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 />
