Wild honeybees in Europe nest in trees, rocks, and hollow walls, accounting for about one-sixth of all colonies (Magnific). The International Union for Conservation of Nature (IUCN) has classified these wild honeybee populations in the EU as "endangered" for the first time, based on a study by the University of Hohenheim in Stuttgart and Agroscope in Zurich. Published in Conservation Science and Practice, the research predicts a 56% decline in free-living Apis mellifera populations in the EU over the next decade.
