Addressing Invasive Plant Species in California
Executive Director Doug Johnson of Cal-IPC discusses the challenge of 200 invasive plant species across California's vast land, requiring spatial prioritization for eradication and containment. The solution involves aggregating digital datasets, collecting expert knowledge, assessing priorities based on distribution, and using range modeling to predict spread. Funding sources and strategies for utilizing phone apps, email alerts, prioritization, management tracking, and more are also outlined.
