The Friends of Five Creeks Weed Warriors continue to eradicate two of the creek's most invasive species from the south creek: Himalayan blackberries and Algerian ivy. On this visit, they brought along a group of Japanese students who are visiting from Kyoto. The students are attending a class to learn the  English language through environmental restoration.  They are learning interesting words such as invasive species, eradication,  erosion, and urban runoff.
