Dr. Brian Lockhart

Dr. Brian Lockhart, a forest researcher with the U.S. Forest Service, will discuss the meanderings of the Mississippi, Arkansas and Ohio rivers in the Mississippi Alluvial Valley over the past 6,000 years at the May 3 meeting of the Tunican Chapter of Arkansas Archeological Society.

Lockhart, who has degrees from the University of Arkansas at Monticello, Yale University, and Mississippi State University, will discuss the changing location of these rivers, how changes in river flow have influenced humans, how humans have influenced river flow, and the importance of this information for forest resources management.

The rivers of the Mississippi Alluvial Valley have meandered across the floodplain since glacial retreat following the last ice age. At different points in time, each of these major rivers was the primary river flowing to the Gulf of Mexico. Humans were present in the Mississippi Alluvial Valley since the last glacial retreat; therefore, meandering rivers played a major role in the location of humans in their travel and trade. Meandering rivers also have specific sedimentation patterns that lead to contrasting site conditions that affect tree species composition and structure.

Lockhart’s program titled, Meandering Rivers in the Mississippi Alluvial Valley: Influence on Human Settlement & Forest Resources Management, will be held on May 3 at 6:30 p.m. in the School of Forestry and Natural Resources conference room on the UAM campus.

The event is free and open to the public. Teachers attending the event can receive continuing education credit.

The Tunican Chapter of the Arkansas Archeological Society is a group of people interested in the archeology and history of Arkansas. Members work with the UAM Research Station of the Arkansas Archeological Survey to document and preserve Arkansas’s cultural heritage and to foster and encourage interest in the preservation of sites and artifacts. The Chapter holds a monthly speaker series on the first Tuesday of each month.
