dry season on the southwestern coast of Vietnam is crane-counting time. Near a
small village on its border with Cambodia, wildlife ecologists from the
International Crane Foundation in Wisconsin and researchers from Ho Chi Minh
City stake out the ponds and marshes where the Eastern Saurus cranes gather to
feed. Reporter Gil Halsted joined them, and learned that tracking the crane
population in Vietnam and protecting their habitat is a joint effort.
Just at dusk, a flock of cranes flies in from the east, calling to each
other. The big birds' silhouettes are clear against a gray sky dominated by the
belching smokestacks of a huge concrete factory. They land in the shallows of a
small pond where they will roost tonight, and cool off. Researchers count about
30 birds in the flock.
cranes seem oblivious to the blasting going on in the nearby hills. The noise
won't end until the sun is finally down and it's too dark for the concrete
factory workers to blast out any more limestone.
The next morning, binoculars in hand, Tran Triet leads a small group on a
bird watching expedition to the 2000 hectares of uninterrupted green wetlands
that makes up the International Crane Foundation's sanctuary. As the crane
flies, it's about three kilometers from the pond where the flock roosts at
night. Four or five of the stately birds with their red crested heads and long
gangly legs are feeding in the wetland. Triet, chief ecologist for the Crane
Foundation projects in Vietnam, says it's a family group.
farming poses threat
A raised dirt road separates the sanctuary from a canal that runs along the
border of the neighboring industrial shrimp farm. Ponds stretch to the horizon,
almost to the coast. They are dotted with pumps that aerate the water and locks
that mix the salt and fresh water to the ideal blend for shrimp growth.
motorboat buzzes by on the canal, Triet says the development pressures here are
the same as they are near the concrete factory where the cranes roost.
"Cranes will not come here if, y'know, too many people travel on this road
and this canal," he explains. "They will abandon this."
It's not just the boat traffic that threatens the cranes, it's the shrimp
farms themselves that are the greater threat. The brackish water in the ponds
degrades the fresh water wetlands as the salt leeches into the soil. When the
shrimp farms fail because of disease or drought – which they often do – Triet
says the land is ruined for the cranes, as well as for rice cultivation. He
says restoring it to wetland is almost impossible.
threat makes protecting the Foundation's wetland sanctuary even more crucial.
This year's crane count found less than 200 birds feeding here, compared to
more than a thousand counted eight years ago.
common ground for people and cranes
In an effort to keep the population from shrinking more, Triet and his
students set up a conservation project with the village of Phu My, close to the
sanctuary. The villagers harvest lepironia from the wetlands. They use the
plant's long grey-green stems to make mats for drying and winnowing their rice.
Tran Triet says lepironia grows side by side with another species of grass that
provides the main food source for the Eastern Saurus cranes. "So if we
manage the harvesting of lepironia well, then there will be no conflict of
crane use of the same area."
Inside a small building with white washed walls about 20 women work at
sewing machines and large looms strung with twisted strands of lepironia grass.
They're weaving straw mats and tote bags to sell in handicraft shops in Europe
and the United States. Their work for the Phu My Lepironia Grassland
Conservation Project nets them almost $2 a day. That's triple what they were
making as rice farmers before the project began.
marriage of interests – between cranes and the humans they share the land with
– is the same approach the Crane Foundation uses in Wisconsin, where it's
headquartered. Sitting in his office, wetland ecologist Jeb Barzen points to a
map with potato fields marked on it and explains the strategy the Foundation
has used to convince farmers to use non-toxic pesticides and preserve some of
their land for sandhill cranes to feed on. In return, the farmers place a World Wildlife
Fund label on their potatoes, which allows them to charge a premium for being
But Barzen says the farmers also get the satisfaction of knowing they are
managing their land responsibly. "It's trying to create an alternative to
help compete within this economic system that we have that actually includes
these environmental issues. So it's the same thing, but it's in a Wisconsin
figures in cultural symbolism
sandhill cranes in Wisconsin have an important cultural significance and a
special place in people's imagination, just as the Saurus cranes do in Asia.
"Cranes are a fascinating animal and basically most cultures and most
people look at them and say they're cool, and that gives people who are foreign
to each other something in common," Barzen says, adding that's what makes
it possible for this cooperative wildlife conservation model to protect the
birds whether they live in Wisconsin or in Vietnam.
before European potato farmers settled in Wisconsin, the crane played an
important role in the life and beliefs of Native Americans here. Almost all the
chiefs of the Ojibwe tribe belonged to the crane clan.
And the stately bird is also an important cultural symbol in Asia,
according to wetland ecologist Tran Triet. "You see crane pictures [on]
very old pieces of art. If you go to the Bayon Temple in Angkor, you see crane
sculptures carved on the wall of the temple. That was in the 12th century. And
if you go to pagoda or temples in Vietnam you see statues of cranes, symbol of
if the Crane Foundation is successful in Phu My, the real life models for those
sculptures will continue to be a part of the changing ecology and landscape of
both Wisconsin and Vietnam.
