The sugar maple, the Norway maple, and the red maple trees all showed buds. The white oak and the sugar maple trees showed some leaves that were still attached from before the winter season. Nothing seemed to be changing in the red oak tree, and no other observations were recorded in the other four. On the NPN website, the late bloom index shows a large amount of late blooming plants in southern areas, particularly Texas and Arizona. This could be due to a dry season in both of these areas, causing plants to not have the water or nutrients they need in order to bloom.
