Saint Louis University

Welcome to the St. Louis Ozone Gardens

The desire to educate about rising background ozone levels led SLU's Center for Environmental Sciences to create a network of "Ozone Gardens" around the St. Louis metro area.

Many plants show signs of damage at ozone concentrations as low as 40 parts per billion (ppb).  This ozone concentration is now usually reached every day in the Midwestern United States during the spring and summer, the primary growing season for crops and wild plants.

Through the Environmental Protection Agency's (EPA) Environmental Education Grant Program, we have funds to support installing outdoor Ozone Garden in EPA's Region 7 (IA, KS, NE, MO).  You can read the full request for proposals (RFP) here.  We invite your institution to apply; proposals are due March 1, 2017. You can contact Jack Fishman or Kelley Belina at the email addresses below with any questions.

What is an Ozone Garden?

The plants growing in our Ozone Garden exhibits are all sensitive to ozone air pollution.  They show damage if ozone levels are high in the air around us.  Because these plants monitor the health of their environment, they are called "bio-indicator" plants.

Saint Louis University staff, and student helpers and volunteers, collect data on the amounts of ozone leaf injury on the plants throughout the growing season.  There is also an ozone (O3) monitor and a weather station at each of our sites recording conditions every 15 minutes.
To see the ozone and weather data from our gardens go here, and click on "Graph GO3 Data".

We hope you can visit one of our gardens in the St. Louis, MO metro area this summer.
