Scenarios

The R2R structured decision making process includes 3 rounds of modeled scenarios.

Scenarios are implemented in the modeling process via the R2Rscenarios package, which has further documentation, and also allows users to create and build custom scenarios.

Round

1

Scenario type

Bookend

Focal question addressed

How do salmon biological recovery objectives respond to intensive management actions in each of four categories (habitat, hydrology, hatcheries, and harvest)? Bookend scenarios evaluate a single, intensive management action with the goal of learning how the modeled system responds to different management options.

Round

2

Scenario type

Blended

Focal question addressed

How can salmon recovery be achieved through different combinations of management actions? Blended scenarios build on findings of the bookend scenarios to explore multiple, distinct approaches to meet salmon recovery criteria of biological objectives.

Round

3

Scenario type

Balanced

Focal question addressed

How can scenarios be modified to achieve salmon recovery while balancing other socioeconomic interests in the Central Valley? Balanced scenarios build on findings of the blended scenarios to explore combinations of actions that meet biological recovery criteria while better satisfying other socioeconomic interests.
