Discover how adding late-season flowering plants to urban gardens can support both managed and wild bee populations. This article explores the latest research on the impacts of honey bee apiaries and urban development on diverse bee communities. Learn about the specific bee genera most affected and how you can help create thriving bee-friendly habitats. Pollinators play a vital role in our ecosystems, and this post offers practical tips to nurture a healthy, diverse bee population in your local community.

Unraveling the Interplay Between Honey Bees and Wild Bees
The U.S. is home to nearly 4,000 native bee species, each playing a critical role in pollinating agricultural, urban, and natural landscapes. While honey bees are not native to the country, their managed populations have raised concerns about potential competition with wild bees for resources and the spread of pathogens.
According to a recent study published in the journal Science of The Total Environment, the presence of honey bee apiaries and urban development can have a negative impact on the abundance of certain wild bee genera. The researchers found that six out of the 33 genera studied, including long-horned bees, green bees, and sweat bees, were particularly affected by these factors.
The study’s lead author, Gabriela Quinlan, explains that ground-nesting bees and those that forage later in the season tend to be more vulnerable to the challenges posed by urban environments and high concentrations of honey bee colonies. These bees may struggle to find suitable nesting sites and floral resources within their limited flight range.
Diversifying the Urban Landscape for Bee Conservation
To help alleviate the stressors on these at-risk bee genera, the researchers suggest planting late-season flowering plants and leaving bare ground for nesting resources in urban gardens and landscapes.
“Native flowering trees and shrubs in particular provide a bonanza of resources for bees,” says Christina Grozinger, Publius Vergilius Maro Professor of Entomology and director of the Center for Pollinator Research at Penn State.
Beekeepers can also play a role in supporting wild bee populations by managing pests and diseases within their honey bee colonies, which can reduce the potential for honey bees to spread diseases to their wild counterparts.
The study highlights the interconnectedness of different bee species and the importance of considering them as part of a broader community, rather than as individual entities. By understanding the specific needs and vulnerabilities of various bee genera, we can develop more targeted conservation strategies to support the overall health and diversity of urban bee populations.
Harnessing Technology to Monitor Bee Communities
One of the key challenges in studying the impacts of honey bees and urban development on wild bees is the lack of comprehensive data on population sizes of most wild bee species across the United States.
To address this, the researchers are working on developing new monitoring systems that can track bee populations in a non-lethal and automated way. The INSECT NET graduate training program at Penn State is aiming to create these innovative tools, which will greatly enhance our understanding of how different bee communities respond to various environmental factors.
In the meantime, the researchers encourage people to use Penn State’s Beescape decision-support tool to learn more about the resources available to bees in their local area, as well as the risks posed by pesticide use and weather conditions. By empowering individuals to take action in their own communities, we can collectively work towards a future where both managed and wild bees thrive in our urban landscapes.
