Wild honeybee populations in the European Union have been classified as "endangered" for the first time, according to a study published in the journal Conservation Science and Practice. The research, carried out by scientists from the University of Hohenheim in Germany and Agroscope in Switzerland, suggests that without the support of beekeepers, wild honeybee numbers in the EU could drop by about 56% over the next decade. These wild bees, which live in natural environments such as tree hollows, rock crevices, and old walls, make up roughly one-sixth of Europe's total honeybee population. Wild honeybees often interact with managed honeybees, which are kept by beekeepers. For example, young queen bees from beekeeping operations sometimes mate with male bees, or drones, from wild colonies. Swarms of managed bees may also settle in natural habitats. Dr. Patrick Kohl from the University of Hohenheim noted that wild honeybees have high genetic diversity, which is important for their ability to resist diseases and adapt to environmental changes. In some parts of the United States, wild bee populations have even developed resistance to the Varroa mite, a harmful parasite that can destroy bee colonies. Despite their ecological importance, there is still limited information about the distribution, population size, and health of wild honeybees across Europe. The study examined survival rates from known nesting sites in several countries and found that wild honeybee populations vary greatly by region. While some areas in central Europe face serious threats, stable populations have been found in England. However, many wild colonies depend on beekeepers to survive, as their numbers are declining. The researchers stressed that the loss of wild honeybees affects more than just genetic diversity; it also disrupts ecological processes such as pollination and the survival of other species that rely on honeybee nests. They urged the recognition of wild honeybees as a key part of biodiversity and called for specific conservation efforts. Dr. Benjamin Rutschmann from Agroscope pointed out that the presence of stable wild honeybee populations indicates a healthy habitat, which requires old trees with hollows, varied food sources, and natural structures. The International Union for Conservation of Nature (IUCN) has classified wild honeybees as "endangered" based on this study. However, the overall status of the species in Europe is listed as "insufficient data" due to the lack of comprehensive information. Factors contributing to the decline include habitat destruction, human activity, parasites, pesticide exposure, and modern beekeeping practices that may reduce genetic adaptability.
