Oaks (trees within the genus Quercus) live within a broad range of ecosystems in the United States, including semi-arid savannas in California, temperate deciduous forests in the northeast, and coastal scrublands in the southeast. Within these diverse ecosystems, different species within Quercus have adapted traits that are suited for each environment. One example of these adaptations are differences in the phenological timing of Quercus events, including leaf formation and growth, flowering, and leaf-fall.

This exercise is designed to use an app hosted on QUBES to visualize repeated phenology observations from the National Ecological Observatory Network (NEON) to examine similarities and differences among Quercus phenology at different sites. This exercise uses NEON site data from the San Joaquin Experimental Range (SJER) in California, the Ordway Swisher Biological Station (OSBS) in Florida, and the Harvard Forest (HARV) in Massachusetts.
