| Specimen Impact | Because brook trout have displaced cutthroats wherever they coexist, the brookies posed a threat to all the Yellowstone cutthroat in the lake and drainage above Yellowstone Falls. Jones notes that "the brook trout had the potential to be an ecological disaster" and not just for cutthroat. "Grizzly bears and birds (including bald eagles) use the spring cutthroat spawning run as a food source. Brook trout spawn in the fall and would have eliminated that important food supply." Jones hopes two years of rehabs have eliminated the problem, but he and other biologists are still holding their breath. |
