Pesticides & Herbicides

Pesticides and herbicides can be a threat to creeks if allowed into the storm drainage system.

  • Pesticides kill aquatic insects that are important to creek ecosystems.
  • Herbicides harm beneficial plant life that form the base of the aquatic food web.

What UC Berkeley is doing?
