MIM and Adaptive Management

PURPOSE of ADAPTIVE MANAGEMENT: To achieve long-term desired conditions

“Emphasis should be placed on long-term monitoring of trend to determine whether resource management objectives are being met or not” (U of I Stubble Height Review Team)

What is adaptive management?

“Adaptive management is an interdisciplinary planning and implementation process that identifies desired riparian conditions, defines criteria for modifying grazing operations when progress towards achieving the desired conditions is not being made, and specifically defines the monitoring strategy and protocols.”

In other words: "...learning to manage by managing to learn...“

(Bormann, B.T., P.G. Cunningham, M.H. Brookes, V.W. Manning, and M.W. Collopy. 1993. Adaptive ecosystem management in the Pacific Northwest. USDA For. Serv. Gen. Tech. Rep. PNW-GTR-341. 22 pages.)

Benefits of Adaptive Management

Recognizes uncertainty and uses monitoring to determine whether mitigation measures are cost effective and if predicted impacts occurred.

Cost of mitigation measures can be reduced or redirected if a mitigation measure either far exceeds what is necessary to protect the resource or fails to achieve the desired outcome.

Helps address incomplete or unavailable information.

The Adaptive Management Cycle

Decision Tree Provides a logical management process for

evaluating annual grazing impacts

Implementing Annual Grazing Adaptive Management

1. Was the Annual Indicator standard achieved? (Stubble height, etc.)

4. Review current vs. desired condition and trend. Need for adaptive mgmt change?

5. Assign adaptive action. Was the action implemented?

6. Is failure the result of a design problem or changed condition outside the control of permittee?

7. Is an administrative action warranted?8. Implement

Administrative action

2. Continue current management and monitoring (short- & long-term) to determine if desired condition is being achieved.

3. Change or modify annual indicator and/or management as appropriate.

The Decision Tree Process Recognizes that grazing management to achieve long-term

desired conditions is often experimental, requiring an adaptive management approach.

Requires managers to analyze the effect of grazing on the achievement of resource conditions

Prevents managers from initiating immediate adverse actions when an annual indicator is exceeded

Provides for management flexibility since “annual indicator

standards” are modified at any time to ensure that they are working

Adaptive Management Actions- are applied when

Monitoring shows management objectives have not been achieved or that trend towards achieving desired conditions is not improving

Annual indicators of grazing use or grazing standards are not met.

Climatic events, fire, flood or uses and activities detrimentally impact resource conditions and a modification of grazing use is needed to provide for recovery of the site.

Performance measures or impact thresholds that would signal that management adjustments are needed

Decision Tree – annual indicator standards

Trend on long-term indicators – any negative trend would signal a management adjustment

Elk Creek Scenario 2005 End-of-season stubble height was 5.6”

(CAUT) and the annual indicator standard is 6”, but streambank alteration was measured at 39% with an annual indicator standard of 20% (Block 1). This level of use has occurred for several years.

1. Was the Annual Indicator standard achieved? (Stubble height, etc.)

No for streambank alteration

4. Review current vs. desired condition and trend. Need for adaptive mgt change?

Elk Creek Scenario

Current Condition • Mid-seral ecological status• Low bank stability and cover• High stream width, moderately low proportion of hydric stabilizers on the streambanks

4. Review current vs. desired condition and trend. Need for adaptive mgmt change?

Yes (Cause: livestock in pasture too long, Significant: Yes since result is failure to meet desired conditions)

Desired Condition• Late-seral ecological status• High bank stability and cover• Low stream width, high proportion of hydric stabilizers on the streambanks

2005Stubble Height = 5.6”Streambank Alt. = 39%

Woody Use = 50%Streambank Stability =

35% (low)Streambank Cover = 64%

Elk Creek Scenario

Yes

5. Assign adaptive action. Was the action implemented?

• Adaptive action is implemented to use 20% streambank alteration as the trigger to move livestock from the pasture (stubble height trigger of 6” is not moving site towards desired conditions). 20% streambank alteration may result in an 8 or 10” stubble height which may be used also if it correlates to SBA.

Elk Creek Scenario

Next years (2006) annual use authorization adds streambank alteration of 20% as an annual indicator standard to be used as a trigger and changes stubble height to 8 or 10” and process repeats.

If stubble height and SBA is presented in authorization documents as Annual Indicator standards, no problem…

If presented as a rigid numeric standard, administrative modifications are required.

5. Assign adaptive action. Was the action implemented?

1. Was the Annual Indicator standard achieved? (Stubble height, etc.)

Yes

Not making much progress: the policy “Field managers will make reasonable

efforts to assist applicants to propose livestock grazing management in their application that will meet the ISRH or begin to make significant progress toward meeting the standards.” (BLM – Idaho Standards for Rangeland Health)

Manager decides to follow the ID Team recommendation

“Change period of use in the riparian pasture, June 1 to June 15”

Conclusions Adaptive Management is a PROCESS

Use the Decision Tree to describe the PROCESS

Monitoring is required to implement it

Some adaptive management actions may require site-specific NEPA (range improvements)

Every situation is unique

Paradigm shift – prescriptive to goal-oriented management
