About the project

Thank you to everyone who made this project possible! This project is now over.

The Global Tree Banding Project's aim was to measure tree growth throughout the world by using a simple but sensitive technique that anyone, anywhere can use. The tree banding network covered several thousand trees in more than 42 countries and 48 states in the US! Measuring tree growth allowed us to gather information about how trees respond to local weather and global climate change.
