Phenology Exercise

The Willows pictures seem to be a nice demonstration of flowering phenology. While one picture shows bare branches with small buds appearing, the other shows characteristic yellow flowers. The two images are a good juxtaposition of an identical plant at different flowering stages.
One image of the Coyote Brush is representative of the dormant version of the species. It is bare and completely without leaves. It is possible the picture is of a dead Coyote Brush, however, there seems to be a cycle the plant undergoes as many of the Coyote Brushes I observed had varying foliage patterns. The second image demonstrates a Coyote Brush with light leaf coverage, appearing to emerge from its dormancy.
