Conservation Biology of Eastern Tallgrass Prairie: Integrating Issues of Management and Restoration for the 21st Century
Bowles, Marlin , Bell, Timothy .
Symposium Abstract: Conservation Biology of Eastern Tallgrass Prairie: integrating issues of management and restoration for the 21st Century.
This symposium is dedicated to the memory of Professor Robert F. Betz, a pioneer of prairie conservation and restoration. The symposium goal is to explore conservation biology issues for eastern tallgrass prairie. This vegetation formerly occurred as a peninsula extending from the Mississippi River eastward through southern Wisconsin and Illinois into Indiana and Ohio. The eastern location of this vegetation may confer differing ecological processes and management needs compared to western tallgrass prairie. Virtually all of the eastern prairie biome has been reduced to an archipelago of small remnants in an agricultural or urban matrix. This loss of habitat and area constrains prairie remnants through effects on plant and animal species composition and population sizes, population genetics, landscape fire processes, and direct anthropogenic impacts, as well as conflicting management and restoration needs of plants and animals. In this symposium, researchers working on eastern tallgrass prairie remnants and restorations will explore these issues with applied research and case studies as well as theoretical approaches, including synthesis of published and unpublished works. Questions that will be addressed include: How does fire frequency affect plant and animal community dynamics? Can management sustain natural community composition and structure over time? How do external biotic and abiotic factors, as well as genetics and demography, affect species level management and restoration potential? How well do restorations replicate natural populations and communities? These issues and questions have not been treated collectively in a single symposium addressing this biome. This symposium will end with a roundtable discussion among presenters and audience.
