Summer—it’s a time for swimming, BBQs, camping, and eating invasive species.

Last week during California Invasive Species Action Week (June 2 – June 10), we highlighted several pests, but there are many more invasive species out there. Now that you know about them, share your knowledge of invasive species with others. And no matter what your summer plans, here are some things YOU can do about invasive species from the California Department of Fish and Wildlife and California Department of Food and Agriculture.

If you've got a great recipe for wild fennel, the website Eat the Invaders wants to know. Wild fennel is listed as moderately invasive by the California Invasive Plant Council (CAL-IPC). It came from southern Europe and the Mediterranean where it is used as a spice. (Photo: Joseph M. DiTomaso, UC Davis Dept. of Plant Sciences)

If you've got a great recipe for invasive brown garden snail, the website Eat the Inbaders wants to know. Don't bring snails and other animals into California for food! That's how the brown garden snail ended up here in the 1850's. (Photo: Jack Kelly Clark, UC IPM)
