A new project aims to protect the British Swallowtail butterfly, which is threatened by habitat loss and climate change. Researchers from Anglia Ruskin University are collaborating with Jimmy’s Farm & Wildlife Park and Nature's SAFE to explore cryopreservation techniques to aid conservation efforts. The British Swallowtail's population has declined significantly, but recent conservation efforts have stabilized it. The project could enhance long-term conservation strategies for this butterfly and other pollinators.
