approach adapt cap framework
Approach: Adapt CAP framework
  • Selecting conservation targets
  • Defining attributes & indicators of viability
  • How will current threats be altered by CC?
  • What novel threats will arise due to CC?
  • What strategies can address current and novel threats?
think about connectivity
Targets and Conservation Area

Where is the species or ecosystem in relation to its distribution?

Think about connectivity
  • What environmental gradients affect it?
  • b. How well connected is suitable habitat across the landscape?
  • c. How does the degree of connectivity compare to the dispersal capabilities of the targets?
consider existing and novel threats
KEAs and ThreatsConsider existing and novel threats
  • How will novel CC threats affect each ecological attribute of the species or ecosystem in question?
  • 2. How will CC threats exacerbate existing threats?
  • 3. Focus on CC threats that are relatively well-established

Examples

NOVEL THREAT

EXISTING THREAT

Wetland complex

Estuarine ecosystem

Hydrologic regime: stream flow from melting snowpack

Extent and distribution of

salt marsh

Decline in stream flow

Loss of salt marsh

Reduced snowpack; decreased late season base flows

Agricultural water withdrawals, dams & diversions

Sea level rise

Strategies

Threat-based:

Energy, transportation,

cap&trade

Target-based:

enhance resilience

cc strategies can be proactive
Objectives and StrategiesCC strategies can be proactive
  • Focus on species and ecosystems in the middle of their range
  • Consider strategies to specifically address CC threats
  • Elevate strategies that address CC threats in addition to existing threats
  • Elevate strategies that address CC threats to multiple targets
  • MONITOR strategy effectiveness
  • Communicate impacts of climate change to partners and colleagues
slide9
Impact of climate change:

Increased atmospheric greenhouse gas concentrations

Strategy:

Forest conservation and restoration

slide10
Impact of climate change:

Species ranges shift altitudinally and latitudinally

Strategy:

Identify climate change refugia and concentrate management effort and

new acquisitions on portfolio sites in refugia

slide11
Impact of climate change:

Habitat fragmentation prevents dispersal to new habitats

Strategy:

Establish corridors to link current habitat to predicted new habitats

slide12
Impact of climate change:

Sea level rise

Strategy:

Vegetate coastal marshes as sea level rises and marshes shift inland

slide13
Impact of climate change:

Decreased late season baseflow

Strategy:

Restore and protect key freshwater wetlands, including riparian areas, to store water for late season flows

conclusions
Conclusions
  • Look at Conservation Planning through a Climate Change lens.
  • Anticipate the impacts of climate change on portfolio species and ecosystems.
  • Implement strategies to mitigate those impacts and increase target resilience
