2020 Cal-IPC Symposium Video Recordings

The 2020 Cal-IPC Symposium gathered more than 650 participants from California and beyond to share the latest in invasive plant management and research. Though we couldn’t meet in person, the online format gave us the opportunity to record and share these presentations for future viewing.

Each video features a full session, an hour in length, with minor editing to remove mic checks or major technical glitches. View the posters and slide shows in PDF format on the 2020 Cal-IPC Symposium page in our archive.
