In May 2023, the United States Supreme Court handed down a ruling that limited the Environmental Protection Agency’s ability to protect millions of acres of wetlands from pollution by saying that the EPS could not regulate discharges into wetlands unless they have a continuous surface connection to larger bodies of water. Then, just a few weeks ago, the Indiana State house passed and Governor Eric Holcomb signed House Enrolled Act 1383, which redefined some protected wetlands, limiting their protection.

Indiana’s wetlands are grouped into three tiers by the state. Class III wetlands, the highest tier, receive full protections. Class II wetlands have fewer protections, and Class I has none. Those standards were put in place in 2022, and the latest law will redefine select Class III wetlands as Class II. Wetlands are often overlooked by the general public but play a critical role in nature. Wetlands—aquatic environments that are covered by freshwater, saltwater, or a mix—are the planet’s natural waste-water treatment facilities and carbon-storing champions. They soak up excess nutrients in soil, such as nitrogen and phosphorus, which are normally found in fertilizer and can leach from farmland, and wetlands catch and hold excess stormwater, reducing flooding on that landscape. Developers are lauding the latest bill as a boon to construction, but environmental advocates are angry about the loss of the protections.

To learn more about this issue, we’re thrilled to welcome Janet Duey Professor of Rural Land Policy Chistopher Craft. Professor Craft is a professional wetland scientist, and has studied the effects of climate change, eutrophication, and other human activities on estuarine and freshwater wetlands and the restoration of those ecosystems. In 2012, he received the National Wetlands Award for Science Research. Craft has been a visiting professor with senior international scientists of the Chinese Academy of Sciences since 2010.
