Addressing Uncertainty
Understanding How Birds Respond to Change

We live in a rapidly changing global environment. Because of
differing emission scenarios, climate predictions, and ecosystem
models, we may not be able to accurately predict the future, other than
knowing we face an uncertain but certainly altered future climate.
Successful conservation will require that solutions address the
likelihood of our altered environment strategically and not be
paralyzed by it.
Uncertainty can be reduced by developing and implementing effective
programs to monitor how birds respond to climate change. Climate change
in combination with numerous threats is creating environments not
previously experienced by birds. Monitoring data are invaluable in
making informed decisions in a changing world. We have limited
information about many of the species that are most vulnerable to
climate change--birds that live in the oceans, in the arctic and alpine
habitats, and along the coasts. Focusing monitoring on species that
show the highest potential vulnerability will provide the most relevant
indicator of how birds are adapting to environmental change.
Without additional information on how birds are responding to the
effects of climate change, we will be unable to adjust our conservation
and management strategies. Well-designed monitoring systems will also
be needed to evaluate the effectiveness of the strategies used to
counteract effects of climate change on bird populations.
Bird monitoring is usually a passive indicator of change, without
providing knowledge regarding causes or possible responses to change.
It is important, of course, to know when bird populations are declining
and require conservation attention, but the designs of most existing
monitoring programs have limited utility in interpreting system change
and the response of birds, and must therefore be improved. We recommend
that the nation’s current monitoring programs be modified to:
• Improve the design of many monitoring programs to allow analysis
separating the influence of climate change on population changes from
impacts caused by other environmental factors, as well as synergistic
interactions between climate and other factors affecting birds.
• Focus on the status of species most sensitive to climate
change.
• Design and use monitoring systems and information to inform
conservation
and land management decisions.
