Register now! 2025 Cal-IPC Symposium – Ventura and Online, Nov. 12-15.
Join us for another dynamic gathering of California land mangers to network, learn, and celebrate our hard work.
Once again, we’re going hybrid! Join us streaming online, or book your rooms now at the Ventura Beach Marriott, a small town oasis two blocks from San Buenaventura State Beach and minutes from downtown. Registration and room blocks are available to book now!
Theme sessions will explore land stewardship approaches that go beyond invasive plant removal by promoting ecological resistance to invasion, resilience to changing conditions, and recovery from major events like wildfire. Sessions will highlight strategies for strengthening habitat health while also addressing the human dimensions of adaptability in conservation.
