graph of the differences in two model scenarios

Figure 1. Hypothetical graphical output describing population dynamics for the baseline condition (black bold line, with 95% confidence intervals as dashed lines) and in the face of an alternative scenario such as a management action. In this case, the uncertainty associated with the parameter estimates of the baseline condition overwhelms any ability to confidently discern an appreciable impact of the management action except as it may occur in the 15–30 years after the action; before and after that window of time an effect is not appreciably different from the baseline condition.
