Dear Ginger, sumac bran is not a species of sumac (genus Rhus). Sumac bran is a kind of Sorghum, which is a grass. Sumac bran is a special, high-tannin content sorghum. As such, without proper processing (soaking, sprouting, fermenting), it would actually pose real antinutrition properties because the tannins would bind to minerals in your GI tract and prevent their absorption. What the road crew mowed down was a different species of plant than you are researching for antioxidant content. I hope this helps.
