III. Management Goals and Criteria economic objectives as well as the 1973 Agreement on the Conservation of Polar Bears. We acknowledge and support the conservation actions of the other Range States to the extent they contribute to recovery of the species. Fundamental Goal 4: Recognize the nutritional and cultural needs of native peoples with connections to polar bear populations, including the opportunity for continued subsistence harvest of polar bears. Local native communities throughout the Arctic have a long tradition of living with polar bears. Those communities have engaged in polar bear harvest consistent with long-standing traditions that provide for the nutritional and cultural needs of communities and have been integral to the success of polar bear conservation activities. Article III of the 1973 Agreement on the Conservation of Polar Bears allows harvest of polar bears in the exercise of traditional rights of local people. Congress recognized the cultural importance of subsistence harvest to Alaska Native peoples in both the MMPA and the ESA. The MMPA specifically allows non-wasteful harvest of marine mammals, including those that are depleted, by coastal-dwelling Alaska Native peoples (take of polar bears from the Chukchi Sea subpopulation is governed under Title V, 16 USC §1423). The ESA similarly exempts Alaska Native subsistence harvest from the prohibition on take of threatened or endangered species. Commercial trade is not authorized, however. This does not preclude creation and sale of authentic Alaska Native handicrafts and clothing as authorized by these two statutes. Both the MMPA and ESA acknowledge the conservation context of the subsistence exception by authorizing the Secretary to regulate such harvest if necessary (16 USC §1371(b), 16 USC §1539(e)). This fundamental goal is intended to provide future generations of Alaska Natives the opportunity to meet nutritional and cultural needs through the harvest of polar bears. Achievement of this goal will require the continued responsible management of harvest by Alaska Native peoples, other indigenous peoples, the United States, and other Range States. of people living and working in the coastal areas frequented by polar bears is a paramount concern. A secondary but important consideration for polar bear conservation is the outcome of human-bear interactions on polar bears. Frequent interactions with people pose a threat to polar bears, both directly, if bears have to be killed, and indirectly, through habituation to humans, food conditioning, and other possible risks. Fundamental Goal 6: Achieve polar bear conservation while minimizing restrictions to other activities within the range of the polar bear, including economic development. Local, regional, state, national, and global communities benefit from human activities in the Arctic, including tourism, recreation, oil and gas development, mining, shipping, and scientific research. In some cases, these activities may be compatible with polar bear conservation; in others, there may be conflicts. Finding strategies here in the United States that allow both would benefit multiple stakeholders. This goal reflects objectives in the administration’s “National Strategy for the Arctic Region” (White House 2013a), which calls on United States federal agencies to use integrated Arctic management to balance economic development, environmental protection, and cultural values. In the following three sections (organized by the MMPA, ESA, and other motivations, respectively), the Fundamental Goals are expressed as quantitative measures; for the goals related to the MMPA and ESA, criteria associated with conservation and recovery are provided. Where appropriate, these fundamental criteria are further described with stepped-down demographic and threats-based criteria (Table 1). Fundamental Goal 5: Continue to manage humanpolar bear interactions to ensure human safety and to conserve polar bears. The likelihood of interactions between humans and polar bears increases: as polar bears spend more time on shore due to a number of factors including receding sea ice; as their primary prey declines and they seek alternative food; as the human population near the Arctic coast increases; and as industrial activity in the Arctic increases.

III. Management Goals and Criteria Table 1. Three-tier framework for MMPA conservation criteria and ESA recovery criteria; and performance metrics for the remaining Fundamental Goals. The criteria are arranged in three tiers: fundamental (directly related to the fundamental goals); demographic (stepped-down to the level of population demographic rates); and threats-based (stepped-down further to the level of threats). For the fundamental goals (FG) not directly linked to MMPA or ESA, performance metrics are described, without additional tiers or performance thresholds. MMPA Conservation ESA Recovery Other Fundamental Goals Fundamental Criteria & Performance Metrics Conservation Criterion 1: The health and stability of the marine ecosystem, as evidenced by its capacity to support polar bears, are maintained, and each subpopulation of polar bears is maintained Recovery Criterion 1: The worldwide probability of persistence is at least 95% over 100 years. (FG1) AND as a significant functioning element of that ecosystem. (FG3) AND Conservation Criterion 2: Each subpopulation is managed so that its population size is above the maximum net productivity level relative to carrying capacity. (FG3) Demographic Criteria MMPA Demographic Criterion 1: The intrinsic growth rate of each subpopulation is above, and is expected to remain above, a minimum level that indicates the health of the marine ecosystem is not impaired; and the carrying capacity in each subpopulation is above, and is expected to remain above, 70% of mean historical carrying capacity, indicating that the stability of the marine ecosystem is not impaired. AND MMPA Demographic Criterion 2: Total human-caused removals in each subpopulation do not exceed a rate h (relative to the subpopulation size) that maintains the subpopulation above its maximum net productivity level relative to carrying capacity. Recovery Criterion 2: The probability of persistence in each recovery unit (ecoregion) is at least 90% over 100 years. (FG2) ESA Demographic Criterion 1: The mean adult female survival rate (at a density corresponding to maximum net productivity level and in the absence of direct human-caused removals) in each recovery unit is at least 93–96%, both currently and as projected over the next 100 years. AND ESA Demographic Criterion 2: The ratio of yearlings to adult females (at a density corresponding to maximum net productivity level) in each recovery unit is at least 0.1–0.3, both currently and as projected over the next 100 years. AND ESA Demographic Criterion 3: The carrying capacity, distribution, and connectivity in each recovery unit, both currently and as projected over the next 100 years, are such that the probability of persistence over 100 years is at least 90%. AND FG4: Cumulative take (all human-caused removals) level over the next 50 years for each subpopulation that includes parts of Alaska. FG5: Number of human-bear conflicts in Alaska that result in injury or death to humans or bears. FG6: Economic impacts of polar bear management actions, including direct and indirect expenses, and lost or foregone opportunities. Continued Polar Bear Conservation Management Plan 17
