The observations below can become clues to exchange with your partner through the
Phenology Data Exchange. Print a copy of this list and gather as much of the information as you can. Don't worry about those items you miss, and feel free to add ideas of your own.

What to Report to Journey North
Many of the events below should also be reported to Journey North. Others should be exchanged with your partner only. Please report all those events marked with the owl to Journey North. Remember: We need help collecting spring data from as many people as possible. We can't track Spring without you!
