From the article:

As part of an overall mission to increase research and development of healthy and healthful food systems, the BOSF conducts studies and outreach on the benefits of foraging. Their aim is to change attitudes and policies, and to make it easier for city folk to gather food from the “wild.” The BOSF measures the nutritional content of foraged greens, tests collected produce for consumer safety — vis-a-vis environmental contamination and pollution — and sponsors the Wild/Feral Food Week, happening for the fifth year, May 24-31.

“There are a lot of reasons to forage whether you’re a city dweller or not,” said Philip Stark, associate dean of math and physical science and a professor of statistics at Cal. Stark is a principal investigator with the BOSF, the prime mover behind Wild/Feral Food Week and forager extraordinaire.
