SUPPLEMENTARY INFORMATION: We, the Fish and Wildlife Service (Service), 
announce the availability of the technical/agency draft recovery plan 
for the endangered Cumberland darter, a fish. The draft recovery plan 
includes specific recovery objectives and criteria that would be used 
to delist this fish under the Endangered Species Act of 1973, as 
amended (16 U.S.C. 1531 et seq.; Act). We request review and comment on 
this draft recovery plan from local, State, and Federal agencies, and 
the public.

Background

    The Act requires the development of recovery plans for listed 
species, unless such a plan would not promote the conservation of a 
particular species. Recovery plans describe actions considered 
necessary for conservation of species, establish criteria for 
delisting, and estimate time and cost for implementing recovery 
measures. Section 4(f) of the Act requires us to provide public notice 
and an opportunity for public review and comment during recovery plan 
development. We will consider all information presented during a public 
comment period prior to approval of each new or revised recovery plan. 
We and other Federal agencies will take these comments into 
consideration in the course of implementing approved recovery plans.

About the Species

    We listed the Cumberland darter (Etheostoma susanae) as endangered 
under the Act on September 8, 2011 (76 FR 48722). The Cumberland darter 
is a small fish endemic to the upper Cumberland River basin, above 
Cumberland Falls, in Kentucky and Tennessee. Cumberland darters occur 
in 9 widely separated populations (total of 16 streams) in southeastern 
Kentucky and north-central Tennessee. No population estimates or status 
trends are available; however, survey results by Thomas (2007) suggest 
that the species is uncommon or occurs in low densities across its 
range.
    Cumberland darters are known from streams ranging in size from 
small, second order tributaries to larger, fourth order streams such as 
Jellico Creek, Whitley County, Kentucky. Little is known of the 
species' life history or microhabitat suitability, but it is often 
encountered in pools or shallow runs of low-to-moderate-gradient 
sections of streams with sand, silt, or sand-covered bedrock 
substrates. Most of these habitats contain isolated boulders and large 
cobble that the species likely uses as cover.
    We designated critical habitat for the Cumberland darter on October 
16, 2012 (77 FR 63604). A total of 54 river miles (86 rkm) were 
designated, including 13 streams in McCreary and Whitley Counties, 
Kentucky, and Campbell and Scott Counties, Tennessee.

Threats

    The majority of streams within the upper Cumberland River basin 
have been modified from their historical condition due to a number of 
anthropogenic activities such as agriculture, logging, residential 
development, road construction, and surface coal mining. As a result of 
these activities and associated stressors (e.g., siltation), the 
Cumberland darter has been extirpated from at least six streams and is 
now restricted to nine isolated watersheds. Limiting factors include 
the following: (1) Anthropogenic activities that cause siltation, 
disturbance of riparian corridors, and changes in channel morphology; 
(2) water quality degradation caused by a variety of nonpoint-source 
pollutants; and (3) naturally small population size and reduced 
geographic range.

Recovery Plan Components

    The primary goal of this recovery plan is to recover Cumberland 
darter populations to the point that listing under the Act is no longer 
necessary. To achieve these goals, it is necessary to produce self-
sustaining, viable populations that possess healthy, long-term 
demographic and genetic trends (e.g., evidence of multiple age classes 
and continued recruitment, high genetic diversity), and that are no 
longer threatened by any of the factors discussed above.

