Trees contain valuable information about Earth’s past, so much so that studying their rings may help fill in hidden gaps in Ohio’s environmental history.
Trees are the planet’s living lungs; they remove carbon from the atmosphere to clean the air, and filter our water. Yet depending on their species, not all record long-term environmental changes, such as fires, floods and droughts, in the same way.
By analyzing how various types of tree rings grow in response to these distinct weather-related events, researchers discovered that some can act as useful tools in managing local watersheds, that drain water into nearby streams and rivers.
