John Pearson, Iowa Department of Natural Resources, will present "Perspectives of Iowa Savannas for Restoring a Pre-Settlement Landscape." Savanna was a major plant community of early Iowa occupying more than 2.4 million acres. Types of savanna differed ranging from park-like areas with widely distributed tress interspersed with prairie vegetation and virtually no shrub layer to dense thickets of woody species within a prairie matrix with a few stunted open growth trees. Oak savanna is regarded as a high priority for conservation because no original savanna currently exists. Interest in savanna restoration is increasing, but selecting sites to restore is influenced by variety of definitions and concepts. Pearson will explore contrasting concepts in savanna posed by historic maps, modern soil surveys and floristics, and relate them to the use of 1832-1859 General Land Office surveys, Mollic Hapludalf soil maps and plant indicator species in restoration. Refreshments will be provided.

Dr. E. Arthur "Art" Bettis of the University of Iowa's Department of Geoscience will outline the processes that formed the landscape of the Mississippi River valley during the last glacial period and over the past 10,000 years. Bettis will also discuss why bottomland restoration scenarios should incorporate existing information about the valley’s geomorphology to develop cost-effective projects and best management practices.

His teaching and research focus on landscape evolution during the past 2 million years. He pursues interests in the long-term behavior of eolian, fluvial and glacial systems and the impact of human activities on the landscape. His recent research involves the Homo erectus peopling and occupation of island Southeast Asia, stratigraphic and sedimentological studies of Midcontinet U.S. loess depositional systems, and the application of alluvial lithostratigraphy in stream management and restoration.

Molly Schlumbohm, a graduate student at the Tallgrass Prairie Center, will present "Maximizing Biomass Production of Prairie Vegetation as an Alternative Energy Source."  Schlumbohm studied four treatments to determine the best mixture of prairie vegetation to maximize the production of biomass on marginal farmland.  This biomass can be used as an alternative energy source to coal. Refreshments will be provided.

Carl Kurtz will discuss his native seed production process including seasonal management of the production site, harvesting method, machinery required, yield in pounds/acre and species diversity, bagging process, seed analysis and marketing strategy. Kurtz is a multi-talented naturalist and farmer who does freelance writing, photography, teaching, lecturing, tallgrass prairie reconstruction and produces native prairie seed. He is probably best known for his photography with photos appearing nationwide in more than 50 publications and is the author of Iowa’s Wild Places and A Practical Guide to Prairie Reconstruction.

Dr. Rick Lampe, professor of biology at Buena Vista University, will present "Student Field Trips to South Africa: Optimal Learning Experiences in an Exotic Environment," a composite discussion of historical, cultural and biological education gained from multiple field trips with Buena Vista students to South Africa. Student field trip participants have opportunities to experience the rich history and culture of South Africa as well as observing and studying the unique ecosystems and wildlife of that portion of the exotic African continent. Refreshments will be provided.

The Tallgrass Prairie Center will hold an open house to showcase the new renovation and building expansion.  The Center is located on the western edge of campus, at 2412 W. 27th St., west of Hudson Road.  This event is free and open to the public.  Refreshments will be served.

The presentation "Geologic History of the Upper Mississippi River Valley and Bottomland Restoration Scenarios" by Art Bettis will be rescheduled.  Daryl Smith, Director of the Tallgrass Prairie Center,  will present "Forty-Seven Years of Prairie Recollections and Projects."
