  • silvery salamander Vermilion County Illinois

    Silvery salamander

    In a video produced by Outdoor Illinois, INHS aquatic ecologist/herpetologist Andrew Kuhns describes his work in conservation and transportation compliance. He provides an overview of a project, funded by a State Wildlife Grant, to study the population demographics of the Illinois-endangered silvery salamander. Watch the team set up a drift fence to intercept salamanders migrating to their breeding pond. After collecting information, which will aid researchers in assessing population sizes, growth of individuals, and reproduction, the salamanders are released to the breeding pond.

So – for the summer, at least – I also am nocturnal.
