A new report has been published to help protect European wetlands. The report focuses on two types of wetlands: peatlands and coastal lagoons. It found that these areas are crucial for the environment, but have suffered significant loss due to human activities.
A new synthesis report titled 'Ecological Characterisation of Peatlands and Coastal Lagoons in Europe' has been published to support the assessment, monitoring, and restoration of European wetlands under EU environmental legislation. The report was prepared in response to a policy request submitted by the Directorate-General for Environment (DG ENV) to the European Commission's Knowledge Centre for Biodiversity (KCBD) and delivered by the Science Service for Biodiversity (SSBD), which is currently under development by the BioAgora project.
The report provides an ecological characterization of two contrasting Annex I habitat groups under the Habitats Directive: inland peat-forming wetlands (Group 7, 'Raised bogs, mires and fens') and coastal lagoons (habitat type 1150). Its findings are intended to inform monitoring and condition assessment under the Habitats Directive (HD), the Water Framework Directive (WFD) and the Nature Restoration Regulation (NRR).
European wetlands have undergone substantial historical loss, with an estimated 80% of the wetland area present a century ago no longer extant and more than half of remaining peatlands drained. Despite their comparatively limited spatial extent, peatlands are estimated to store nearly one-third of global soil carbon, while coastal lagoons account for approximately 13% of the global coastline and support disproportionately high levels of biological productivity and biodiversity.
The report identifies the hydrological regime as the dominant control on the functioning of both habitat groups. In peatlands, a persistently high and stable water table sustains the anoxic conditions that suppress decomposition and allow peat to accumulate. When the water table falls—most often through drainage—peat oxidizes, subsides and compacts; vegetation and microbial communities shift; and fire risk increases.
In coastal lagoons, freshwater-marine exchange, hydrographic and associated biological connectivity, and physico-chemical gradients regulate hydrodynamics, sediment transport, nutrient availability, community structure and biological productivity. They are associated with substantial natural variability and spatiotemporal heterogeneity independent of anthropogenic pressure.
Why It Matters
This report is important for India because it highlights the importance of protecting wetlands, which can help mitigate climate change and support biodiversity. India has its own wetland areas, such as the Sundarbans mangrove forest, that need to be protected.
Key Facts
- The report focuses on two types of European wetlands: peatlands and coastal lagoons.

- Peatlands store nearly one-third of global soil carbon, while coastal lagoons account for 13% of the global coastline.
- The hydrological regime is the dominant control on the functioning of both habitat groups.
- Drainage and land-use conversion are major causes of wetland degradation.
Key Terms
- Habitats Directive
- A European Union law that protects and conserves natural habitats.
- Water Framework Directive
- A European Union law that sets standards for water quality and management.
