[Docket No. FWS-R2-ES-2012-0073; 4500030113]
Endangered and Threatened Wildlife and Plants; 90-Day Finding on
a Petition To List Phoenix dactylifera `Sphinx' (Sphinx Date Palm)
AGENCY: Fish and Wildlife Service, Interior.
ACTION: Notice of 90-day petition finding.
-----------------------------------------------------------------------
SUMMARY: We, the U.S. Fish and Wildlife Service (Service), announce a
90-day finding on a petition to list Phoenix dactylifera `Sphinx'
(sphinx date palm) as endangered or threatened under the Endangered
Species Act of 1973, as amended (Act). We find that the petition does
not present substantial scientific or commercial information indicating
that the petitioned action may be warranted. We find that the petition
does not identify an entity that is listable under the Act. Therefore,
we are not initiating a status review for the sphinx date palm in
response to this petition.
DATES: The finding announced in this document was made on December 4,
2012.
ADDRESSES: This finding is also available on the Internet at http://www.regulations.gov at [Docket No. FWS-R2-ES-2012-0073]. Supporting
documentation we used in preparing this finding is available for public
inspection, by appointment, during normal business hours at the Arizona
Ecological Services Office, 2321 West Royal Palm Road, Suite 103,
Phoenix, Arizona 85021-4951. Please submit any new information,
materials, comments, or questions concerning this finding to the above
address.
FOR FURTHER INFORMATION CONTACT: Steve Spangle, Field Supervisor,
Arizona Ecological Services Office (see ADDRESSES), by telephone at
(602) 242-0210, or by facsimile to (602) 242-2513. If you use a
telecommunications device for the deaf (TDD), please call the Federal
Information Relay Service (FIRS) at 800-877-8339.
SUPPLEMENTARY INFORMATION:
Background
Section 4(b)(3)(A) of the Act (16 U.S.C. 1531 et seq.), requires
that we make a finding on whether a petition to list, delist, or
reclassify a species presents substantial scientific or commercial
information indicating that the petitioned action may be warranted. We
are to base this finding on information provided in the petition,
supporting information submitted with the petition, and information
otherwise available in our files at the time that the petition was
submitted to us. To the maximum extent practicable, we are to make this
finding within 90 days of our receipt of the petition, and to publish
our notice of the finding promptly in the Federal Register.
Our standard for substantial scientific or commercial information
within the Code of Federal Regulations (CFR) with regard to a 90-day
petition finding is ``that amount of information that would lead a
reasonable person to believe that the measure proposed in the petition
may be warranted'' (50 CFR 424.14(b)). If we find that substantial
scientific or commercial information for a listable entity was
presented, we are required to promptly conduct a species status review,
which we subsequently summarize in a 12-month finding.
Petition History
On July 11, 2011, we received a petition dated July 7, 2011, from
Richard C. Malone, on behalf of the Mountgrove Property Owners
Association (petitioner), requesting that the single existing grove of
Phoenix dactylifera `Sphinx' (sphinx date palm) be listed as endangered
under the Act. For the purposes of this document, we will hereafter
refer to Phoenix dactylifera `Sphinx' as the sphinx date palm.
The petition discusses the origin and taxonomy of the sphinx date
palm, and provides details of its life history. The petitioner mentions
threats to the entity, and provides brief examples of potential
population declines. The petition also discusses the petitioners' views
on the advantages of protection for the sphinx date palm for research,
education, propagation, as well as the economic advantages of the
grove's production of high-quality fruit. The petition includes
citations for various references and resources used to support the
statements in the petition.
The petition clearly identified itself as such and included the
requisite identification information for the petitioners, as required
by 50 CFR 424.14(a). This finding addresses the petition. Below, we
address the petitioner's request to list Phoenix dactylifera `Sphinx'
as endangered.
Species Information
All information in this section is from the petition. The Service
has no information in its files on the sphinx date palm beyond that
presented in the petition.
