A Watershed-Scale Monitoring Protocol for Bull Trout

Bull trout are a charr species native to streams of the Pacific Northwest that require extremely cold stream temperatures and relatively pristine habitat conditions to persist. Population declines during the 20th century prompted listing under the Endangered Species Act and several national forests have also designated bull trout as a Management Indicator Species. Such designations require monitoring the status and trends of populations across extensive tracts of US Forest Service lands, but limited budgets often make this a daunting task. Researchers at the Boise Aquatic Sciences Laboratory have developed a watershed-scale monitoring protocol for bull trout designed to address these needs. Rather than relying on intensive and costly monitoring of abundance at a few sites, the protocol focuses on temporal patterns of occurrence within suitable habitat patches, thereby requiring less intense sampling at individual sites and making it possible to sample larger areas more relevant to land managers. As initial data are collected, models of detection efficiency and species occurrence can be developed and used to refine future sampling efforts based on desired levels of statistical certainty and habitat conditions.
