Globally, peatlands are essential terrestrial carbon stores that can provide nature-based solutions for climate change mitigation. One of the least well-understood types of peatlands in the world are wet woodlands (peatlands with substantial tree cover). Wet woodlands were once a common habitat type across the UK, but after years of disturbance and destruction, only an estimated 50-70,000 ha remain. Despite their scarcity, these ecosystems could be substantial, long-term carbon sinks due to their peat-forming characteristics. However, climate change and increasing development will determine whether these ecosystems become a source of carbon in the future. We are seeking an individual who will i) quantify contemporary carbon dynamics and fluxes, ii) determine past landscape dynamics using paleoenvironmental techniques, iii) link current and future carbon sequestration to ecohydrological variables (i.e., water table depth), and iv) make comparisons to other wetland ecosystems (e.g., tropical peatlands).

在全球范围内，泥炭地是必不可少的陆地碳储存库，可以为减缓气候变化提供基于自然的解决方案。湿地林地（有大量树木覆盖的泥炭地）是世界上最不为人所知的泥炭地类型之一。潮湿的林地曾经是英国各地常见的栖息地类型，但经过多年的干扰和破坏，估计只剩下50- 70，000公顷。尽管这些生态系统稀缺，但由于其形成泥炭的特性，它们可能是大量的长期碳汇。然而，气候变化和日益增长的发展将决定这些生态系统未来是否会成为碳源。我们正在寻找一个人，他将i）量化当代碳动态和通量，ii）使用古环境技术确定过去的景观动态，iii）将当前和未来的碳封存与生态水文变量（即，地下水位深度），以及iv）与其他湿地生态系统进行比较（例如，热带泥炭地）。
