Start watching for leaf color change
 
 
Fall is just around the corner! Now is the time to start watching for color change on your trees. This is an important change that we would like you to document, so keep those observations coming! Your reports will be valuable for documenting "the beginning of the end" - of the growing season, that is. 

New to Nature's Notebook? Learn more about the 
MOP campaign. It's not too late to contribute valuable observations on these trees. Leaf color change is one of the most important events to document!

Through this effort, you are contributing directly to scientific discovery and your participation is truly appreciated.

Thank you for helping out on this important project!
