Most Common Invasive Plants

Think you have an invasive plant or noxious weed?

Explore this section to learn about some of the most common and/or problematic species in Santa Barbara County. We include both the scientific name and the common name. Some species have no common name and some have several. Keep in mind, there are over 700 non-native plant species that occur in wildlands in Santa Barbara County; so not all of them are listed here. Many of these species have multiple “look alikes” that are not invasive or harmful. There are over 2000 native species in Santa Barbara County.

If you are unsure about the identity of a plant, check with a botanical expert before you spend time and resources to remove it.
