GLOBAL ANALYSIS FINDS NEARLY HALF THE EARTH IS
STILL WILDERNESS
Many areas, including North
America’s deserts, under severe threat
According to the most comprehensive global
analysis ever conducted, wilderness areas still cover close to half the Earth's
land, but contain only a tiny percentage of the world's population. More than
200 international scientists contributed to the analysis, which will be
published in the book, Wilderness: Earth's Last Wild Places, (University of
Chicago Press, 2003).
The 37 wilderness areas identified in the book
represent 46 percent of the Earth's land surface, but are occupied by just 2.4
percent of the world's population, excluding urban centers. Nine of the
wilderness areas fall, at least in part, within the United States.
Although the wilderness areas are still largely
intact, they are increasingly threatened by population growth, encroaching
agriculture and resource extraction activities. Barely 7 percent of the areas
currently enjoy some form of protection.
Nineteen of the wilderness areas have remarkably
low population densities – an average of less than one person per square
kilometer. Excluding urban centers, these 19 areas represent 38 percent of the
Earth's land surface, but hold only 0.7 percent of the planet's population.
"These very low density areas represent a
landmass equivalent to the six largest countries on Earth combined – Russia,
Canada, China, the United States, Brazil and Australia – but have within them
the population of only three large cities, a truly remarkable finding,"
said co-author Russell Mittermeier, President of Conservation International.
"It's good news that we still have these large tracts of land largely
intact and uninhabited, but these areas are increasingly under threat."
The large-format, 576-page book depicts rare
species and remarkable places in more than 500 breathtaking color photographs
that accompany detailed information regarding the habitat, species and cultural
diversity of each wilderness area. The analysis was mainly carried out over the
past two years by Conservation International's Center for Applied Biodiversity
Science with support from the Global Conservation Fund.
The wilderness areas include several diverse
habitats, ranging from Southern Africa's Miombo-Mopane Woodlands, with the
world's largest remaining population of African elephants, to the Sonoran and
Baja Californian Deserts of Arizona, California and Mexico, with their Gila
woodpeckers and giant cacti, to Amazonia's rainforests, teeming with
biodiversity including 30,000 endemic plant species and 122 endemic primate
species and subspecies.
To qualify as "wilderness," an area has
70 percent or more of its original vegetation intact, covers at least 10,000
square kilometers (3,861 square miles) and most have fewer than five people per
square kilometer.
"Wilderness areas are major storehouses of
biodiversity, but just as importantly, they provide critical ecosystem services
to the planet, including watershed maintenance, pollination and carbon
sequestration," said Gustavo Fonseca, Executive Director of CI's Center for
Applied Biodiversity Science. "As international debates on climate change
and water security continue, these wilderness areas take on even greater
importance."
Only five wilderness areas are considered "high-biodiversity
wilderness areas," because they contain at least 1,500 endemic vascular
plant species, meaning they are found nowhere else in the world. The five areas
are Amazonia, the Congo Forests of Central Africa, New Guinea, the North
American Deserts and the Miombo-Mopane Woodlands and Grasslands of Southern
Africa.
"These wilderness areas are important for
any global strategy of protecting biodiversity, since we have the opportunity to
save large tracts of land at relatively low costs," said Peter Seligmann,
CI's Chairman and CEO. "The areas are also critical for Earth's remaining
indigenous groups, which often want to protect their traditional ways of life
from the unwanted by-products of modern society."
"As striking as these wilderness numbers are,
they only serve to underscore more than ever the critical importance of
protecting the biodiversity hotspots, areas which represent only 1.4 percent of
the Earth's landmass but contain more than 60 percent of its terrestrial species,"
said Mittermeier. "If we are to succeed as conservationists, we have to
take a two-pronged approach of protecting the biodiversity hotspots and
high-biodiversity wilderness areas simultaneously."
The book is the result of collaboration between
Conservation International and Agrupación Sierra Madre, and is published
by CEMEX, a Mexican company that also published the first two books in this
series, Megadiversity and Hotspots.
Wilderness: Earth's Last Wild Places is now
available through Conservation International (http://www.conservation.org/).
The University of Chicago Press will accept pre-orders beginning in December (http://www.press.uchicago.edu/),
and the book will be available in bookstores in Spring, 2003.

Conservation International (CI) applies
innovations in science, economics, policy and community participation to protect
the Earth's richest regions of plant and animal diversity in the hotspots, major
tropical wilderness areas and key marine ecosystems. With headquarters in
Washington, D.C., CI works in more than 30 countries on four continents. For
