Fabulous Filtering Fungi

Kwiaht Center for the Historical Ecology of the Salish Sea, WA


At a high school in the San Juan Islands, WA, high school students were challenged with the issue of addressing motor oil on roadways that was coming from increased eco tourism. The motor oil was washing off roadways and into the bay and was affecting keystone species, such as herring, in the Puget Sound. In response, the students worked with the Kwiaht Center for the Historical Ecology of the Salish Sea to identify, collect and analyze the oil absorbency of various local mushroom species. Then they inoculated straw bales and wood chips with the most effective mushrooms to create a filtering barrier between the road and the ocean. Download Teacher Guide here.
