I received an email today with the below info. No clue why they waited so long to pass this on but here is a paste from their website...

• > "Field Station Concordia and the New England Leaf Out Project have teamed up on a citizen science project to collect leaf out times.

We are investigating the effects of climate change on the tree species of New England. Using both remote sensing and direct observations, we will monitor leaf out times across the region, and whether trees leaf out earlier now than they did in the past due to warming temperatures.

We hope you will help us gather observations of leaf out times this spring to add to the available database of current and historical observations.

If you live in Maine, New Hampshire, Vermont, Massachusetts, Rhode Island or Connecticut, all you need to do is:

Find one or more trees from the list below in a place that you visit regularly
This spring, starting in mid April in Connecticut and late April elsewhere, check your tree every couple of days, and look for the first signs of leaf out
Submit your observations here
Please include any information about the tree's environment (high on a mountain, urban street, etc.)"

I have no association with their website but feel free to post this in other forums you frequent.

Their website has more info plus examples with pictures and is linked below...
