Utility
• Climate suitability is a strong
indicator of where viable
populations may be able to
exist.
•
Other controlling factors can
be manipulated through
management.
•
Thus, knowledge of climate
suitability is a first filter for
prioritizing research and
management.

Climate Envelope Modeling Conclusions
In the Northern Rockies and Yellowstone, subalpine forests are high in
vulnerability to climate change and lower treeline forests are pushed
substantially upslope.
These results might suggest that upper and lower treeline forests are
least resilient to climate change, beetles, fire.
In these zones of forest decline, ecosystem services relating to
snowpack, runoff, and food and habitat for other species will be
reduced.
Climate suitability for tree species is an important filter for prioritizing
research and management.

Management Implications for Whitebark Pine
RCP 4.5
Core Habitat. Manage to retain the
species in these vitally important
zones.
Deteriorating Habitat.
• Give up?
• Manage towards Scenarios of
Viability?
RCP 8.5
Future habitat. Manage for natural
colonization and assisted
colonization.

Date and Venue
April 9, 2015: USGS Science Center, Bozeman, MT
Objectives
1. Synthesize results from the NASA Landscape Climate Change Vulnerability
Project (LCCVP)* study on climate change, ecological response,
vulnerability assessment.
2.
Identify management-relevant issues for vegetation in the GYE based on
LCCVP, Northern Rockies Adaptation Partnership, Greater Yellowstone
Coordinating Committee, and related activities.
3.
Attempt to “close the loop” on the Climate Smart Cycle by outlining
approaches for developing/evaluating/implementing/monitoring climate
adaptation strategies.
