Help the Girl Scouts protect our planet

SciStarter citizen science projects about trees

It’s officially Fall — let’s talk trees, please! Trees cool and moisten our air, fill it with oxygen, store carbon and provide food, fuel, and building materials for humans. And, more than that, they’re just plain nice to look at!

That’s why the Girl Scouts have made trees, and the environments that support them, a big part of their citizen science efforts. But you don’t have to be a Girl Scout to take part! Find out about the Girl Scout Tree Promise and other tree- and nature-focused initiatives below.

NASA GLOBE Observer: Trees guides you on how to use your smartphone to report local tree height measurements that complement NASA satellite observations.


Scientists use the data to study carbon ecosystems (trees take up carbon from the atmosphere) and the global environment.
