sophia s hypothesis
Sophia’s Hypothesis

When the QHEI (habitat quality) escalates, the IBI (fish diversity) will escalate with it.

This darter is from Big Darby Creek, where we went this week.

Liz’s Hypothesis
  • As ammonia levels increase in the Rocky River Watershed, the IBI, which is fish diversity, will decrease.

how can you help
How can YOU help?
  • Be cautious of what you use when you deice! Some salts will run into the river as ammonia. Ethylene Glycol and Propylene Glycol are eco-friendly choices.
  • When you paint around your house or wash your car, be careful not to dump it into the storm drains.
  • Restore the riparian zones so they can keep the pollutants under control.

These practices will keep the environment balanced with the economy.
