Conservation Biology of Eastern Tallgrass Prairie: Integrating Issues of Management and Restoration for the 21st Century

Molano-Flores, Brenda [1].

Breeding systems issues in prairie reconstruction.

Tallgrass prairie reconstruction has become an acceptable alternative to the loss of prairies in the USA with many state/federal agencies and local groups participating in such efforts. Due to the destruction of prairies in the 19th and 20th centuries and limited research done prior to such destruction, the challenges of prairie reconstruction are immense. Although most people involved in prairie reconstruction are knowledgeable about the biology of prairie plant species, such as habitat and seed germination requirements, many are unaware of additional factors affecting the reintroduction, establishment, and persistence of these species in a reconstruction. For example, different aspects of the reproductive biology of a species, such as its breeding system, could limit its successful reintroduction, establishment, and persistence. This oversight is understandable since many guides and other books on prairie plants fail to provide this basic information, or this information is simply not available due to lack of basic research. In this talk I will provide examples of how a lack of knowledge concerning the breeding systems of prairie plants has limited the reintroduction, establishment, and persistence of these species in reconstructed prairies. I will then present the results of a prairie plant breeding system literature survey. Finally, I will outline a framework for future studies that could aid in expanding our knowledge of prairie plant breeding systems and prairie reconstructions, and discuss the limitations associated with such studies.
