SUPPLEMENTARY INFORMATION:

Background

    Recovery plans describe actions considered necessary for the 
conservation and recovery of species listed under the Endangered 
Species Act of 1973 (ESA), as amended (16 U.S.C. 1531 et seq.). The ESA 
requires that recovery plans incorporate (1) Objective, measurable 
criteria that, when met, would result in a determination that the 
species is no longer threatened or

[[Page 29920]]

endangered; (2) site-specific management actions necessary to achieve 
the plan's goals; and (3) estimates of the time required and costs to 
implement recovery actions. The ESA requires the development of 
recovery plans for listed species unless such a plan would not promote 
the recovery of a particular species. NMFS' goal is to restore 
endangered and threatened Steller sea lion (Eumetopias jubatus) 
populations to the point where they are again secure, self-sustaining 
members of their ecosystems and no longer need the protections of the 
ESA. NMFS will consider all substantive comments and information 
presented during the public comment period in the course of finalizing 
this Recovery Plan.
    The Steller sea lion was listed as a threatened species under the 
ESA on April 5, 1990 (55 FR 12645), due to substantial declines in the 
western portion of the range. In contrast, the eastern portion of the 
range (in southeastern Alaska and Canada) was increasing at 3 percent 
per year. Critical habitat was designated on August 27, 1993 (58 FR 
45269), based on the location of terrestrial rookery and haulout sites, 
spatial extent of foraging trips, and availability of prey items. In 
1997, the Steller sea lion population was split into a western distinct 
population segment (DPS) and an eastern DPS based on demographic and 
genetic dissimilarities (62 FR 30772). Due to the persistent decline, 
the western DPS was reclassified as endangered, while the increasing 
eastern DPS remained classified as threatened. Through the 1990s the 
western DPS continued to decline. However, the western population has 
shown as increase of approximately 3 percent per year between 2000 and 
2004. This was the first recorded increase in the population since the 
1970s. Based on recent counts, the western DPS is currently about 
44,800 animals and may be increasing due to higher juvenile and adult 
survival. However, it remains unclear whether Steller sea lion 
reproduction has also improved and whether the observed 3 percent 
annual population growth will continue. The eastern DPS is currently 
between 45,000 and 51,000 animals, and has been increasing at 3 percent 
per year for 30 years.
    The first recovery plan was completed in December 1992 and covered 
the entire range of the threatened species. However, the recovery plan 
became obsolete after the split into two DPSs in 1997. Nearly all of 
the recovery actions contained in the plan had also been completed. 
NMFS assembled a new recovery team in 2001 to revise the first plan. 
The recovery team completed the draft revision in March 2006 and 
forwarded the plan to NMFS with unanimous endorsement by the 17 team 
members who represented the fishing industry, Alaska Natives, fishery 
and marine mammal scientists, and environmental organizations.
    The Plan contains: (1) A comprehensive review of Steller sea lion 
ecology, (2) a review of previous conservation actions, (3) a threats 
assessment, (4) biological and recovery criteria for downlisting and 
delisting, (4) actions necessary for the recovery of the species (78 
discrete actions for the western DPS), and (5) estimates of time and 
cost to recovery.
    The threats assessment concludes that the following threats are 
relatively minor: (1) Alaska Native subsistence harvest, (2) illegal 
shooting, (3) entanglement in marine debris, (4) disease, and (5) 
disturbance from vessel traffic and scientific research. Although much 
has been learned about Steller sea lions and the North Pacific 
ecosystem, considerable uncertainty remains about the magnitude and 
likelihood of the following potential threats (relative impacts in 
parenthesis): competition with fisheries (potentially high), 
environmental variability (potentially high), killer whale predation 
(potentially high), incidental take by fisheries (medium), and toxic 
substances (medium).
    In contrast, no threats were identified for the eastern DPS. 
Although several factors affecting the western DPS also affect the 
eastern DPS (e.g., environmental variability, killer whale predation, 
toxic substances, disturbance), these threats do not appear to be 
limiting recovery given the long term sustained growth of the 
population. However, concerns exist regarding global climate change and 
the potential for the southern part of the range (i.e., California) to 
be adversely affected. Future monitoring should target this southern 
portion of the range.
    The Plan identifies 78 substantive actions needed to achieve 
recovery of the western DPS by addressing the broad range of threats. 
The Plan highlights three actions (detailed below) that are especially 
important to the recovery program for the western DPS:
    1. Maintain current fishery conservation measures: After a long 
term decline, the western DPS appears to be stabilizing. The first 
slowing of the decline began in the 1990s suggesting that the 
management measures implemented in the early 1990s may have been 
effective in reducing anthropogenic effects (e.g., shooting, 
harassment, and incidental take). The apparent population stability 
observed in the last 6 years is correlated with comprehensive fishery 
management measures implemented since the late 1990s. The current suite 
of management actions (or their equivalent protection) should be 
maintained until substantive evidence demonstrates that these measures 
can be reduced without limiting recovery.
    2. Design and implement an adaptive management program to evaluate 
fishery conservation measures: Due to the uncertainty in how fisheries 
affect Steller sea lions and their habitat, and the difficulty in 
extrapolating from individual scientific experiments, a properly 
designed adaptive management program should be implemented. This type 
of program has the potential to assess the relative impact of 
commercial fisheries and to better distinguish the impacts of other 
threats (including killer whale predation). This program will require a 
robust experimental design with replication at the proper temporal and 
spatial scales with the appropriate levels of commercial fishing as 
experimental treatments. It will be a challenge to construct an 
adaptive management plan that meets the requirements of the ESA, is 
statistically sufficient, and can be implemented by the commercial 
fisheries. Acknowledging these hurdles, a significant effort must be 
made to determine the feasibility of such a program.
    3. Continue population monitoring and research on the key threats 
potentially impeding sea lion recovery: Estimates of population 
abundance, trend, distribution, health, and essential habitat 
characteristics are fundamental to Steller sea lion management and 
recovery. Further, current information on the primary threats is 
insufficient to assess their impact on recovery. Focused research is 
needed on how these threats impact sea lion population growth and how 
they may be mitigated in order to facilitate recovery. In addition to 
studies on individual threats, the dynamics between threats needs to be 
better understood to assess the cumulative effects on sea lions.
    Criteria for reclassification of Steller sea lion are included in 
the Plan. In summary, the western DPS of Steller sea lion may be 
reclassified from endangered to threatened when all of the following 
have been met: (1) Counts of non-pups in the U.S. portion of the DPS 
have increased for 15 years (on average); (2) the population ecology 
and vital rates in the U.S. region are consistent with the observed 
trend; (3) the non-pup trends in at least 5 of the 7 sub-regions are 
consistent with the

