Today's Report Includes:
How to Participate in Journey North's Leaf-Out Study
We hope you'll help us measure spring's northward journey by reporting when
leaves emerge on your trees. Here's how: Adopt a local tree of one of the following species. Visit your adopted tree on a regular basis. Sketch the buds on the same small branch each time you visit. Watch the bud open, the tree bloom and the leaves emerge. When its leaves are the size of a U.S. (or Canadian) quarter, report to Journey North. That's our definition of "leaf-out".
Spring Fever: Measuring "Growing Degree Days"
Introducing Journey North's Regional Leaf-Out Coordinators
We live in a huge hemisphere, and our success in tracking spring will depend on contributions from many people. This year, a volunteer network has stepped forward to help in this process. You may receive a personal reminder from these classroom Coordinators when the leaves are about to emerge in your region. Special thanks to Gustavus College student intern Christian Gilbert for spending the cold month of January in Minnesota to coordinate this project! And thanks in advance to these teachers and students for contributing their time:
* If your class would like to take responsibility for one of these regions, please let us know!
