The Science Behind Pollinator Gardening Virtual Class with Matthew Shepherd


We all want our gardens to make a difference for pollinators, but what does the science actually say about how to help? In this webinar, we move beyond general gardening advice to explore the research that informs best practices for supporting bees, butterflies, and other beneficial insects right in your own backyard.

Drawing on peer-reviewed studies from researchers across North America and Europe, we will look at why native plants outperform non-natives for insects, how something as simple as leaving the leaves can shift insect populations, what the data shows about the real impacts of pesticides (including those lurking in plants purchased at your local garden center), and how much bee diversity a well-managed garden can actually support. We will also dig into recent findings on butterfly populations in the United States, including the landmark Xerces Society State of the Butterflies report and the research published in the journal Science on which it is based.

This is not a lecture of charts and tables. It is a conversation grounded in evidence, designed to help you garden with confidence and purpose.
