Paper by McHugh et al. (2017) shows how life cycle models can be used to assess restoration alternatives

Pete McHugh and Carl Saunders led this effort in the Middle Fork John Day to demonstrate how site scale NREI models (e.g. Wall et al, 2016) to inform network scale models to produce fish population capacity estimates that can drive life cycle models. They then use this approach to produce realistic restoration scenarios to see what sort of capacity increases might be produced by various restoration alternatives and what (if any) population level impact this may have. This framework and vision was laid out conceptually in Wheaton et al. (2017), and this case study application and the online supplement provide many of the methodological details for how to pull it together. The McHugh et al. (2017) paper was just published in Ecological Modelling.