The grove in Phoenix consists of 450 mature trees and is the only
known stand (contiguous area occupied by trees of similar type) of
sphinx date palm. The grove is located in the Mountgrove district,
south of Lafayette Boulevard, north of the Arizona canal, bordered by
46th Place on the west and 47th place on the east in the Arcadia area
of central Phoenix. There are a few additional individual palms in the
Phoenix Metro and Yuma areas of Arizona, and two sphinx date palms are
reported to exist in California.
The petitioner does not provide descriptive information specific to
the sphinx cultivar. They do provide information for the date palm
(Phoenix dactylifera Linnaeus), the taxon from which the sphinx date
palm was cultivated. The date palm is an erect palm with solitary or
clustered stems. It can reach heights of 30 to 35 meters (m) (100 to
115 feet (ft)) and grow to diameters of 50 centimeters (cm) (20 inches
(in)). The trunk is covered from the ground up with overlapping
diamond-shaped, woody leaf bases. Feather-like green-gray pinnae
(leaves) are arranged irregularly on long (3 to 5 m (9 to 16 ft))
petioles (stalk or stem that connects the pinnae to the plant).
Inflorescences (arrangements or clusters of multiple flowers on a stem)
have waxy, cream-colored flowers and grow to 1 m (3.3 ft) on male
plants and 2 m (2.6 ft) on female plants (these palms are dioecious;
that is, individual palms contain either male reproductive parts or
female reproductive parts).
The sphinx date palm has a lifespan of 100 to 130 years.
Reproduction in the cultivar is vegetative (asexual; only one plant is
involved and the offspring is genetically identical to its parent).
Propagation is accomplished by removing offshoots (lateral shoot from
the main stem of the plant) from mature palms. These offshoots must
contain their own root ball (main mass of roots at the base of a
plant). Propagation in this slow-growing cultivar is a long process,
spanning 3 generations of 8 years each. Approximately 25 years were
required to propagate the 450 offshoots needed to plant the grove.
Pollination, and thus fruit production, is fully dependent on human
intervention as male palms are not sufficiently numerous or near to
date-bearing (female) palms for pollination to occur by natural means.
It is believed that Southwest Asia is the native region of the
sphinx date palm's parent taxon, the date palm; however, its origin is
not known with certainty. The sphinx date palm was
[[Page 71758]]
described in the late 1910s or early 1920s from a grove in Phoenix,
Arizona, where it had been propagated from a seedling around 1917. The
sphinx cultivar is thought to be a chance hybrid between Hayani (a
variety of date palm) and another heirloom (a plant cultivated for
multiple human generations and typically particular to a given region).
Currently this entity is known only from cultivation.
The petition consistently refers to the sphinx date palm as a
cultivar of P. dactylifera. The International Code of Nomenclature for
Cultivated Plants defines a cultivar as ``an assemblage of plants that
(a) has been selected for a particular character or combination of
characters, (b) is distinct, uniform, and stable in these characters,
and (c) when propagated by appropriate means, retains those
characters'' (Art. 2.3). It further notes that cultivars vary in origin
and modes of reproduction, and that plants ``which are asexually
propagated from any part of a plant * * * may form a cultivar.'' By
this definition, and as indicated in the petition, the sphinx date palm
is a cultivar of the date palm (Phoenix dactylifera Linnaeus).
Previous Federal Actions
There have been no previous Federal actions for this entity.
Evaluation of Listable Entity
Upon receipt of a petition to list, delist, or reclassify a
species, we are to consider whether such petition ``clearly indicates
the administrative measure recommended and gives the scientific and any
common name of the species involved'' (50 CFR 424.14(b)(2)(i)). Under
the Act, a species is defined as including any subspecies of fish or
wildlife or plants, and any distinct population segment (DPS) of any
species of vertebrate fish or wildlife which interbreeds when mature
(16 U.S.C. 1532).
