Where do bees live?
Bees live on every continent except Antartica. They live in deserts, the tropics, and everything in between. The highest diversity of bee species can be found in Mediterranean-style climates.
Often people think bees all live in hives with queens, workers, and drones. Only honey bees do this, and they represent just a few species out of the estimated 25,000 types of bees worldwide. Most of our native bees nest in the ground, and others nest in wood cavities or inside old hollow stems.
Where has all their habitat gone?
Throughout the world, there have been significant losses in bee habitat. In the United States, grassland prairies—once rich habitats supporting pollinators and wildlife—are now functionally non-existent. Recent surveys suggest close to a 99.9% loss over the last 150 years, primarily due to increasing agricultural intensification. In the United Kingdom, roughly 97% of native wildflower habitats have been lost since the 50s for the same reason.
Similar losses are occurring in other ecosystems that once supported pollinators. Increasing human populations are driving ever-increasing conversion of wild areas for farmland, suburban, and urban purposes. With these areas come other threats to bees, including increased pesticide use, poor habitat management practices (mowing down wildflowers before they are able to set seed), and other varied problems that come with living alongside increasingly dense human populations.
Sadly, even increasing honey bee densities are having an impact on our many thousands of native bee species. There are tens of thousands of honey bees in a hive, which means that each hive requires a plethora of floral resources to support so many more bees. If you’re a beekeeper, you can help by providing large swathes of additional flowering plants to feed your bees, so that competitive pressures do not reduce native bee populations.
What can I do to help?
Bees have simple needs: food and shelter. Good food for bees means a diverse banquet that’s available during all seasons of the year—even very early spring and late fall. Shelter means spots for bees to live, plus the raw materials they need to construct their nests. Providing a perfect habitat for bees—in your own garden, balcony, workplace, or community—is one of the most critical actions you can take to help bees of all kinds right away.
