  • Choose a location where you can see the forest landscape. Use the Land Cover tool in the GLOBE Observer app to take photos in each cardinal direction, up, down, and also take a "Feature Photo" of the landscape.

NOTE: Leaf color changes rapidly and regular, repeated observations are appreciated!
