On March 23, 2018, our group has seen a dramatic change with Boxelder-1 and Boxelder-3 in the upper canopy of 1,001 to 10,000 flower buds and less than 5% were open flowers, Figure 1 & 3. Boxelder-2 and Boxelder-4 has some flower bud growth over the past 5 days, but it also had some dying branches as well, Figure 2. There was still no breaking leaf buds or leaves in general because the temperature is still too cold. The temperature was 48 degrees Fahrenheit between 9:51 AM to 10:09 AM in the morning, and the humidity was 93% when the four Boxelders were being observed. The soil was extremely moist due to a snow storm four days ago that accumulated 5-6 inches of snow. There was about less than 5% of the ground cover with snow, and the sky was partly cloudy. Because of the snow storm, Boxelder-1 had lost some of its branches and fell on the ground next to the tree trunk. Many of the surrounding trees, not included in the experiment, suffered the same experience as Boxelder-1. (Post by D. Pitts)
