SUPPLEMENTARY INFORMATION:
Introduction
We, the U.S. Fish and Wildlife Service (Service), announce the
availability of the ROD, which we developed in compliance with the
agency decision-making requirements of the National Environmental
Policy Act of 1969, as amended (42 U.S.C. 4321 et seq.; NEPA) and its
implementing regulations at 40 CFR 1506.6. We completed a thorough
analysis of impacts on the human environment in the Final EIS for
experimental removal of barred owls to benefit threatened northern
spotted owls. The Final EIS evaluates the impacts of eight action
alternatives and a no-action alternative related to: (1) Federal
involvement in barred owl removal experiments, and (2) the possible
issuance of a scientific collecting permit under the Migratory Bird
Treaty Act (16 U.S.C. 703-712; MBTA) for lethal and nonlethal take of
barred owls. The ROD documents the rationale for our decision.
Based on our review of the alternatives and their environmental
consequences as described in our Final EIS, we selected a Preferred
Alternative based on a combination of the features of Alternatives 2
and 3. The Preferred Alternative consists of a demography study
conducted on four study areas. The study would be conducted in western
Washington, western Oregon, and northwestern California. The action
alternatives vary by the number and location of study areas, the type
of experimental design, duration of the study, and the method of barred
owl removal.
Background
The Service listed the northern spotted owl (Strix occidentalis
caurina) as a threatened species under the Endangered Species Act (16
U.S.C. 1531 et seq.; Act) in 1990, based primarily on habitat loss and
degradation (55 FR 26114). As a result, conservation efforts for the
northern spotted owl have been largely focused on habitat protection.
While our listing rule noted that the long-term impact of barred owls
(Strix varia) on the spotted owl was of considerable concern, the scope
and severity of this threat was largely unknown at that time (55 FR
26114, p. 26190). Competition from barred owls is identified as one of
the main threats to the northern spotted owl in the 2011 Revised
Northern Spotted Owl Recovery Plan (Recovery Plan) (USFWS 2011, p. III-
62). The Recovery Plan summarized information available since our
listing rule and found that competition from barred owls now poses a
significant and immediate threat to the northern spotted owl throughout
its range (USFWS 2011, pp. B-10 through B-12). To address this threat,
the Recovery Plan recommends designing and implementing large-scale
controlled experiments to assess the effects of barred owl removal on
spotted owl site occupancy, reproduction, and survival (USFWS 2011, p.
III-65).
Historically, the barred owl did not occur in the Pacific
Northwest. In the past century, barred owls have expanded their range
westward, reaching the range of the northern spotted owl in British
Columbia by about 1959. Barred owl populations continue to expand
southward within the range of the northern spotted owl, the population
of barred owls behind the expansion-front continues to increase, and
barred owls now outnumber spotted owls in many portions of the northern
spotted owl's range (Pearson and Livezey 2003, p. 272).
There is strong evidence to indicate that barred owls are
negatively affecting northern spotted owl populations. Barred owls
displace spotted owls from high-quality habitat (Kelley et al. 2003, p.
51; Pearson and Livezey 2003, p. 274; Courtney et al., pp. 7-27 through
7-31; Gremel 2005, pp. 9, 11, 17; Hamer et al. 2007, p. 764; Dugger et
al. 2011, pp. 2464-1466), reducing their survival and reproduction
(Olson et al. 2004, p. 1048; Anthony et al. 2006, p. 32; Forsman et al.
2011, pp. 41-43, 69-70). In addition, barred owls may physically attack
spotted owls (Gutierrez et al. 2007, p. 187). These effects may help
explain declines in northern spotted owl territory occupancy associated
with barred owls in the Northwest, and reduced northern spotted owl
survivorship and sharp population declines in Washington (e.g., in
northern Washington, spotted owl populations declined by as much as 55
percent between 1996 and 2006) (Anthony et al. 2006, pp. 21, 30, 32;
[[Page 57172]]
Forsman et al. 2011, pp. 43-47, 65-66)). Without management
intervention, it is reasonable to expect that competition from barred
owls may cause extirpation of the northern spotted owl from all or a
substantial portion of its historical range, reducing its potential for
survival and recovery.
Public Involvement
On December 10, 2009, the Service published a notice of intent to
prepare an environmental impact statement related to experimental
removal of barred owls for the conservation benefit of threatened
northern spotted owls (notice of intent) in the Federal Register (74 FR
65546), to solicit participation of: Federal, State, and local
agencies; Tribes; and the public to determine the scope of the EIS and
provide input on issues associated with the proposed experiment. In
addition to the publication of the notice of intent, the scoping
process included informal stakeholder and agency consultations, and
electronic or mailed notification to over 1,000 interested parties.
Public scoping lasted until January 11, 2010. A scoping report is
included in Appendix B of the Final EIS.
In accordance with the NEPA, the Draft EIS was circulated for
public review and comment. The public review period was initiated with
the publication of the notice of availability in the Federal Register
on March 8, 2012 (77 FR 14036). We conducted one public meeting in
Seattle on May 3, 2012, and five informational webinars for the public.
Comments were due June 6, 2012. A summary of the comments and our
written responses are appended to the Final EIS. We published a notice
of availability of the Final EIS in the Federal Register on July 24,
2013 (78 FR 44588).
Alternatives
The action alternatives vary by the number and location of study
areas, the method of barred owl removal (lethal, or a combination of
lethal and nonlethal), and the type of experimental design (demography
vs. occupancy). All action alternatives are based on a simple treatment
and control study approach. Under this approach, study areas are
divided into two comparable segments. Barred owls are removed from the
treatment area but not from the control area. Spotted owl populations
are measured using the same methodology on both areas, and the
population measures (occupancy, survival, reproduction, and population
trend) are compared between the control and treatment areas.
