**ADDENDUM TO APPLICATION FOR INCLUSION OF A PROPERTY IN THE U.S. WORLD
HERITAGE TENTATIVE LIST**

27 June 2005

**B. Owner Concurrence:**

Are all the property owners aware of this proposal for the inclusion of
the property in the U.S. Tentative List and do all of the property
owners agree that it should be considered? If any agreement is uncertain
or tentative, or if the ownership situation is disputed, otherwise
complicated, or unclear, please explain the issues briefly.

YES: \_\_\_[x]{.underline}\_\_\_\_\_ NO: \_\_\_\_\_\_\_\_

Comment: [The Petrified Forest National Park Expansion Act of 2004
allows for the park to obtain an additional 50,586 hectares (125,000
acres) adjacent to the park to protect significant cultural and natural
resources. The acquisition of these properties by the NPS is ongoing and
anticipated to take years to complete. Therefore these additional
properties are not being considered for inclusion ~~at this time~~. This
will not affect the significance of the site as the existing 37,852
hectares (93,533) acres have been protected by the NPS in part since
1906 and in their entirety since 1932. These 37,852 hectares (93,533
acres) contain the key resources that define the significance of the
site and make it eligible for inscription. When acquired the expansion
areas will serve as a buffer zone for the site. In particular the buffer
zone will provide for protection of the large accumulations of petrified
wood in remote backcountry and wilderness areas.]{.underline}

~~[If the expansion properties are added to the park before the park is
nominated for World Heritage Status it would be desirable to also
include this acreage as it does contain globally significant
paleontological resources. If necessary, this modification would be made
during the nomination process.]{.underline}~~

**D. Scheduling:**

If you wish a property to be nominated to the World Heritage List in a
particular year during the period 2009-2019, please indicate the
reason(s) why and the earliest year in which you feel it will be
possible to meet all requirements for nomination*. (Please review this
entire **Questionnaire** before finally answering this question.)*

Preferred Year:
\_[2009\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_]{.underline}\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

Reasons: ~~[This would allow time for the park to obtain expansion
properties and include them for World Heritage Status. At the present
these properties are being excluded; however, acquisition attempts are
ongoing and it is very possible that some if not all of this property
will be obtained by 2019.]{.underline} [These properties also contain
significant paleontological resources that meet criterion viii.
However,]{.underline}~~ [The 37,852 hectares (93, 533 acres) that are
currently proposed meet all of the requirements for nomination,
including management and protection, and is prepared for a nomination as
early as 2009.]{.underline}

**1.d.-e. Location, boundaries, and key features of the nominated
property**

Include with this **Application** sketch maps or other small maps,
preferably letter-size, that show:

\- the location of the property

\- the boundaries of any zones of special legal protection

\- the position of major natural features and/or individual buildings
and structures

\- any open spaces (squares, plazas) and other major spatial
relationships (the space between buildings may at times be more
important than the buildings)

Please provide here a list of the maps that you have included.

[Three maps showing the locations of Arizona, Petrified Forest National
Park including the proposed area for listing including the Painted
Desert Wilderness area. The third map also shows the largest petrified
wood accumulations ("forests").]{.underline}

**2.a. Description of the Property**

###### Natural property

Briefly describe the property and list its major components. A summary
in a few paragraphs or pages is all that is required.

**(fifth paragraph -- 1^st^ sentence)**

[Currently there are thirteen species of petrified wood recognized from
the park with the potential for dozens more.]{.underline}

**(sixth paragraph -- 1^st^ sentence)**

[Fossil leaves, stems, seeds, cones, and pollen are also preserved in
abundance. Currently over 200 species of fossil plants have been
described from the park, including 60 holotypes (specimens on which new
species are based).]{.underline}

**2.b. History and Development of the Property**

**Natural property**

**(third paragraph)**

[The main threat posed by park visitors is the illegal collection of
petrified wood. This has been a problem since before the park was
established and is countered by educational messages, regular patrols of
the major wood deposits, the use of remote sensing equipment, and stiff
fines for violators. Determining the amount of wood removed each year is
an impossible task; however, previous studies that put the amount at
10.8 metric tons (12 U. S. tons) per year are certainly inflated. More
recent studies, including the use of repeat photography, show very
little change in the wood deposits due to visitor interaction and the
sites that are affected are limited to just a couple of small areas
close to trails and roads. The majority of the wood deposits ~~are
seldom seen by visitors and~~ are largely unimpacted by visitor
activity. On the attached map (map #3) the grey areas show the locations
of the largest accumulations of wood in the park. The locations of
trails that are open to the public are shown and the areas in red denote
areas that have the strongest potential to be impacted by visitors due
to proximity to these trails. Almost all of the petrified wood theft in
the park consists of casual collecting of small pieces by visitors along
these trails. Since 2001 only a single case of attempted commercial
theft has occurred along the park boundary and the responsible
individuals were apprehended due to the placement of remote sensors at
this site.]{.underline}

