- Sun Creek, a headwater stream in Crater Lake National Park, contains a population of Endangered Species Act listed, native Bull Trout (Salvelinus confluentus) recovering from decades of competition with nonnative Brook Trout (S. fontinalis).
- The National Park Service (NPS) eradicated Brook Trout from upper Sun Creek during the early 2000s.
- Bull trout have gradually expanded to occupy vacant habitat in the stream, but many areas that once contained high densities of Brook Trout remain only sparsely populated by Bull Trout.
- Current management actions will eradicate nonnative trout from the lower portion of the Sun Creek watershed and create additional vacant habitat for Bull Trout.
