UC Berkeley has cut the pipevine at Strawberry Creek
On Friday, excavation began and the California pipevine (Aristolochia californica) was cleared, the largest and most productive known breeding stand of the California pipevine swallowtail in the Bay Area, where surveys have recorded 1,000 to 2,000 caterpillars in peak months. It is the only plant this butterfly can breed on.

Students witness every stage, and help build the habitat that makes it possible.
This planting season
Where should the pipevine go?
California pipevine is the only plant the pipevine swallowtail can breed on. Tell us about a spot that would work: a creek bank, a shady fence line, a corner of your own yard. We'll plant it with volunteers this winter.
