SUPPLEMENTARY INFORMATION: We, the U.S. Fish and Wildlife Service
(Service), announce the availability of the draft recovery plan for the
endangered Poweshiek skipperling (Oarisma poweshiek) for public review
and comment. The Poweshiek skipperling is a small prairie butterfly
most often found in remnants of native prairies and fens. The draft
recovery plan includes objective, measurable criteria and management
actions as may be necessary for removal of the species from the Federal
List of Endangered and Threatened Wildlife. We request review and
comment on this draft recovery plan from local, State, and Federal
agencies, and the public.
Recovery Planning
Section 4(f) of the Endangered Species Act of 1973, as amended
(Act; 16 U.S.C. 1531 et seq.), requires the development of recovery
plans for listed species, unless such a plan would not promote the
conservation of a particular species. Also pursuant to section 4(f) of
the Act, a recovery plan must, to the maximum extent practicable,
include (1) a description of site-specific management actions as may be
necessary to achieve the plan's goals for the conservation and survival
of the species; (2) objective, measurable criteria that, when met,
would support a determination under section 4(a)(1) that the species
should be removed from the List of Endangered and Threatened Species;
and (3) estimates of the time and costs required to carry out those
measures needed to achieve the plan's goal and to achieve intermediate
steps toward that goal.
Species Background
The Poweshiek skipperling once ranged throughout the upper Midwest,
from Illinois and Iowa in the south, to Michigan in the east, to North
Dakota and South Dakota in the west, and southern Manitoba in the
north. Currently, populations of the Poweshiek skipperling are known to
occur in Michigan and Manitoba, Canada, and possibly in Wisconsin.
It is not known exactly what led to the decline in the species;
however, populations are likely influenced by degradation and
destruction of habitat through conversion of native prairie to cropland
or development; ecological succession to woody vegetation; encroachment
of invasive species; past and present fire, haying, or grazing
management that degraded or destroyed the species' habitats; flooding;
and, groundwater depletion, alteration, and contamination.
Additionally, biocide use may have direct or indirect effects on
Poweshiek skipperlings, compounding the effects of habitat curtailment.
The remaining populations of the Poweshiek skipperling are small and
isolated, and thus they are vulnerable to the effects of small
population dynamics, further compounding the effects of other
stressors.
Under the Act, the Service added the Poweshiek skipperling to the
Federal List of Endangered and Threatened Wildlife as an endangered
species on October 23, 2014 (79 FR 63671).

Recovery Criteria
The draft recovery criteria are summarized below. For the recovery
strategy, management actions, and estimated time and costs associated
with recovery, refer to the Draft Recovery Plan for the Poweshiek
Skipperling (see ADDRESSES for document availability).
The ultimate recovery goal is to remove the Poweshiek skipperling
from the Federal List of Endangered and Threatened Wildlife
(``delist'') by ensuring the long-term viability of the species in the
wild. In the recovery plan, we define the following criteria for
reclassification (``downlisting'' from endangered to threatened) and
delisting based on the best available information on the species.
Downlisting Criteria
To downlist the Poweshiek skipperling, the following criteria
should be achieved:
1. Conservation Unit 1 (Southeastern Manitoba, Northwestern
Minnesota, and Northeastern North Dakota) Criteria: 6 healthy
populations, with at least two populations in each of Canada and the
United States.
2. Conservation Unit 2 (Southeastern North Dakota, Central and
Southwestern Minnesota, Northeastern South Dakota, and Central and
Northern Iowa) Criteria: 23 healthy populations distributed throughout
the unit.
3. Conservation Unit 3 (Southeastern Wisconsin and Northeastern
Illinois) Criteria: 2 healthy populations.
4. Conservation Unit 4 (Michigan) Criteria: 5 healthy populations.
A healthy Poweshiek skipperling population is demographically,
genetically, and physically robust and occupies large areas of high-
quality remnant prairie habitat.
Delisting Criteria
To delist the Poweshiek skipperling, the following criteria should
be achieved:
1. Downlisting criteria have been met.
2. Threats and causes of decline have been reduced or eliminated,
and mechanisms are in place that provide a high level of certainty that
the downlisting criteria will continue to be met into the foreseeable
future.
