    Brief

    This two-year funded study (2026-2028) contributes to the Species Recovery Programme's Raised Bog Lagg Restoration project, focusing on four protected species: Large Yellow Sedge, Rosy Marsh Moth, Argent and Sable Moth, and Window-winged Sedge. The project requires comprehensive ecohydrological surveys to understand the peatland's historical development and current hydrological status, assess how past modifications have impacted habitats and species populations, and identify areas of hydrological damage. Key deliverables include a detailed restoration plan that addresses lowland raised bog and fen habitat rehabilitation within the Site of Special Scientific Interest, incorporates climate change and sea level rise resilience measures, and maximizes conditions for the four target species to recover and thrive. The work involves background research, full field season fieldwork, hydrological modeling, and the design of interventions to restore natural water processes and create sustainable habitats.
