Surveillance entails regular surveys to detect new infestations of species not known to be present in a region. The strategic potential depends on the proximity of nearby infestations and the suitability of the area. Listed here are species occurring within 50 miles of the selected region.
Eradication entails complete removal of all infestations in the area. These opportunities result from small, isolated infestations. The strategic importance of an eradication opportunity can be further assessed based on the degree of isolation as well as the suitability of the surrounding area. Determining the feasibility of eradication requires surveying infestations in the field.
Containment entails limiting the spread from existing infestations. These opportunities result from larger groups of infested quads. The strategic importance of a containment opportunity can be further assessed based on how distinct the boundaries of the infestation are, how isolated it is, and the suitability of the surrounding area. Determining the feasibility of containment requires surveying infestations in the field.
Managed plant species are the focus of some level of active management in the region. Management may not address all quads that are infested with the plant in the region. Within any given quad, management may not address all populations of the plant. Management in a quad may result in stabilizing or reducing the overall abundance of the plant, or the plant may still be spreading overall.

The Cal-IPC Inventory categorizes plants as High, Moderate, or Limited, reflecting the level of each species' cumulative impacts statewide in California. Two additional categories are "Alert" and "Watch." An Alert is listed on species with High or Moderate impacts that have limited distribution in California, but may have the potential to spread much further. Species on the "watch" list have been assessed as posing a high risk of becoming invasive in the future in California. More info
CDFA's rating of A, B, C, D, or Q reflects CDFA's view of the statewide importance of the pest, the likelihood that eradication or control efforts would be successful, and the present distribution of the pest within the state. More info
For some species at Cal-IPC, climate change modeling was done to predict the species' suitable range due to climate change.
Expert knowledge on over 130 species was collected at the 2011 Cal-IPC Symposium.
