Invasive Plant Inventory - 2017 Update

Cal-IPC is undertaking a periodic update of its California Invasive Plant Inventory. All stakeholders are encouraged to comment on the process. The initial 60-day public comment period is March 8 through May 8. The project team will post responses to comments received, and a second public comment period will be held for any plant species whose categorization changes based on input received during the first comment period.

The update comprises two proposed additions. First, addition of 10 plant species based on assessment of current impact, invasiveness and distribution using the Plant Assessment Form (PAF) protocol established by Cal-IPC and partners in 2003. Second, addition of 87 plant species as "high-risk potential invasives" based on the predictive assessment protocol developed by UC Davis and the University of Washington.

View PAFs for 10 plant species proposed for addition based on current impacts in California.

View predictive assessments for 87 plant species proposed for addition based on risk of becoming invasive in California.

Submit comments to project lead Ramona Robison by May 8.

See list of proposed additions.

The project team will review all comments and make adjustments as appropriate. Any significant changes (such as recategorization of a plant) will then be released for a subsequent public review period of 30 days, after which the revised Inventory will be finalized.
