A particular emphasis on Uncertainty &Learning (as an objective)
Adaptive management identifies uncertainties, and then establishes methodologies to test hypotheses concerning those uncertainties. It uses management as a tool not only to change the system, but as a tool to learn about the system.
This approach is very different from a typical management approach of 'informed trial-and-error' which uses the best available knowledge to generate a risk-averse, 'best guess' management strategy, which is then changed as new information modifies the 'best guess'.
The achievement of these objectives requires an open management process which seeks to include past, present and future stakeholders. Adaptive management needs to at least maintain political openness, but usually it needs to create it. Consequently, adaptive management must be a social as well as scientific process. It must focus on the development of new institutions and institutional strategies just as much as it must focus upon scientific hypotheses and experimental frameworks. Adaptive management attempts to use a scientific approach, accompanied by collegial hypotheses testing to build understanding, but this process also aims to enhance institutional flexibility and encourage the formation of the new institutions that are required to use this understanding on a day-to-day basis.

(a) Expand the GOALSWe use rivers for many things … engage all interested parties in a structured, constructive conversation
(b) Refine the GOALS: What, specifically, do people want?Geometry? Structure? Function? Appearance? Ecosystem services?
(c) Learn from projectsData must be collected, standardized, archived, and accessed … even thenTo learn, we need clear, testable methods and design hypotheses

DECISION STEPSDECISION FRAMEWORK
Goals describe a general condition or outcome. Goals express what people want. No goal is intrinsically wrong. Some goals are unclear, ineffective, or inappropriate. A goal should be sufficiently clear that(1) possible actions to achieve the goals can be clearly defined(2) appropriateness of reach‐scale actions to achieve the goals can be effectively evaluated(3) success can be defined
Assessment is the essential link between GOALS and PROJECT OBJECTIVES. You ask two essential questions:(1) Can this goal be achieved at this site, under present and future watershed conditions?(2) Can this goal be better achieved with actions other than stream restoration?
In assessing stream restoration goals, establish a cause‐and‐effect link between the site and its watershed, ecosystem, and social context. Understanding the history of the site and its watershed is key ‐ you will not be able to forecast restoration outcomes without the spatial and temporal context that explains how conditions came to be the way they are now.
Stream restoration project objectives are ultimately defined at the project scale. Think of them as an excellent, focused set of instructions that a stream design professional can use to develop design alternatives. These objectives should be appropriate (defined at the reach scale)relevant (achieving the objective correlates to achieving the associated goal)feasible (capable of being achieved)measurable (support definition of metrics that that demonstrate progress toward project objectives)
Given appropriate, relevant, feasible, and measurable objectives, develop metrics that demonstrate progress toward objectives

2 What problems and opportunities might be addressed by a stream project? What do people want? What physical, legal, financial, or regulatory constraints influence what is possible? EVALUATE CONTEXT
3 Identify key assessment questions and the watershed, ecosystem, and social information needed to address them. What is the physical, ecological, and social history of the watershed?
4 Is it feasible to address problems and opportunities at this site under present and future watershed conditions? Is a stream project the best way to address problems and opportunities?PROJECT OBJECTIVES
5 Select appropriate local objectives that address problems, opportunities, and constraints
6 Define metrics (measurable system properties ) that demonstrate progress toward project objectives

Appropriate project objectives and metrics enable a predictive approach to design
Potential risks and benefits – and their uncertainty – determine the appropriate level of effort.
Develop a range of restoration actions that may achieve local objectivesestimate the range of objective performance for different costsestimate uncertainty in objective performance
Always evaluate do‐nothing and passive restoration alternatives
Multi‐criteria decision analysis provides a robust, transparent basis for evaluating alternatives. It will not solve the design problem, but with effective supporting science, it provides the most favorable basis for evaluating tradeoffs and making good decisions.
Watershed, ecosystem, and social factors define the boundary conditions and constraints used to design restoration actions. These include the supply of water, sediment, nutrients, and organisms to the project reach, food webs and life histories of key organisms, and the social interests, pressures, and regulations that can define or constrain actions.

Develop alternatives
Evaluate tradeoffs
Package actions into project alternatives. Alternatives are judged independently in their ability to achieve objectives.
Performance levels and objective weights are used to evaluate alternatives. MCDA allows alternatives to be evaluated in a transparent and flexible manner. Value of additional research to reduce uncertainty can be evaluated. Poorly defined objectives are exposed.

Act & Learn LoopExplanation
If the action did not produce desired result, predictive design provides a basis for making corrections.
How do you do that with an approach based on narrative, or untestable hypotheses, or vague assertions that the project will make things better?
The key elements for learning:appropriate project objectives and metrics, allowingpredictive design, which leads tohypothesis‐based monitoring, the data for which must be botharchived, and analyzed

To the CAP and to the site:
Let’s get started on ALO: Appropriate Local ObjectivesPM: Performance MeasuresAP: Alternative Packages
To protect the Logan River from degradation and the growing threats of floodplain development, a Conservation Action Plan (CAP) has been developed for the portions of the Logan River from First Dam (at the mouth of Logan Canyon) through Cache Valley to the confluence with the Little Bear River at Cutler Reservoir (Figure 1). The development of a short‐ and long‐range vision for the river is needed to coordinate and prioritize conservation efforts and ensure a sustainable river system for future generations. Stakeholder groups representing residential, commercial, recreational, and agricultural interests have participated in the development of this CAP. The CAP is a dynamic set of objectives that can be revised as needed when new threats or conservation solutions are identified.
