Participatory Science Project

Stainless steel bands called dendrometers measure tree growth.

About the project

Our aim is to measure tree growth throughout the world by using a simple but sensitive technique that anyone, anywhere can use.  To date, the tree banding network covers several thousand trees in more than 42 countries and 48 states in the US! Measuring tree growth has allowed us to gather information about how trees respond to local weather and global climate change.
