Completing the loop: Combining occupancy modeling, crowd-sourcing, and eDNA sampling to inventory bull trout across their U.S. range Interest in using environmental DNA (eDNA) sampling to monitor aquatic species is exploding. This technique makes it possible to conduct rapid and cost-effective broad-scale species assessment and monitoring, particularly when informed by robust species distribution models. Here, we provide preliminary results from an effort to identify habitats occupied by juvenile bull trout in all 4th-code basins constituting their historical U.S. range.We developed a sampling template based on 1) the probability of habitat occupancy by juvenile bull trout from the Climate Shield model and 2) simulated and empirically tested probabilities of eDNA-based detection of stream-dwelling salmonids. A cadre of state, tribal, federal,...

Resource managers are charged with maintaining bull trout across their range, but monitoring this species is difficult and many populations have rarely or never been sampled. To reduce this uncertainty (and regulatory gridlock), we propose to coordinate a crowd-sourced field assessment of the distribution of bull trout in the U.S. by using inexpensive, reliable environmental DNA (eDNA) sampling. Samples collected by this multi-partner effort can be used to evaluate many other species (e.g., a biodiversity assessment) with no additional field costs and can serve as a...

Web Site, completed, environment, Fewer tags A range -wide, eDNA -based survey of the U.S. distribution of juvenile bull trout The bull trout is an ESA-listed species with a historical range that encompasses many waters across the northwestern U.S. Though once abundant, bull trout have declined in many locations from an array of factors —habitat degradation, population isolation, and nonnative species invasions (USFWS 2014)— and there is recent evidence of range contraction in response to climate change (Eby et al. 2014). Federal listing mandates that agencies have reliable and precise information about the distribution of bull trout in thousands of streams, but bull trout surveys are expensive because the fish are often rare and difficult to collect (USFWS 2008). Consequently, many potentially or historically occupied habitats have been...

Tribes, completed, environment, Fewer tags eDNA Climate Shield Model Populations of many cold-water species are likely to decline this century with global warming, but declines will vary spatially and some populations will persist even under extreme climate change scenarios. Especially cold habitats could provide important refugia from both future environmental change and invasions by non-native species that prefer warmer waters. The Climate Shield website hosts geospatial data and related information that describes specific locations of cold-water refuge streams for native Cutthroat Trout and Bull Trout across the American West. Forecasts about the locations of refugia could enable the protection of key watersheds, be used to rally support among multiple stakeholders, and provide...
