Spring Leaf Index?

With every year comes new discoveries and understandings for me.  Which of course at my age I am grateful for as well people think you stop thinking and growing when your older, I for one am glad to see I have just started to learn.  That said I just wanted to point out the fact that I had never heard of the spring leaf index but it makes sense to me.  I mean what better way to see the change in climate then in what plants and insects do each year.

I had a post on facebook by the American Horticultural Society that sent out an article by the USA National Phenology Network they have developed a spring leaf index over the last several years that shows how spring arrival has been changing.  Spring Leaf Index?  Well let me show you apart of what they have in the article it is very interesting.
