Ohio is celebrating its 212th birthday with special events at the Ohio Statehouse in Columbus.
Swamps and Such
Swamps and Such is a series of video learning modules explaining the structure and functions of ecosystems and how ecosystems change over time. Geared to students in grades 7 to 10, the series details how wetlands serve as nature’s kidneys and nature’s supermarket.
It was developed in collaboration with The Ohio State University Olentangy River Wetlands and Research Park in Columbus, and was videotaped entirely at the Olentangy Wetlands.

Swamps, Marshes, Ocean inletsâ€¦All of these are wetlands, which have standing water and are not deep
Hydro periods are a fingerprint on how wetlands receive their water: from river overflows, rain, or runoff. To understand a particular wetland, scientists must understand where the water comes from, and to figure out if a wetland is OPEN or CLOSED.
Soil in wetlands lack oxygen, making the soil appear darker. Because of the lack of oxygen, plant matter doesnâ€™t break down as fast.
Different types of plants grow in wetlands according to the shape of the wetland, shoreline (slopes – steep and shallow), as well as climate and soil ph
Wetlands are home to healthy bacteria, insects, fish, amphibians, reptiles, mammals, and birds
A healthy wetland will have ample insects, and wonâ€™t be a breeding ground for mosquitoes
Wetlands produce four grams of carbon per square meter per day, or 15,000 pounds of plant material a year – twice that of a forest.
Soil particles flow into a wetland, can be stirred up, or can sink to the bottom
Plants with roots in the water can grow up through the water, or can grow as algae, which can break off and float to the surface
Phosphorus is essential in wetlands, but too much is dangerous
