    This presentation explores toxic plants (and beyond!) that are commonly around in our gardens and natural landscapes in San Diego County.

    Learn how to recognize harmful species, understand

    their effects on the human body, and gain practical tips for staying safe while enjoying the outdoors. Perfect for gardeners, hikers, and nature lovers alike, this talk blends botanical insight with real-world medical perspective.

    Dr. Megan Tresenriter is a board-certified Emergency Medicine physician with nearly a decade of experience treating everything from heart attacks to rattlesnake bites—sometimes all in one shift. In addition to her medical expertise, Megan is a dedicated gardener and plant enthusiast and has developed a deep appreciation for the botanical world—both its beauty and its dangers.
