IV. Conservation Management Strategy<br />
d. Other measures of achievement<br />
As stated previously, fundamental Goals 4, 5, and 6<br />
are not derived directly from statute, but instead<br />
are expressions of other societal values that could be<br />
affected by polar bear management. Performance<br />
requirements do not need to be prescribed for these<br />
goals (as they do for ESA recovery criteria and<br />
MMPA conservation criteria). It will be important,<br />
however, to address achievement of these goals,<br />
particularly to provide an adaptive feedback loop<br />
for improving future conservation actions. If we<br />
are successful in managing other threats to polar<br />
bears such that populations persist, then we will<br />
be better positioned to successfully recognize the<br />
nutritional and cultural traditions of Native peoples<br />
with connections to polar bears (Fundamental Goal<br />
4). Monitoring the MMPA Demographic Criteria<br />
specified above requires collection of data on the<br />
number of lethal removals of polar bears, but to<br />
put this into context data should be collected on the<br />
broader effort to manage human-polar bear interactions<br />
and the relative success of various deterrence<br />
strategies (Fundamental Goal 5). Finally, there<br />
should be a qualitative assessment of our success at<br />
achieving polar bear conservation while minimizing<br />
restrictions to other activities, including economic<br />
development (Fundamental Goal 6).<br />
2. Research needs for United States polar bear subpopulations<br />
The previous section focused on monitoring<br />
demographic and threats-based criteria to inform<br />
management actions and adjustments. This section<br />
focuses on research designed to develop or refine the<br />
criteria that serve as proxies for our fundamental<br />
goals, improve monitoring of these criteria, and<br />
improve our understanding of the relationships (e.g.,<br />
between sea-ice availability and vital rates) and<br />
ecosystem dynamics that cumulatively determine<br />
polar bear persistence. We divide research into<br />
the following five areas: (1) population dynamics<br />
and distribution; (2) habitat ecology; (3) health and<br />
nutritional ecology; (4) nutritional and cultural use<br />
of polar bears; and (5) human-polar bear interactions.<br />
We briefly review these areas of research and<br />
a list of representative research projects is attached<br />
(Appendix B). Specific priorities and cost estimates<br />
for these areas will be developed by the Recovery<br />
Implementation Team and Team members. We envision<br />
a dynamic and adaptive process through which<br />
this Plan is updated to reflect new information, and<br />
research planning is updated to reflect the living<br />
Conservation Management Plan document. We also<br />
envision the active engagement of current and new<br />
partners in these activities including Universities,<br />
other Federal, State, and local agencies along with<br />
industry and non-governmental entities.<br />
needed to measure progress towards persistencebased<br />
goals. Where possible and appropriate, we<br />
will pursue research on population dynamics and<br />
distribution of our shared populations with our<br />
international partners.<br />
Habitat ecology. Under this research area, we will<br />
study the response of polar bear subpopulations<br />
to biotic and abiotic changes in the environment,<br />
including intermediate effects on primary (seals)<br />
and alternate (e.g., stranded marine mammals) prey.<br />
This will provide an improved understanding of the<br />
mechanistic links between habitat and demographics.<br />
Further research is also needed to understand<br />
linkages between atmospheric concentrations of<br />
GHG, sea ice, and polar bear resource selection and<br />
demographics.<br />
Population dynamics and distribution. Research in<br />
this area is intended to improve our understanding<br />
of the relationship between polar bears and the<br />
environment. This research will provide insights into<br />
how factors such as sea ice and prey abundance and<br />
availability affect polar bear distribution and vital<br />
rates. We have learned from research and monitoring<br />
on the two polar bear subpopulations shared<br />
by the United States that physical and biological<br />
differences among populations may affect how polar<br />
bears respond to habitat loss associated with climate<br />
change, especially in the near term. Long-term<br />
studies of subpopulation status (e.g., including vital<br />
rates used as demographic criteria) and trends are<br />
