What causes trees to recognize spring and break bud differs by species, but is typically a combination of a long winter chill, warming spring temperatures, and increased day length, or photoperiod. One particular tree that was leafless just a week ago, but now has small green leaves emerging is the quaking aspen (Populus tremuloides).
April 22nd is Earth Day! This year, the Earth Day Network has identified an important Earth Day theme: Trees for the Earth. This organization has committed to planting 7.8 billion trees by Earth Day 2020; that's one tree per person for every person living on the planet.
For the first time in Teton Science Schools' 49-year history, we are “all in” in supporting the organization philanthropically. By “we,” I mean parents of Teton Valley Community School and Journeys School students, as well as every full-time employee throughout the organization.
When mom or dad has just come back from a deployment, it can be hard to get back to “normal life.” Teton Science Schools is proud to partner with the National Military Family Association to serve military families.
