About this episode

This episode discusses invasive species management at Emiquon Preserve, focusing on the common carp population and its impact on water quality and habitats.

After decades of draining the land for agriculture, restoring water to The Nature Conservancy’s Emiquon Preserve helped recreate high quality wetland, lake, and marsh habitats that were once common along the Illinois River. Maintaining these high-quality habitats requires monitoring and effectively managing invasive species. This episode's discussion will focus primarily on our efforts to better understand and manage the common carp population at Emiquon to reduce negative impacts on water quality and vegetative habitats.
