1.5 Ghost Pingo Excavation update – September 2023

In August 2023 four ghost pingos were excavated on two separate privately owned landholdings in the Brecks close to Norfolk Wildlife Trust’s Thompson Common nature reserve.

In August 2023 four ghost pingos were excavated on two separate privately owned landholdings in the Brecks close to Norfolk Wildlife Trust’s Thompson Common nature reserve. This follows on from the successful excavation of 10 ghost pingos on Norfolk Wildlife Trust owned Watering Farm between 2020 and 2022. The excavations were overseen by a group of experts, including from Norfolk Ponds Project, University College London and Norfolk Wildlife Trust, and included conservationists and geologists. The work builds on learnings from the previous excavations and focusses on excavating material from the ponds to re-expose sediment and seeds layers within the pingo. It is hoped that these will then germinate and could allow the pingo to quickly re-establish with a wide range of plant species. Following excavation, the restored pingos are surveyed for plants and invertebrates the following summer, and all of the learnings will be recorded in guidance at the end of the project to assist further future restorations.
