• A WWII bomb crater in Walthamstow Marshes, London, has become a thriving pond supporting a diverse ecosystem.
  • Scientists studying areas obliterated by recent Russian blasts in Ukraine are observing how quickly nature begins to heal itself.
  • Small ponds are often underestimated but support a wider range of freshwater plants and animals than large rivers or lakes.
  • Ponds are resilient to pollution because they are too small to receive wastewater, often retaining clean water.
  • Examples from Belgium and the New Forest show how bomb craters can become rich habitats for amphibians and other species.
