In 2015, post construction, we conducted fish, mussel, aquatic macroinvertebrate, and bird surveys in the corridor and found:
- 335 live individuals of 12 mussel species
- Captured live individuals of the state-threatened Slippershell Mussel – Alasmidonta viridis
- 3 most common species were:
- White Heelsplitter – Lasmigona complanata
- Plain Pocketbook – Lampsilis cardium
- Cylindrical Papershell – Anodontoides ferussacianus
Birds
We conducted searches and circular plot counts and found
- 61 species of birds
- 1 state – endangered species, Osprey, at 3 locations
- Sparrows were the densest species group overall
Fish
Using minnow seines and backpack electroshockers in 2015 we found:
- 46 of the 192 fish species native to Illinois
- 3 state-listed species
- Iowa Darter
- Gravel Chub (7)
- American Brook Lamprey (1)
There was no significant difference in species richness, community evenness, nor species diversity compared to our 2012 samples
In 2017 we found:
- 45 species
- Gravel Chub (2)
- American Brook Lamprey (3)
In the Kishwaukee River:
- 32 species of fish
- 4 species intolerant of poor water quality
Aquatic Macroinvertebrates
We used the ILEPA 20-Jab Allocation Method for wadeable streams
- Sites ranged from “Poor” to just under “Good” based on habitat assessment
- Based on macroinvertebrates, the Kishwaukee River rated “Excellent,” Coon and Mosquito creeks “Good,” and Spring Creek “Fair”
Bats
In 206 we deployed acoustic monitors at 4 stream crossings
- we recorded in May, July, and Septembr
- over 14,000 bat passes were recorded
- 10,566 were identified by software
- 9 species of bats were detected
- Big Brown, Eastern Red, Silver-haired, Little Brown, Tri-colored, Evening, and 2 federally listed species – Northern Long-eared Bat and Indiana Bat