**2.c. Boundary Selection**

**[(second paragraph)]{.underline}**

[The Petrified Forest Expansion Act of December of 2004 authorized the
park to obtain 50,586 hectares (125,000 acres) of additional lands
adjacent to the park. Acquisition of these lands ~~has been initiated
and~~ is ongoing; however, these lands are not included in this
application. The expansion areas were added for their potential for
~~richness of~~ paleontological and archaeological resources; however,
they lack sizeable accumulations of petrified wood and have not been
surveyed for other types of fossils. Furthermore the expansion areas
have been impacted by years of private use, including ranching, and much
land restoration will be required. Conversely, the proposed World
Heritage Site property has been protected since 1932 and contains all of
the significant natural resources and outstanding universal value that
qualify the property for inclusion. Therefore, the expansion areas are
considered a buffer zone for the proposed World Heritage Site property.
~~If these lands are added prior to the nomination process they should
be seriously be considered for inclusion due to the outstanding
universal value of their paleontological resources. These resources also
include extensive areas of petrified wood as well as fossil vertebrate,
invertebrate, and plant fossil sites. Past researchers who have sampled
these areas noted that the fossil deposits in these areas rival those
found within the existing park boundary.~~]{.underline}

**3.c. Comparison of proposed property to similar or related properties
(including state of preservation of similar properties)**

**(Section 2 --second paragraph)**

[Worldwide, Late Triassic rocks are exposed on every continent; however,
only the Triassic of Argentina rivals that of the southwestern United
States in the amount of outcrop exposure and vertebrate fossil
diversity. Ischigualasto Provincial Park was inscribed on the World
Heritage List in 1979 based on its Triassic geology and paleontology.
While notable because it preserves well-exposed strata from much of the
Triassic, recent research suggests that there are windows of Triassic
time not preserved in Ischigualasto, one of which is the section of Late
Triassic time that is preserved at Petrified Forest National Park.
Researchers have divided the Late Triassic into four distinct time
intervals (biochrons) based on the terrestrial fossil fauna. From oldest
to youngest these are the Ischigualastian (type fauna is from
Ischigualasto Provincial Park), the Adamanian (type fauna is from
Petrified Forest National Park), the Revueltian, and the Apachean. The
two major vertebrate faunas of Ischigualasto Provincial Park are
Ischigualastian and Apachean in age, whereas the three distinct faunas
of Petrified Forest National Park are Adamanian and Revueltian (see
attached faunal comparison chart). Thus, although they overlap in time,
the two sites do not preserve the same faunas, and therefore do not
compete but instead clearly compliment each other.]{.underline}

[Although Ischigualasto preserves a miscellaneous fauna and flora, they
are not as diverse or well-documented as those of the Petrified Forest.
The floras are also significantly different; that of Ischigualasto is
dominated by the fern-like foliage *Dicroidium*, whereas the Petrified
Forest flora lacks *Dicroidium* and is instead dominated by conifers.
Furthermore, Ischigualasto lacks the extensive petrified wood deposits
found at Petrified Forest National Park.]{.underline}

[Finally, Ischigualasto is known for its early dinosaur fossils, and
until recently provided the best record of early dinosaurs in the world.
However, recent discoveries from the Chinle Formation, including
Petrified Forest National Park, are providing an early dinosaur record
that rivals, if not surpasses, that of Ischigualasto.]{.underline}

[(add a section 3)]{.underline}

[3) The Painted Desert is one of the most recognized and scenic areas in
North America.]{.underline}

[When most people think of scenic beauty they usually conjure images of
mountains and trees, waterfalls and rushing river. The Painted Desert,
which contains none of these familiar resources, can be quite an
otherworldly shock. First noted by military expeditions in the 1850s the
Painted Desert is famed for its barrenness, which exposes the vivid
colors of the underlying rock. The landscape, characterized by badland
hills and mesas, appears to have no limit, stretching on for ever. The
shades of colors of these badlands vary continuously as the interplay of
sun and shadow change throughout the day. Because of these features the
Painted Desert is extremely popular with photographers, photographic
magazines such as "Arizona Highways", and artists including Thomas
Moran, who is recognized as one of America's premier landscape artists.
The legendary author Zane Grey was mesmerized by a trip through the
Painted Desert and subsequently settled in the area to write his
numerous fictional works on the cowboys of the American southwest. His
beloved Painted Desert is featured prominently in his first novel
'Heritage of the Desert' published in 1910. The Painted Desert has also
been featured in two well-known movies, 'The Grapes of Wrath' (1940)
based on the famous John Steinbeck novel, and 'The Painted Desert'
(1931) which is recognized as featuring Clark Gable's first significant
acting role.]{.underline}