The removal of barred owls under the experiment would occur over a
period of 3 to 10 years, depending on the alternative. The action
alternatives include from 1 to 11 study areas, including from 0.31 to
6.55 percent of the northern spotted owl's habitat. A brief description
of each alternative follows.
No-Action Alternative
Under the No-action Alternative, the Service would not conduct
experimental removal of barred owls, thus not implementing one of the
recovery actions set forth in the Recovery Plan (USFWS 2001, p. III-
65). Data that would inform future barred owl management strategies
would not be gathered.
Preferred Alternative
The Preferred Alternative is based on a combination of the features
of Alternatives 2 and 3. The Preferred Alternative consists of a
demography study located within four study areas. These study areas
include existing spotted owl demography study areas where long-term
monitoring of northern spotted owl populations has occurred (Lint et
al. 1999, p. 17; Lint 2005, p. 7) and areas with comparable levels of
spotted owl data. A combination of lethal and nonlethal removal methods
would be used.
Alternative 1
Alternative 1 consists of a demography study in a single study area
with existing pre-treatment spotted owl demography data. The study area
would be located within one of the nine existing spotted owl demography
study areas where long-term monitoring of northern spotted owl
populations has occurred (Lint et al. 1999, p. 17; Lint 2005, p. 7).
Only lethal removal methods would be used in this alternative.
Alternative 2
Alternative 2 consists of a demography study in three study areas,
which would be located within existing spotted owl demography study
areas and distributed across the range of the northern spotted owl. A
combination of lethal and nonlethal removal methods would be used.
Alternative 3
Alternative 3 consists of a demography study in two study areas.
Barred owl removal would occur outside of existing spotted owl
demography study areas, but within areas that have adequate data to
conduct pre-removal demography analyses. A combination of lethal and
nonlethal removal methods would be used.
Alternative 4
Alternative 4 includes two subalternatives, 4a and 4b. Each
subalternative consists of a demography study in two study areas
outside existing spotted owl demography study areas. Each
subalternative uses a combination of lethal and nonlethal removal
methods. Subalternatives 4a and 4b differ in that 4a delays barred owl
removal to collect pre-treatment data for comparison with treatment
data, whereas 4b starts removal immediately and foregoes pre-treatment
data collection.
Alternative 5
Alternative 5 consists of an occupancy study approach in three
study areas. Barred owl removal would occur on areas outside of
existing spotted owl demography study areas. Only lethal removal
methods would be applied in this alternative.
Alternative 6
Alternative 6 includes two subalternatives, 6a and 6b. Each
subalternative consists of an occupancy study in three study areas.
Barred owl removal would occur on areas outside of existing spotted owl
demography study areas. Each subalternative uses a combination of
lethal and nonlethal removal methods. Subalternatives 6a and 6b differ
in that 6a delays removal to collect pre-treatment data for comparison
with treatment data, whereas 6b starts removal immediately and foregoes
pre-treatment data collection.
Alternative 7
Alternative 7 consists of a combination of demography and occupancy
analyses across 11 study areas, some of which have current data. Three
existing spotted owl demographic study areas would be included within
these study areas. A combination of lethal and nonlethal removal
methods would be used.
Selected Alternative
We selected the Preferred Alternative developed following public
review of the Draft EIS. The Preferred Alternative consists of a
demography study in four study areas. Barred owl removal would occur on
the Cle Elum Study Area in Washington and the Hoopa (Willow Creek)
Study Area in California from Alternative 2, the Union/Myrtle (Klamath)
Study Area in southern Oregon from Alternative 3, and one half of the
combined Oregon Coast Ranges
[[Page 57173]]
and Veneta Study Areas in northern Oregon. This last study area is a
combination of study areas from Alternative 2 and 3. A combination of
lethal and non-lethal removal methods would be used.
Decision Rationale
Our decision is to adopt the Preferred Alternative as described in
the Final EIS for experimental removal of barred owls to benefit
threatened northern spotted owls. We provide a brief summary of our
decision below; for the full basis of our decision, please see the
Final EIS. We choose to implement an alternative with elements that
would provide for a strong, scientifically credible experiment with a
high power to detect the effect of the barred owl removal on spotted
owl populations, and that would provide results applicable across the
range of the northern spotted owl in a timely manner.
To provide for high scientific credibility and power to detect any
effect of the experimental removal of barred owls on spotted owl
populations, we selected a demography study approach utilizing study
areas with preexisting data on spotted owl populations and trends. The
use of a demography study approach and the long history of spotted owl
population data on these study areas provides for a very robust
experiment.
To ensure the results are applicable across the range of the
northern spotted owl, we selected four study areas distributed in
Washington, Oregon, and California. This includes study areas in
Washington with a long history of barred owl presence, high barred owl
density, and low spotted owl site occupancy. Oregon study areas have a
shorter history of high barred owl populations and greater spotted owl
site occupancy. The California study area is the most recently invaded,
has lower barred owl densities, and higher spotted owl site occupancy.
Thus, the selected alternative will provide information on the efficacy
of the removal in all types of barred owl population condition.
The combination of the number of study areas and the available pre-
treatment data provides for a timely result, with the study taking an
estimated 4 years of removal to reach significant results.
The use of a combination of lethal and non-lethal removal methods
allows us to reduce the number of barred owl that would be killed under
this study. To the extent that we are able to find organizations with
the appropriate permits, adequate facilities to provide a high quality
of care for the life of the bird, and an interest in having barred owls
for educational purposes, we would capture birds to fill the
opportunities. Our initial overtures to zoos and zoological parks
resulted in interest in placing five individual barred owls. We will
continue to look for opportunities to place barred owls, but given the
expense, difficulty, and type of facility needed, we do not anticipate
being able to place a large number of barred owls.
