Wetlands Preservation Also Preserves Archeology

A large wetland restoration project in the Midwest is expected to bring back a variety of native
plants and animals. But in addition to the environmental benefits, the project is helping out an
unexpected group – archeologists. The Great Lakes Radio Consortium’s Jonathan Ahl reports:


Alan Harn is standing on the top of a ridge overlooking a seven thousand-acre farm in Central
Illinois. Harn is the assistant curator of Archeology at the Dickson Mounds Museum in nearby
Lewistown. While he has surveyed just about all of the land in the region for archeological sites
over his forty-year career, he only recently was able to get into these bottomlands next to the
Illinois River:


“Even though I’ve walked over that land for most of my lifetime I was never forced to know it.
But we found 55 new archeological sites. And these sites have been found in areas that, had I not
been forced to look at them, I would have overlooked them.”


Harn says during his short window of opportunity to search the land, he found temporary
campsites of the Mississippian and Oneota Indians from about 900 to 1200 A-D. The discoveries
are part of a unique partnership between environmentalists and archeologists. The Nature
Conservancy purchased this land to convert it to a wetland. But before they bring back native
plants and animals to the region, they are letting archeologists survey the property. Larry Conrad
is director emeritus of the Western Illinois University Archeological Research Lab. He says
farming has done significant damage to many Native American sites in the Midwest:


“They were plowing a lot of the sites, particularly those in the bottoms, and this gradually
deteriorated the sites. And there was collecting by at least workmen. They used to bring axes
and spearheads off those sites without any documentation.”


Conrad says environmentalists may be the best hope archeologists have to protect important
pieces of land that have not yet been surveyed. He says conservation groups are one of the few
private property owners that do not abuse the land they own:


“Unfortunately, a lot of people view it as the property belongs to them and they can do whatever
they want, and if there are archeological resources, some people are irresponsible or destructive
toward the resources. We look forward to the Nature Conservancy as being an excellent steward
and they own a very large tract of land there now. So it’s a tract of land we don’t have to worry
about.”


Conrad says even after the survey of the land is over, any sites not found will be underneath water
and vegetation –not at risk of being plowed and damaged. The Nature Conservancy is happy
another group of people is benefiting from their plans to restore this piece of land. Doug Blodgett
is with the Nature Conservancy and is heading up the restoration effort. He says in this project,
the archeological element is a natural fit:


“The archeology is such an important issue here. It’s important to us because it fits right in with
our mission. It’s almost a part of our mission. It helps better explain and justify our mission.
The reason native Americans were here for twelve thousand years is because of the abundant
natural resources that were there in the flood plain. So it just enhances our story.”


But Blodgett says the Nature Conservancy’s mission is to create bio-diversity, and not protect
archeological sites. He says if digging for artifacts ever gets in the way of protecting plants and
animals, they will not hesitate to call off the archeologists. Alan Harn realizes that could be a
possibility. He says that’s why they will continue to survey this land while they have the chance
before the restoration begins:


“We have no idea what lies out there. I think that’s the fun thing about archeology is that every
time you answer a set of questions, it opens a door, and in that door is a room full of new
questions that you didn’t even know existed. We will be continuing the search for the record.”


Harn still has some time to continue his search. The Nature Conservancy is planning to begin its
restoration plan in earnest at the end of next year.
