A program entitled "Bison and Prairie Seed Dispersal: Restoring Ecosystem Functions in Reconstructed Tall Grass Prairie" will be offered April 6 at 3 p.m. at the Hamilton County Conservation office at Briggs Woods.
The presentation will explore the natural history of the bison in the eastern tall grass prairie and see how the loss of the mega-herbivores has impacted the ecology of the remaining tall grass prairies.
Pete Eyheralde, a PhD student at Iowa State University, has been involved in bison ranching in southern Iowa for the past 17 years. He is exploring the role of bison as seed dispersal agents in the tall grass prairies. He'll share findings from research being done in Iowa and how this information may lead to new techniques for grassland management, increasing biodiversity in prairie reconstructions.