Management Units

    For this Recovery Plan, we identify nine management units for the 
Cumberland Darter (refer to the associated Recovery Implementation 
Strategy, Figure 1). Based on the species' current distribution (refer 
to the associated Species Biological Report, Figures 1 and 2) and our 
knowledge of the species' movement patterns, we consider each 
management unit to

[[Page 14290]]

represent a separate population. As genetic analyses are completed and 
more is known about the species' gene flow and genetic structure, it 
may be necessary to adjust or modify unit boundaries. All stream 
reaches within the species' historical range that are not specifically 
identified in the following management units, should not immediately be 
excluded from recovery activities if new information indicates these 
areas are necessary to prevent local extirpation or to facilitate 
recovery.
    The management units are as follows:
    Management Unit 1: The boundaries of this management unit 
correspond to critical habitat units 1 (Bunches Creek) and 2 (Calf Pen 
Fork), which are located entirely within the Daniel Boone National 
Forest (DBNF).
    Management Unit 2: The boundaries of this management unit 
correspond to critical habitat units 7 (Kilburn Fork) and 8 (Laurel 
Fork). The majority of this management unit (73 percent) is located 
within the DBNF.
    Management Unit 3: The boundaries of this management unit 
correspond to critical habitat unit 6 (Cogur Fork). The majority of 
this management unit (69 percent) is located within the DBNF.
    Management Unit 4: The boundaries of this management unit 
correspond to critical habitat units 4 (Barren Fork) and 5 (Indian 
Creek), which are located entirely within the DBNF.
    Management Unit 5: The boundaries of this management unit 
correspond to critical habitat units 9 (Laurel Creek), 10 (Elisha 
Branch), and 11 (Jenneys Branch), and a 7.4-km (4.6-mi) segment of 
Bridge Fork. The majority of this management unit (96 percent) is 
located within the DBNF.
    Management Unit 6: This management unit corresponds to critical 
habitat units 13 (Jellico Creek), 14 (Rock Creek), and 15 (Capuchin 
Creek). A portion of this management unit (29 percent) is located 
within the DBNF.
    Management Unit 7: The boundaries of this management unit 
correspond to critical habitat unit 3 (Youngs Creek). This unit is 
located almost entirely on private land, except for any small amount 
that is publicly owned in the form of bridge crossings and road 
easements.
    Management Unit 8: The boundaries of this management unit 
correspond to critical habitat unit 12 (Wolf Creek). This unit is 
located almost entirely on private land, except for any small amount 
that is publicly owned in the form of bridge crossings and road 
easements.
    Management Unit 9: This management unit does not correspond to a 
critical habitat unit because the species was thought to be extirpated 
from Laurel Fork when the critical habitat rule was published in 2012. 
The species was rediscovered in Laurel Fork (of Clear Fork) by the 
Kentucky State Nature Preserves Commission (KSNPC) and the Service in 
2014 (Service unpublished data). This management unit is comprised of 
an approximate 16.7-km (10.4-mi) reach of Laurel Fork that extends from 
the mouth of Laurel Fork in Campbell County, Tennessee, upstream to 
Laurel Fork-Buffalo Creek Road in Whitley County, Kentucky. No 
collection records exist for the Tennessee portion of this management 
unit (Campbell and Claiborne Counties); however, recent collection 
records exist for areas near the Kentucky-Tennessee border, and 
suitable habitat is present throughout the Tennessee portion of the 
stream. This unit is located primarily on private property, except for 
a 6.6-km (4.1-mi) reach on the western side (right descending bank) of 
Laurel Fork in Archer-Benge State Nature Preserve, a 7.5-km\2\ (1,864-
ac) tract in Whitley County, Kentucky, and any small amount that is 
publicly owned in the form of bridge crossings and road easements.

Recovery Criteria

    The Cumberland darter should be considered for removal from the 
List of Endangered and Threatened Wildlife when:
    (1) Management Units 1-9 or Management Units 1-7, 9, and one 
additional stream within the species' historical range (e.g., Sanders 
Creek) are determined to be protected from present and foreseeable 
habitat threats through recovery efforts like land acquisition, 
conservation agreements and easements, stewardship, outreach, adequate 
regulatory oversight and enforcement, or other similar actions;
    (2) Instream habitat quality (substrate, flows, water quality) in 
these management units is sufficient, as defined by recovery tasks 3.1 
and 3.2, to meet the species' life history requirements; and
    (3) A viable population (as defined in the recovery plan) must 
occur within each of these management units.
