Aquatic Research

 

Highlights from our work:

  • Approximately 60 percent of translocated mussels survived their first year, indicating this is likely an effective mitigation effort.

  • Head-starting and releasing turtles is costly and will not mitigate population declines on their own in the I-355 corridor, as adult mortality is too high. Less costly alternatives include protecting nests, controlling predators, and releasing hatchlings.

  • The streams along the I-90 corridor were quite species-rich and diverse for fishes.

  • Twenty-one threatened or endangered species and two sensitive habitat types have been found in the Rt 53 North Extension corridor historically, but thus far only 6 of the species have been found, 4 plants and 2 fishes.

  • Desirable wetland species have become established in bioswales; however, invasive species remain among the dominants in approximately half of the bioswales.

  • At the North Chicago Mitigation Site 450 vascular plant species were identified, including populations of four threatened and endangered species, and numerous locations of high-quality prairie and wetland habitats.
