Abstract

Glaciers, corals, speleothems, peatlands, trees and other natural proxy archives are essential for global climate change research, but their scarcity and fragility are not equally recognised. Here, we introduce a rapidly disappearing source of palaeoclimatic, environmental and archaeological evidence from some 5000 years ago in the Fenland of eastern England to argue for the protection of natural proxy archives. We describe the region's exceptional, yet neglected subfossil wood sources, discuss its multifaceted value for scholarship and society, and outline a prototype for sustainable proxy preservation. Finally, we emphasise the urgency and complexity of conservation strategies that must balance academic, public and economic interests across different spatiotemporal scales.
