Prisoners used to be put to work on chain gangs. Now they do science. Nalini Nadkarni, a forest ecologist at Evergreen State College, recruited inmates from her local prison, the Cedar Creek Corrections Center in Littlerock, Washington, to conduct experiments on how to cultivate mosses in mid-2004. Their results are the first step toward the commercial cultivation of mosses, a green alternative to the current practice of collecting it from the forest floor. The U.S. floral industry alone consumed up to 81 million dry pounds of moss in 2004, a grossly unsustainable figure.
The collaboration was a natural fit. Nadkarni had know-how to share but was too busy to watch mosses grow; the inmates were starved for stimulation and had time to spare. “I picked the four most common types of mosses, and we set up some really basic experiments,” she recounts. “Which species grew fastest? How should we water ...
