Invasive species are a leading driver of biodiversity loss in aquatic systems. Removing established invasive species may restore native communities and ecosystem function, and also reveal unexpected indirect connections between invasive species and other community members. In an attempt to restore the native littoral food web, we removed ~95,000 invasive rusty crayfish (Orconectes rusticus) from Sparkling Lake from 2001-2008 via trapping, and changed fishing regulations to increase predation of crayfish by littoral fishes.

Lakes and wetlands are overlooked components of regional and global carbon cycling, but in water-rich regions such as Wisconsin’s Northern Highland Lake District, these ecosystems can store over 80% of the organic carbon despite covering less than 35% of the landscape.
