Why the Honeybee Isn't the One to Worry About
Think of honeybees as livestock. They're an agricultural animal, managed by beekeepers for honey production and crop pollination. While they face serious threats like Varroa mites, associated viruses (such as deformed wing virus), the invasive Asian hornet, Colony Collapse Disorder, and climate change causing colonies to starve over winter, human intervention keeps their numbers stable. In North America, for example, honeybee populations might decline, but beekeepers actively sustain them. Promoting honeybee hives is an agricultural practice, not a strategy for true native bee conservation or overall pollinator biodiversity.
While honeybees are crucial for agriculture, their managed status means their conservation needs differ significantly from wild species. But the widespread public perception, often amplified by popular media, tends to mix up "bees" with "honeybees," overlooking the urgent needs of diverse native bee populations. Conservation biologists and environmental groups often point out that honeybees are a managed species and advocate for a broader understanding of native bee conservation.
The Real Pollinator Crisis: Our Native Bees
The real story of native bee conservation lies with our native and wild bees, many of which are facing serious threats. Unlike honeybees, these species don't have beekeepers treating them for mites or making sure they have enough food through winter.
Take bumblebees, for example, which are native to the Americas, unlike honeybees. Bumblebees and other wild bees pick up mites from blossoms, but they don't get human treatments like formic or oxalic acid. Viral infections carried by Varroa destructor are wiping out many native populations. Worse still, honeybees compete directly with native bees for resources, and they can transmit diseases to them.
Beyond diseases and competition, native bees face immense pressure from habitat loss and pesticide use. Urbanization, monoculture farming, and the widespread use of insecticides, including neonicotinoids, decimate wild bee populations. These chemicals can directly kill bees or impair their navigation and foraging abilities, leading to colony collapse. Without diverse habitats providing continuous food sources and nesting sites, native bees struggle to survive, making focused native bee conservation efforts more critical than ever.
Native bees also contribute to plant biodiversity in ways that generalist honeybees often don't. For instance, leafcutter bees are highly effective pollinators for plants like alfalfa because of how they interact with the flowers. European honeybees, on the other hand, often bypass pollination by chewing through flower bases just for nectar.
And don't expect honey from most native bees. While some, like Asian honeybees, produce honey, it's often thinner, less concentrated, and ferments more easily than what you get from Apis mellifera. Solitary bees, like mason or leafcutter bees, are also generally docile; they'd rather fly away than sting you.
Supporting Our Native Pollinators: Practical Steps for Native Bee Conservation
So, if you want to make a real difference for native bee conservation, shift your focus to native species and consider these practical steps.
Planting for a Continuous Feast
Native bees need specific plants for their specific nutrients, and they need steady food sources throughout their active periods. Common ornamental flowers often do not provide sufficient nutrients. Focus on planting a variety of local wildflowers that bloom at different times throughout the summer. This ensures a continuous food supply, a cornerstone of effective native bee conservation.
Give Bees a Drink
Bees also require water. A shallow dish with some stacked rocks or marbles provides a safe landing spot for them to drink without drowning.
Avoid Pesticides and Herbicides
One of the most impactful steps you can take for native bee conservation is to eliminate or drastically reduce the use of pesticides and herbicides in your garden and yard. Even "bee-friendly" pesticides can harm non-target insects. Opt for organic gardening practices, embrace natural pest control methods, and tolerate a few weeds, especially if they are native flowering plants.
Building Homes for Native Bees
Many native bees are ground-nesters, while others prefer tunnels. "Bee hotels" can be great, but they need to be designed correctly.
- For mason and leafcutter bees: Sheltered boxes filled with tubes (like Japanese knotweed tubes, though don't grow the plant itself as it's invasive) or wood blocks with variously sized holes. Mason or orchard bees prefer holes 3/16 to 5/16 inch (5-7mm) in diameter.
- For carpenter bees: Holes around 1/2 inch (12-13mm) in diameter.
- A key detail for bee hotels: The holes need to be deep enough to protect the bees from predatory birds. Insufficient depth can turn these well-meaning structures into "bee traps," making them vulnerable.
- For ground-nesting bees: Species like the green metallic sweat bee (observed in Western Oregon by the Oregon State University Garden Ecology Lab) prefer semi-compacted, neutral to slightly alkaline sandy soil, weed-free, such as found in long-term orchards utilizing softer insecticide chemistries.
Dandelions: Friend or Foe (Depending on Where You Are)
There's an interesting regional difference: in North America, dandelions are not native and aren't a great food source for native pollinators. But in Europe, particularly places like Hungary, dandelions are native. They serve as a vital early food source, especially for bumblebee queens and mining bees, when other preferred sources are scarce. So, before you let your dandelions grow, consider your local ecosystem.
A Call to Action for Native Bees
The "save the bees" movement is important, but we need to be precise about which bees we're talking about. Honeybees are an agricultural success story, kept stable by human effort. Our native bees, however, are struggling against habitat loss, disease, and competition. Organizations like the Xerces Society are at the forefront of advocating for these vital species. If you want to help pollinator conservation, support the wild, native species in your local area. Plant native wildflowers, provide proper nesting sites, and recognize the difference between a managed agricultural animal and a wild creature fighting for survival – that's where your efforts for native bee conservation will make the biggest impact.
