One of the centerpieces of this Celebration is the City Nature Challenge, a collaborative effort undertaken by residents, students, teachers, and scientists to document the diversity of life across the Greater Burlington Area during a four-day bio-blitz (April 29 - May 2). We are one of over 400 cities around the world participating in the year’s event, and it promises to be an exciting opportunity for global collaboration and connection as we engage in a friendly competition to see who can make the most observations of nature, who can find the most species, and who can engage the most people. Participants from Winooski, Colchester, South Burlington and Burlington will utilize the iNaturalist app to document their observations, and our collective observations will be displayed on the City Nature Challenge iNaturalist Website.

City Nature Clocks

We will also be using iNaturalist this spring is to create a set of City Nature Clocks featuring local focal species observable in Burlington, South Burlington, Colchester and Winooski.  Unlike conventional clocks that portray the 12 hours of the day in a circular fashion, nature clocks instead feature the 12 months of the year to visualize the timing of recurring seasonal events in nature. Timing of budbreak, leafing, flowering, fruiting, and leaf coloring are the commonly observed events in the plant world, while the timing of bird migration, the dates of salamander courtship, and mammalian hibernation cycles are examples from the animal world.  Over the course of the three months between the vernal equinox and the summer solstice (March 20 – June 20), volunteers will record their observations of the 60 focal species using the iNaturalist app, and the results will be rendered in the form of City Nature Clocks on the Burlington Wildways website.
