Logging 'caused Nazca collapse'

By Jody Bourton
Earth News reporter



The ancient Nazca people of Peru are famous for the lines they drew in the desert depicting strange animal forms.

A further mystery is what happened to this once great civilisation, which suddenly vanished 1,500 years ago.

Now a team of archaeologists have found the demise of the Nazca society was linked in part to the fate of a tree.

Analysing plant remains they reveal how the destruction of forests containing the huarango tree crossed a tipping point,
causing ecological collapse.

The team have published their findings in the journal of Latin American Antiquity.

"These were very special forests," says Dr David Beresford-Jones from the McDonald Institute for Archaeological
Research, University of Cambridge, UK who led the team.

The huarango tree (Prosopis pallida) is a unique tree with many qualities and played a vital role in the habitat,
protecting the fragile desert ecosystem, the scientists say.

"It is the ecological keystone species in the desert zone enhancing soil fertility and moisture and underpinning the floodplain
with one of the deepest root systems of any tree known," Dr Beresford-Jones says.

The tree was also a useful resource.

"This remarkable nitrogen-fixing tree was an important source of food, forage timber and fuel for the local people."

Researchers have previously found evidence that suggests the disappearance of the Nazca society was a due to
catastrophic flooding event as a result of El Nino around 500 AD.

El Nino is a cyclical event that occurs as a result of a change in ocean temperatures that can cause a change in
climate and severe flooding to the the west coast of South America.

The researchers have now found new evidence that suggests the society would not have been so easily destroyed if they
had not cut down the forests around them.

Analysing plant remains and pollen in soil 1.5m deep, the team was able to trace an important sequence of events which
show the clearing of woodland for agriculture.

"At the bottom of the profile there is a lot of huarango pollen and little evidence of human impact," explains Dr Alex
Chepstow-Lusty from the French Institute of Andean Studies in Lima, Peru who also took part in the study.

"Then, at 80cm deep, maize pollen becomes common, showing the importance of this crop, suggesting a greater need for
food and an increasing population," he says.

"It is now we notice a big impact on the huarangos and a major decrease in their pollen."

"Then suddenly corresponding with the El Nino event at AD 500 or shortly afterwards, the pollen is dominated by
weeds in the family Chenopodiaceae, which are adapted to salty conditions and this landscape is now the desert seen
today."

The Nazca are famous for creating complex line drawings that can only be seen from the air in the Nazca desert, Peru
400km south of Lima.

They were created between 500BC and 500AD and depict animals such as monkeys and whales as well as
geometric figures several kilometres long.

As well as the lines, the Nazca also formed a sophisticated society, constructing complex irrigation systems for agriculture.

However, despite their skills and expertise, the researchers say the Nazca society inadvertently contributed to their own
demise through the removal of the tree species.

"The landscape only became exposed to the catastrophic effects of that El Nino flood, once people had inadvertently
crossed an ecological threshold," explains Dr Beresford-Jones.

"Such thresholds or 'tipping-points' are sharply defined in these desert environments."

"Our research contradicts the popular view that Native American peoples always lived in harmony with their environment
until the Spanish Conquest," Dr Beresford-Jones says.

Dr Beresford-Jones explains that with sufficient huarango cover, El Nino's were in fact not great disasters and actually
created years of abundance replenishing water aquifers.

Once too much clearance had occurred the landscape was exposed to the effects of the El Nino floods.

"The river down cut into its floodplain and that floodplain narrowed hugely, irrigation systems were left high and
dry," he says.

"Human induced gradual change is just as important to the full story of Nazca collapse as the major climatic impacts
that eventually precipitated them."

Pilot Reports New Nazca Lines Discovery
AUGUST 4, 2014

Strong sand storms have revealed a number of new geoglyphs in the Nazca desert that experts say most probably belong to the Paracas culture (400 BC -200 AD), daily Peru.21 reported.

The desert plains of Nazca are already well-known for large drawings etched into the ground that include a monkey, spider, hummingbird and other figures that became famous with the studies and conservation work by German mathematician Maria Reiche.

The new site, which includes the drawing of a snake, were reportedly discovered by a pilot who was flying over the El Ingenio valley, located in southern Peru’s Ica region.

“They are enigmatic drawings that would be more than 2,000 years old,” the pilot and researcher, Eduardo Herran, said.

According to Italian archaeologist Giuseppe Orefici, who has worked in the Nazca and Palpa areas since 1977 and is director of the Antonini Museum in Nazca, the new finds include the drawing of a serpent, a bird with open wings and a very short tail, and a clear zigzag outline next to another bird drawing of which only the claws and lower part of the body are now visible.
Ruben Garcia, the director of archaeological heritage at Ica’s Culture Office, called the discovery a “valuable contribution to the knowledge of the ancient Nazca people.”

In late 2012, archaeologists from Bristol University discovered a three circuit labyrinth, four kilometers in size, which is believed to have been drawn some 2000 years ago.

A year earlier, a multidisciplinary team headed by archaeologist Masato Sakai of Yamagata University, Japan, and co-director Jorge Olano found a series of lines leading to 138 circular mounds, as well as two animal figures.

Interesting how agriculture and land clearing ultimately did in a lot of ancient civilizations. Sumerian and biblical texts both have agricultural tips embedded in them. Like leaving the ground fallow one year out of every seven so nutrients can be restored.

Truck damages Peru's ancient Nazca lines
Jan.30, 2018

This Peruvian Ministry of Culture picture shows damage caused by a truck that illegally entered the archaeological site where the ancient Nazca lines are located on January 27.


Peru's ancient Nazca lines were damaged when a driver accidentally plowed his cargo truck into the fragile archaeological site in the desert, officials said Tuesday.

The lines, considered a UNESCO World Heritage site, are enormous drawings of animals and plants etched in the ground some 2,000 years ago by a pre-Inca civilization. They are best seen from the sky.

The driver ignored warning signs as he entered the Nazca archaeological zone on January 27, the Ministry of Culture said in a statement.

The truck "left deep prints in an area approximately 100 meters long," damaging "parts of three straight lined geoglyphs," the statement read.

Security guards detained the driver and filed charges against him at the local police station, the statement added.

Entering the area is strictly prohibited due to the fragility of the soil around the lines, and access is only allowed wearing special foam-covered foot gear, according to Peruvian authorities.

The lines criss-cross the Peruvian desert over more than 500 square kilometers (200 square miles).

Created between 500 BC and AD 500 by the Nazca people, they have long intrigued archaeologists with the mystery of their size and their meticulously drawn figures.

Some of the drawings depict living creatures, others stylized plants or fantastical beings, others geometric figures that stretch for kilometers (miles).

This is not the first time the Nazca lines have been damaged in recent years.

In September 2015 a man was detained after he entered the site and wrote his name on one of the geoglyphs.

In December 2014, Greenpeace activists set up large letters beside one of the designs, known as the Hummingbird, that read: "Time for change! The future is renewable."

The protest drew a furious reaction from Peru, which at the time was hosting UN talks aimed at curbing global warming.

Worse yet are the people who just want to destroy anything beautiful and unique because they can.
