O Parque Nacional de
Yellowstone, criado em 1872, é constituído por uma vasta floresta que cobre cerca
de 9.000 km2, dos quais 96% no estado de Wyoming, 3% no de Montana e
1% no de Idaho.
Nele se encontra a quase
metade dos fenómenos geotérmicos do planeta, com cerca de 10.000 exemplos
diferentes. O Parque apresenta a maior concentração mundial de geysers, mais de
3.000, que constituem cerca de 2/3 dos geysers do planeta. O Parque é
igualmente conhecido pela sua fauna selvagem, que inclui ursos grizzly, lobos,
bisontes e wapitis.

La vaste forêt naturelle du parc national de Yellowstone couvre près de
9 000 km2 , dont 96 % dans le
Wyoming, 3 % dans le Montana et 1% dans l'Idaho. On trouve à Yellowstone plus
de 10 000 caractéristiques thermales, soit plus de la moitié des phénomènes
géothermiques du monde. Le parc possède également la plus forte concentration
mondiale de geysers, 300 environ qui représentent les 2/3 des geysers de la
planète. Créé en 1872, le parc est également connu pour sa faune sauvage qui
comprend l'ours grizzli, le loup, le bison et le wapiti.

The vast natural forest of Yellowstone National Park covers nearly 9,000
km2 ; 96% of the park lies
in Wyoming, 3% in Montana and 1% in Idaho. Yellowstone contains half of all the
world's known geothermal features, with more than 10,000 examples. It also has
the world's largest concentration of geysers (more than 300 geyers, or two thirds
of all those on the planet). Established in 1872, Yellowstone is equally known
for its wildlife, such as grizzly bears, wolves, bison and wapitis.
Statement of Significance
Criterion (vii): The extraordinary scenic treasures of Yellowstone include the world’s
largest collection of geysers, the Grand Canyon of the Yellowstone River,
numerous waterfalls, and great herds of wildlife.
Criterion (viii): Yellowstone is one of the world's foremost sites for the study and
appreciation of the evolutionary history of the earth. The park has a globally
unparalleled assemblage of surficial geothermal activity, thousands of hot
springs, mudpots and fumaroles, and more than half of the world’s active
geysers. Nearly 150 species of fossil plants, ranging from small ferns and
rushes up to large Sequoia and many other tree species, have been identified in
the park’s abundant fossil deposits. The world’s largest recognized caldera
(45km by 75km – 27 miles by 45 miles) is contained within the park.
Criterion (ix): The park is one of the few remaining intact large ecosystems in the
northern temperate zone of the earth. All flora in the park are allowed to
progress through natural succession with no direct management being practiced. Forest
fires, if started from lightning, are often allowed to burn where possible to
permit the natural effects of fire to periodically assert itself. The park’s
bison are the only wild, continuously free-ranging bison remaining of herds
that once covered the Great Plains and, along with other park wildlife, are one
of the greatest attractions.
Criterion (x): Yellowstone National Park has become one of North America's foremost
refuges for rare plant and animal species and also functions as a model for
ecosystem processes. The grizzly bear is one of the worlds’ most intensively
studied and best-understood bear populations. This research has led to a
greater understanding of the interdependence of ecosystem relationships.
Protection of the park’s flora and fauna, as well as the natural processes that
affect their population and distribution allow biological evolution to proceed
with minimal influence by man.
