Carbon in wet woodlands

The forgotten forests: improving our understanding of wet woodlands as carbon-dense ecosystems is a research project measuring the amount of carbon in wet woodlands.

Key features: The research measures the amount of carbon aboveground (in the wood of trees) and belowground (in the peat and tree roots) in wet woodland, and links these to woodland characteristics, such as tree age and species. The project will provide the first estimates of carbon stocks in wet woodland.

Why it’s important: To help tackle climate change and to get maximum carbon storage from tree planting, the right type of trees need to be planted in the right places. Policies on tree planting have largely ignored wet woodlands, and very little research has been done on these systems so we don’t know how their re-establishment can help national tree-planting schemes. Understanding more about wet woodlands and their potential for carbon accumulation above- and belowground will help us improve decisions around land-use and afforestation for climate change mitigation.

Location: Peat-forming wet woodlands in the Broads National Park, Norfolk, UK.

Who’s involved: The research is led by Dr Alice Milner (Royal Holloway University of London), Dr Emily Lines (University of Cambridge) and Prof Andy Baird (University of Leeds); and involves project partners from the Broads Authority, Natural England and the Ted Ellis Trust. The project is funded by the Woodland Trust, with contributions from the Broads Authority and Royal Holloway University of London. Read about it on the Woodland Trust website.

Wet woodlands as a nature-based solution to climate change

The wetter the better? Wet woodlands as a nature-based solution to climate change is a research project looking at the potential of wet woodlands for climate change mitigation.

Key features: This project will assess the vulnerability of wet woodland ecosystems (and their carbon storage potential) to future climatic and land-use change including sea-level rise and land management activities. The benefits of preserving these ecosystems are likely to be substantial, given what we know about organic-rich environments. Understanding more about wet woodlands and their potential for carbon accumulation above- and belowground will help us improve decisions around land-use and afforestation for climate change mitigation and their role as a nature-based solution to climate change.

Why it’s important: This project will provide initial data on the climate mitigation potential of these ecosystems. This data can be used to inform potential future payment categories for wet woodland ecosystems under the Woodland Carbon Code and the Peatland Code. Stakeholders and land managers will benefit from this research. For example, an improved understanding of wet woodland functioning will allow for better integration of these ecosystems in land-use planning, providing insight into the importance of their conservation and potential restoration.

Location: Slapton Ley, Devon, UK.

Who’s involved: The research is led by Dr Scott J Davidson (University of Plymouth), Dr Paul Lunt (University of Plymouth), in collaboration with Dr Tom Roland (University of Exeter); and Slapton Ley Field Studies Council. The project is funded by the Seale-Hayne Education Trust.

Monitoring changes in wet woodlands

The Broadland Ecohydrological Observatory (BEO) is a wetland monitoring site collecting long-term data on a floodplain fen wet woodland.

Monitoring hydrological changes in wet woodland

Monitoring water level and water flow in wet woodland

Key features: Monitoring started in 2017 using a series of instruments to collect hourly data on the meteorological (e.g., temperature, rainfall) and hydrological (e.g., water level, salinity) changes. The data are used to understand how this freshwater ecosystem functions, how it changes over time, and responds to flooding from the river and tidal (saline) surges from the coast.

Why it’s important: Sea-level rise caused by climate change is a potential major threat to coastal freshwater peatlands. The ingress of salty water could destroy their existing plant communities and their carbon sink function. There is considerable research in how coastal saltwater ecosystems – such as salt marshes and mangroves – might adjust to sea-level rise but less attention has been given to coastal freshwater wetlands, such as floodplain fens and wet woodlands. Data on long-term changes (over years and decades) will improve our understanding of the threats and potential solutions to these important ecosystems.

Location: Wheatfen, Norfolk UK.

Who’s involved: The BEO was established by Dr Alice Milner (Royal Holloway University of London) and Prof Andy Baird (University of Leeds) in partnership with the Ted Ellis Trust; and collaborates with a range of academic and non-academic institutions.
