Research Interests

As a community ecologist I am broadly interested in investigating how humans impact the environment and exploring ways we can mitigate those impacts. However, when we interact with the environment it can also have an impact on us by changing our behaviors, how we think, and how we identify ourselves. The main tools I use to explore these interactions are beneficial organisms, particularly pollinators, in agricultural settings.

My dissertation research focused on evaluating the effectiveness of planting pollinator habitat on NCDA&CS Experimental Agricultural Research Stations across the state as a conservation method to support native bee populations. The results from this work provides the most detailed survey of native bees in NC to date. In addition, I evaluated the potential of this habitat to instigate the spread of pathogens between bee species and measured the effect of the habitat's presence on nearby crop quality and quantity.

Currently, in my postdoctoral research, I am investigating the complex interactions between protecting beneficial insects and managing crop pests with the overall goal being to protect environmental health in agroecosystems. I am working to develop Integrated Pest and Pollinator Management (IPPM) recommendations for berry growers affected by the invasive fruit fly pest, spotted wing drosophila (SWD; Drosophila suzukii). To do this, I work closely with blackberry growers across NC to better understand their management decision making processes and provide real-time updates on data we collect in their fields. Together with project collaborators from 10+ different states across the US, we aim to make the management of SWD more sustainable.

Our world is very connected and actions people make in one area can affect the lives of everyone. Thus, I value working on larger geographic scales, especially internationally. Previously I worked as a field assistant in The Bahamas on a project evaluating how patch reef quality and predator presence affect fish communities as a way to explore the impacts of reef degradation and overfishing. I also have designed and led an independent research project with Peace Corps Volunteers measuring disease occurrence in managed honey bee colonies in northern rural Peru and evaluated the potential spread of those diseases to wild and native bees. In the future, I hope to continue to build international connections and collaborations.

Planted pollinator habitat in agroecosystems: How does the pollinator community respond?

Hannah K. Levenson and David R. Tarpy

Frontiers: Ecology and Evolution, 2023,

In response to pollinator declines, conservation methods such as augmented pollinator habitat are becoming popular tools to combat pollinator losses. However, further research on how this will impact bee communities in real-world settings is needed. Here, we use a 2016 initiative mandating the planting of pollinator habitat on research stations across North Carolina as an outdoor laboratory. From 2016 to 2018, we found significant increases in bee abundance and diversity. However, these increases depended on the quality of habitat, with areas of higher flower cover and diversity supporting larger, more diverse bee communities. Although we found the need for regular upkeep and maintenance of pollinator habitat in order to appropriately support bee communities. It is likely that planting pollinator habitat will not be a one-size-fits-all conservation solution, as bee species can respond differently to some habitat characteristics.

Selected Events


Bee Identification Workshop

Co-created with Assistant Professor, Elsa Youngsteadt, this workshop is a day long course designed to introduce participants to bee identification. Participants receive our identification guide, a workbook, hands on training, and field experience.

North Carolina Pollinator Conservation Alliance

The NCPCA is a partnership of 20+ organizations all focused on supporting the health and diversity of NC's pollinators through protection, restoration, and creation of pollinator habitat. As a founding member, Hannah has participated in outreach and research development.

National Honey Bee Veterinary Consortium Conference

Hannah has given over 20 academic presentations including several invited talks, like the one pictured here. She was invited to give a training presentation at the first ever National Honey Bee Veterinary Consortium which was created by professors at NC State.
