Greetings!
Depending on where you live, it may not feel much like spring. But maples, oaks, and poplars across the country are starting to break bud, starting the flush of green that accompanies leaf out.
Thank you for your interest in helping us track the "Green Wave" over the course of the spring season, and the spread of seasonal color across the country in the autumn.
Observations of individual plants, taken on the ground, are critically important for resource management and scientific research. Plus, it's fun to see how the timing in leaf-out varies across the country...how will your trees stack up against those in other states?
We'll provide you with periodic updates on this project over the course of the spring, summer, and fall of 2018. This year, instead of regional messages we are sending out a single national message. You'll get to see what is happening with maples, oaks, and poplars all across the country!
If you tracked Green Wave plants in previous years, we are so glad to have you join us again in 2018! Observations submitted over multiple years from the same locations are the most valuable to scientists using your data.

If you haven't already registered one of the target maple, oak, or poplar species that are a part of this campaign, learn about getting started. The plants we are focusing on are:

What you've been reporting across the country
|
Observers across the country have submitted data on Green Wave species at 223 sites so far this year. The map below shows the sites where observers have reported a "yes" for breaking leaf buds.
Observers have already started to report breaking leaf buds for maples, oaks, and poplars. Colored bars on the phenology calendar at right indicate when observers have already reported "yes" for breaking leaf buds.
Don't forget to report those "no" observations that precede your first "yes". These negative data are critical for pinpointing when a phenophase such as breaking leaf buds first begins.
Earn your Tree Tracker badge by reporting observations on maples, oaks, and poplars in 6 separate weeks in the same year. See it on your
Thank you
for helping out on this important project!
