Versions 2.0.3 and 2.1.3 are updates of versions 2.0.2 and 2.1.2, which are described below.

It was examined as a example successful ecological management model in this review: Will et al.

Modeling potential river management conflicts between frogs and salmonids. Our first publication using FYFAM describes its first version and applies the model to the question of how river management to enhance salmonid populations could affect frog breeding success. The time step is determined by the flow and temperature input: daily input produces one-day time steps hourly input would produce one-hour time steps or the user can insert short-term events such as sub-daily recreational flow pulses into a daily simulation. To date we have modeled sites using 1-meter and 1-foot resolution. The model is driven by two-dimensional hydrodynamic modeling (done separately using any hydrodynamic model) mapped onto a square grid space, with a user-chosen spatial resolution (grid cell size). FYFAM can predict how changes in flow and temperature, from sub-hourly to seasonal scales, can affect the success and timing of frog breeding, incubation, and tadpole development. In much of California's breeding habitat, flows and temperatures are controlled by upstream reservoirs and potentially also affected by land and water management actions. Our Foothill Yellow-legged Frog Assessment Model (FYFAM) is designed as a tool for evaluating and comparing flow and temperature regimes for their effect on frog breeding success. Therefore, breeding success depends very much on flow and temperature regimes. Lower temperatures increase the time it takes eggs and tadpoles to develop. Tadpoles are also subject to being either stranded or washed away by sudden changes in flow. In spring, adult breeders place eggs along channel margins in habitat that, for eggs to survive and hatch into tadpoles, must neither be dried out as flows decrease after the rainy season ends nor be washed away by late-season flow events. The foothill yellow-legged frog ( Rana boylii) is unique and important because it breeds in rivers and streams, not still water.
