2021 Cal-IPC Symposium Video Recordings

The 30-Year Anniversary 2021 Cal-IPC Symposium was our largest yet! More than 770 participants from California and beyond gathered to share the latest in invasive plant management and research. The online format gave us the opportunity to record and share these presentations for future viewing.

Each video features a full session or discussion/workshop, with minor editing to remove mic checks or technical glitches. Lightning Talks are at the bottom of the page. View the posters and PowerPoint presentations in PDF format on the 2021 Cal-IPC Symposium page in our archive.

 

Overview: 30 Years of Cal-IPC and Weed Management, and Session 1: Expanding the Community in Conservation

(0:20) Welcome and Overview: 30 Years of Cal-IPC and Weed Management

(23:45) Session 1, Intro – Moderator, Josie Bennett, Cal-IPC JEDI Committee Chair

(26:20) Why Justice, Equity, and Belonging Matter in Environmental Restoration Work – Shelana deSilva Policy and Advocacy Strategist, SdS Consulting

(41:02) Integrating JEDI Principles into Conservation – Amy Lethbridge Chief of Staff, Mountains Recreation and Conservation Authority, Community Nature Connection, National Association for Interpretation

(59:30) Panel Discussion

 

Workshop on the What & Why of Diversity, Equity, Inclusion, and Justice (DEIJ)

We define basic terms like justice, equity, diversity, inclusion, and cultural competency, and then lay out all of the reasons why this work is important to organizations, agencies, foundations, and institutions operating in plant conservation. This webinar will help you articulate what you mean when you are talking about JEDI and why it is important to your organization’s mission.
Led by the Avarna Group.

 

Workshop on the History of Conservation and Social Justice

We juxtapose better known conservation history with social history to draw connections between the history of land conservation and the continued marginalization and exclusion of Black, Indigenous, and people of color. In particular, we examine concepts of settler colonialism and how other conservation organizations have engaged in the concept of “decolonization.”

Led by Aparna Rajagopal-Durbin, Avarna Group
