The attached link is an article written by Kevin Jernigan, Olga S. Belichenko, Valeria B. Kolosova and Darlene J. Orr that compares uses of plants including berries from the past through elder recollections compared to present uses. They also compared usage with communities in Nome and Kotzebue. Edible plant use has dropped overall from previous years (13%) but the awareness of medicinal uses has skyrocketed (+225%) no doubt because of the interest in antioxidants and other bioactive components. I completed a similar project in the mid 1990s in Ft. Yukon, Alaska and found about a 20% drop in native plant uses, but my project was before all the interest in antioxidants.
Some of the plants whose use had actually increased include: wild chives (Allium schoenoprasum), tilsey sage (Artemisia tilesii), crowberry (Empetrum nigrum), blueberry (Vaccinium uliginosum), lingonberry (Vaccinium vitis-idaea), river beauty (Epilobium (Camerion) latifolium, mountain sorrel (Oxyria digyna), sour dock, (Rumex arcticus), and cloudberry (Rubus chamaemorus). The plant locally called stinkweed or tilsey sage is interesting because I found it mentioned in nearly every ethnobotanical reference written in Alaska. It has extensive medicinal uses throughout the state and now the Russian Far East. All the berries mentioned are also the most popular berries harvested in northern Alaska. The berry with the greatest increase in uses from the past is mesutaq better known as masru, lingonberry or low bush cranberry. No surprise there!