[[Page 29921]]

overall U.S. trend, and the population trend in any two adjacent sub-
regions can not be declining significantly; and (4) all five listing 
factors are addressed.
    The western DPS of Steller sea lion may be delisted when all of the 
following conditions have been met: (1) Counts of non-pups in the U.S. 
portion of the DPS have increased at an average annual rate of 3 
percent for 30 years (i.e., 3 generations); (2) the population ecology 
and vital rates in the U.S. region are consistent with the observed 
trend; (3) the non-pup trends in at least 5 of the 7 sub-regions are 
consistent with the overall U.S. trend; the population trend in any two 
adjacent sub-regions can not be declining significantly, and the 
population trend in any single sub-region can not have declined by more 
than 50 percent; and (4) all five listing factors are addressed.
    The eastern DPS of Steller sea lion may be delisted when all of the 
following have been met: (1) The population has increased at an average 
rate of 3 percent per year for 30 years (i.e., 3 generations); (2) the 
population ecology and vital rates are consistent with the observed 
trend; and (4) all five listing factors are addressed.
    Time and cost for recovery actions are contained in the Plan. The 
recovery program for the western DPS will cost $93,840,000 for the 
first 5 fiscal years and $430,425,000 to full recovery assuming 30 
years for recovery starting in 2000, and using year 5 costs as the cost 
for all future years. The recovery program for the eastern DPS will 
cost $150,000 for the first year and $1,050,000 total for 10 years of 
post-delisting monitoring.
    In accordance with the 1994 peer review policy, NMFS solicited peer 
review on the draft Plan. Reviews were requested from 5 scientists and 
managers with expertise in recovery planning, statistical analyses, 
fisheries, and marine mammals. The reviews of the Plan were generally 
favorable. In particular, the reviewers found the recovery criteria to 
be well reasoned and supported. In response to reviewer's comments, 
changes were made to the plan to clarify the recovery criteria, add 
delisting criteria for the western DPS, and focus priorities and 
actions. NMFS anticipates that many of the recommendations made by the 
reviewers will be addressed in an implementation and research plan 
which NMFS intends to develop after the Plan is finalized. Reviewers' 
comments and NMFS' formal response to the comments will be provided in 
detail in the final recovery plan.
