Highlights from our work:

  • 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.
