Adaptation and Mitigation = Synergistic

Mitigation Adaptation

Sequester Carbon in Trees, Forests, and Products

Conserve Carbon Stocks Strengthen Adaptability of Forest-Dependent Communities

Create Better-Adapted Forests

Mitigation

Modified from FAO 2010

Adaptation and Mitigation Defined ADAPTATION • Adjustment of human or natural systems in response to

climate change – Position forests to become more healthy, resistant, &

resilient – Facilitate ecosystem responses to climate change

when appropriate MITIGATION • Human activities to reduce the effects of climate change

by reducing sources and enhancing sinks of greenhouse gases

What actions can be taken to enhance the ability of a system to

cope with change and

meet goals and objectives?

Climate-Driven Changes

Uncertainty and Risk

Design actions that are robust across a range of potential future conditions

Option #1 – Resistance Improve the defenses of the forest against anticipated changes or directly defend the forest against disturbance in order to maintain relatively unchanged conditions

• Short-term • High-value

?

Option #2 – Resilience Accommodate some degree of change, but encourage a return to a prior condition after disturbance

Swanston and Janowiak 2012: www.treesearch.fs.fed.us/pubs/40543, Janowiak et al. 2014

1. DEFINE area of interest, management objectives, and time

frames.

2. ASSESS climate change impacts and

vulnerabilities for the area of interest.

3. EVALUATE management

objectives given projected impacts and

vulnerabilities.

4. IDENTIFY and implement adaptation

approaches and tactics .

5. MONITOR and evaluate effectiveness

of implemented actions.

Activity #2

CSIRO (B1) CSIRO (A1B) HAD (A1B) MIROC (A1B) MIROC (A2)

In this activity you will use your silvicultural expertise to illustrate how climate change and uncertainty may affect stand-level management for specific ecosystems or forest types

Activity #2

As a group, select a forest type or ecosystem to work in 1) Create and describe a hypothetical management situation

– Conditions: Location, site conditions, species composition, stand structure, disturbance history and susceptibility, etc.

– Typical management: Management goals and objectives, common practices

Activity #2

As a group, select a forest type or ecosystem to work in

2) Identify important climate change considerations – Anticipated effects on various

forest components – Characteristics that

increase/reduce vulnerability

3) Identify challenges or opportunities for meeting management goals under climate change

Activity #2

What actions can be taken to enhance the ability of the area to adapt to anticipated changes and meet

management goals?

Where are you working and what are your forest management goals?

Forest:

Location and conditions:

Current management:

What climate change impacts create challenges or opportunities for meeting these goals?

What actions would you recommend to enhance the ability of forests to adapt?

Identifying Adaptation Tactics 1. DEFINE area of

interest, management objectives, and time

frames.

2. ASSESS climate change impacts and

vulnerabilities for the area of interest.

3. EVALUATE management objectives given projected impacts

and vulnerabilities.

4. IDENTIFY and implement adaptation

approaches and tactics.

5. MONITOR and evaluate effectiveness

of implemented actions.
