Below are resources on the above subject so that you can become empowered and educate others. In the very least it's a list and a link you can give to people when the conversation turns deeper.
1) The Bee Apocalypse Was Never Real
Honey bees are not under threat of vanishing. Colony collapse disorder isn't what we think it is.
2) Competition Between Managed Honey Bee and Wild Bumble Bees Depends On Landscape Context
This one's behind a paywall, but you'll see links to other related articles down the page to broaden the discussion. From the abstract that explored two generalist groups (honey and bumble):
Honeybees might outcompete wild bees by depleting common resources, possibly more so in simplified landscapes where flower-rich habitats have been lost....Adding honeybees suppressed bumblebee densities in field borders and road verges in homogeneous landscapes whereas no such effect was detected in heterogeneous landscapes. The proportional abundance of bumblebee species with small foraging ranges was lower at honeybee sites than at control sites in heterogeneous landscape, whereas bumblebee communities in homogeneous landscapes were dominated by a single species with long foraging range irrespective of if honeybees were added or not.
3) An Overview of the Potential Impacts of Honey Bees to Native Bees, Plant Communities, & Ecosystems...
This is from the Xerces Society. Solid summary of all the issues that focuses on working with beekeepers for the best apiary placement.
4) Massively Introduced Managed Species & Their Consequences for Plant-Pollinator Interactions
From the abstract: First, we review the impacts of major insect and plant MIMS on natural comm-unities by identifying how they affect other species through competition (direct andapparent competition) or facilitation (attraction, spillover). Second, we show how MIMScan alter the structure of plant–pollinator networks. We specifically analysed the posi-tion ofA. melliferafrom 63 published plant–pollinator webs to illustrate that MIMS canoccupy a central position in the networks, leading to functional consequences. Finally,we present the features of MIMS in sensitive environments ranging from oceanicislands to protected areas, as a basis to discuss the impacts of MIMS in urban contextand agrosystems.
5) Bees Gone Wild: Feral Honey Bees Pose a Danger to Native Bees and the Ecosystems That Depend on Them
A professor of entomology looks at what happens when honey bees go rogue: "It’s these feral honeybees, especially, that pose a challenge to nearly all native pollinators since honeybees forage throughout the growing season for nectar and pollen from a wide array of flowers, building up vast numbers. When honeybee competition reduces the number and diversity of native pollinators, native plants also can suffer since they may receive less efficient pollination."
6) You're Worrying About the Wrong Bees
Another intro for those dipping their toes into the topic, complete with source material cited at the end.
7) Foreign Bees Monopolize Prized Resources in Biodiversity Hotspot
Here's a study that focuses on southern California -- as you may know, California is one of if not the richest state in native plant diversity. For this study keep in mind that many native bees have evolved to uses specific native plants for pollen to feed their young. "New research from the same team found that honey bees focus their foraging on the most abundantly flowering native plant species, where they often account for more than 90 percent of pollinators observed visiting flowers."
8) The Role of Honey Bees in Natural Areas
A recoreded video webinar with The Xerces Society and Pollinator Partnership. Non-native managed and feral honey bees negatively affect native plant communities by disrupting the co-evolved pollinator networks, and reducing seed set in native plants. They also preferentially forage on non-native plants (which they likely co-evolved with in countries of their origin) and thereby encourage invasiveness. Honey bee interference with native plant communities and their pollinators are found to therefore have compounding ecosystem effects.
9) Native Bees Increase Crop Production, Flowers Near Apiaries Carry More Bee Viruses
"One of the most important studies looked at 41 farms on six continents that grew almonds, blueberries, buckwheat, cherries, coffee, cotton, kiwi, mango, passionfruit, pumpkins, strawberries and watermelon. The results blew up the conventional wisdom. Wild insects increased fruiting in every single farm where they were present, but honeybees only produced a significant increase in fruiting 14% of the time. There wasn’t a single crop for which increased fruiting caused by honeybees outperformed that of wild bees. On average, wild bees delivered twice the bump of honeybees."
10) Focus on Native Bees, Not Honey Bees
Compelling summary by an ecologist on how native bees can engage the public's imagination -- and empathy -- even more so than honey bees, and how that will spur greater ecological awareness as we rewild urban and rural areas. Don't raise more turkeys to save birds = don't raise more honey bees to save pollinators.
11) Will Putting Honey Bees on Public Lands Threaten Native Bees?
This thorough and long piece puts into context the issues of honey bee agriculture and our dependence on them for pollination services, as well as the threats they may pose to some of our last wild places -- including threats to both native bees and plant communities.