The sphinx date palm, like many vascular plants, is of hybrid
origin. We acknowledge that hybridization is an important mechanism of
plant speciation, as hybrids can display new phenotypes and promote
adaptive evolution. We also acknowledge that it is conceivable that
over time, the sphinx date palm could become sufficiently
reproductively isolated to accrue substantial genetic distinction from
its parent species to become a species itself. At this time, however,
Phoenix's grove of sphinx date palms is a collection of individuals
which does not represent a cohesive population entity with an
evolutionary lineage separate from its parent species. In modern
taxonomic practice, entities such as the sphinx date palm hybrid do not
constitute a species.
The sphinx date palm is a cultivar. Cultivars are not eligible for
protection under the Act. Speaking to this distinction, there has been
much litigation on the subject of the intent of the relative ambiguity
of the term ``species'' in the Act. In Trout Unlimited v. Lohn (559 F.
3d 946 9th Cir. 2009), the 9th Circuit Court of Appeals found that
``the [Act's] primary goal is to preserve the ability of natural
populations to survive in the wild.'' The Act (16 U.S.C. 1531(b))
states''[t]he purposes of this [Act] are to provide a means whereby the
ecosystems upon which endangered species and threatened species depend
may be conserved, [and] to provide a program for the conservation of
such endangered species and threatened species * * *.'' Regarding this
provision, the court found ``[t]hat the purpose of the [Act] is to
promote populations that are self-sustaining without human interference
can be deduced from the statute's emphasis on the protection and
preservation of the habitats of endangered and threatened species.''
The court also points to the use in the statute of the term
[artificial] propagation as merely a means ``to bring any endangered
species or threatened species to the point at which the measures
provided pursuant to this [Act] are no longer necessary'' (16 U.S.C.
1532(3)). Trout Unlimited v. Lohn, therefore, interprets the Act as a
statutory means to protect animal and plant resources that are natural
and self-sustaining. The sphinx date palm, as a cultivar whose
propagation depends fully on human intervention, does not meet these
criteria.
The Act defines a species as including ``any subspecies of fish or
wildlife or plants, and any distinct population segment of any species
of vertebrate fish or wildlife which interbreeds when mature'' (16
U.S.C. 1532 (16)). The Service considers plant varieties and subspecies
to be essentially identical (``Determination that 11 Plant Taxa are
Endangered Species and 2 Plant Taxa are Threatened Species'', 43 FR
17910). Cultivar is a taxonomic level below that of subspecies and
variety, and, therefore, cultivars are not listable entities as defined
in the Act.
We conclude that the sphinx date palm is not a listable entity as
defined under the Act. Therefore, after a review of the guiding
regulations, we conclude that the petitioned entity does not constitute
a ``listable entity'' and cannot be listed under the Act.
The District Court in the District of Oregon in their determination
for Alsea Valley Alliance v. Evans (161 F. Supp. 2d 1154 D. Ore.),
referenced cases in which it was found that ``[l]isting distinctions
below that of subspecies or a DPS of a species are not allowed under
the [Act]'' (Southwest Center, 980 F. Supp at 1085). The court noted
that the ``term `distinct population segment' was amended in the [Act]
in 1978 so that it would `exclude taxonomic [biological] categories
below subspecies [smaller taxa] from the definition'' (H.R. CONF. REP.
No. 95-1804, at 17 (1978) reprinted in 1978 U.S.C.C.A.N. 9485, 14855).
Under the definition in the Act, and as analyzed above, the sphinx date
palm does not meet the criteria for species or subspecies.
We conclude that the sphinx date palm is not a valid taxonomic
entity and does not meet the definition of a species or a subspecies
under the Act. Therefore, after a review of the guiding regulations and
litigated precedents, we conclude that the petitioned entity does not
constitute a ``listable entity'' and cannot be listed under the Act.
Finding
In summary, the petition does not present substantial information
indicating that listing the Sphinx date palm as endangered is
warranted, because the entity as petitioned is not listable under the
Act.
