The Middle and North Forks of the John Day River are within the known extent of spawning, rearing, and adult holding habitats of ESA threatened bull trout, yet little is known regarding their abundance, distribution, or population trends. The absence of these data precludes the ability of managing agencies to prioritize restoration or management actions as they relate to bull trout, or to evaluate recovery metrics. To bridge this knowledge gap we are conducting a suite of monitoring actions including spawning surveys, eDNA sampling, occupancy modeling, and snorkel sampling.
