Plants survive over 100 years in buried 'ghost ponds'
UK-based researchers have found aquatic plants which survived over 100 years in "ghost ponds" buried beneath cropped fields. Ponds buried for 45, 50, and 150 years, when excavated, were colonised in less than six months by native aquatic plants. The study highlights it is possible to "resurrect" these buried habitats from the seeds and eggs stored within their historic sediments.
