmental gradients in the sustainable management of Nordic coastal marshes and their carbon storage potential.
