Wild Honey Bees Declared Endangered in the European Union

Many people associate honey bees with neatly arranged hives, jars of golden honey, and hardworking beekeepers. But beyond managed apiaries lies another world, one where honey bees still live as they did for millions of years, in hollow trees, stone crevices, and other natural habitats. These are Europe’s wild honeybees, and they have just been officially recognised as endangered within the European Union.

A Long Relationship with Humans

The western honey bee (Apis mellifera) has been linked with human activity for thousands of years. Ancient civilizations, including the Egyptians, were known to keep bees in primitive hives to collect honey and beeswax. Over time, modern beekeeping evolved into an intensive practice, supporting both agriculture and pollination on a global scale.

Today, however, this close relationship has created two distinct groups of the same species, the managed honey bee colonies that live under human care, and the wild colonies that survive independently in nature. While genetically similar, their lifestyles and challenges are vastly different.

Managed vs. Wild Populations

Managed colonies have received considerable scientific attention, especially since widespread hive losses began alarming beekeepers in the early 2000s. These declines led to global efforts to study the causes, from pesticides and diseases to habitat changes. Yet, the wild counterparts of these bees remained largely overlooked until recently.

Over the past few years, researchers have begun documenting wild honey bee colonies across Europe, from Ireland’s forests and the UK’s countryside to the woodlands of Germany, France, Poland, and Italy, and even urban settings like Belgrade in Serbia. The question driving much of this work has been whether these colonies can sustain themselves naturally, without the aid of humans.

Connecting Research Across Borders

In 2020, a global initiative known as Honey Bee Watch was launched to unite these research efforts. This collaboration brought together scientists and conservationists to better understand the ecology of wild honeybees and reassess their conservation status. Working closely with the International Union for Conservation of Nature (IUCN), the team evaluated how these populations are faring in the wild.

This effort contributed to the latest update of the European Red List of Bees, a comprehensive assessment of nearly 2,000 bee species. Until recently, wild Apis mellifera populations had been classified as “data deficient” due to the lack of clear evidence separating truly wild colonies from those that might have escaped managed hives.

A New Way to Define ‘Wild’

The latest assessment adopted a more ecological rather than genetic approach to defining wild bees. Since honey bees are not fully domesticated, beekeepers cannot entirely control breeding or prevent gene flow between wild and managed colonies, the focus shifted to their behaviour and independence.

Wild honeybees, under this new definition, are those that live without human management and can maintain stable populations without relying on escaped or introduced colonies. This framework has allowed scientists to better estimate their conservation status across the continent.

A Troubling Picture

Europe now has the lowest density of wild honeybee colonies in the world. Managed hives outnumber them by a vast margin, and recent research shows that wild populations are steadily declining. Factors such as habitat loss, disease, invasive parasites, and genetic mixing with managed bees have all contributed to this downward trend.

As a result, the IUCN has officially listed wild honey bees as “Endangered within the European Union.” However, for other parts of Europe, including the Balkans, the Baltics, Scandinavia, and Eastern Europe — data remain too limited for a full assessment.

Why It Matters

Protecting wild honeybees goes beyond saving a single species. These bees play an essential role in maintaining biodiversity and ensuring food security through pollination. Wild colonies, having adapted to survive without human assistance, may also hold valuable genetic traits that make them more resistant to parasites and environmental stresses.

Recognising their endangered status is a crucial step forward — one that highlights the need to treat wild honeybees as native wildlife deserving of protection and research. Ensuring their survival will not only benefit ecosystems but also strengthen the future of managed honeybee populations that humanity depends upon.
