Join Our Spring Wildflower Phenology Annotation Blitz!


Vermont Bloodroot flowering phenology for iNaturalist annotated data. There are several hundred observations that are not annotated! Help us add important data. (click on image to visit page).

Long-term flowering records initiated by Henry David Thoreau in 1852 have been used in Massachusetts to monitor phenological changes. Phenology—the study of the timing of natural events such as migration, flowering, leaf-out, or breeding—is key to examine and unravel the effects of climate change on ecosystems. Record-breaking spring temperatures in 2010 and 2012 resulted in the earliest flowering times in recorded history for dozens of spring-flowering plants of the eastern United States.

You can be like Thoreau right from home! There are thousands of images of plants that observers like you have added to the Vermont Atlas of Life on iNaturalist. But, they have not been annotated so that we can easily track phenology.

Help us add this valuable information. It's easy and fun! All you have to do is look at beautiful images of plants and note whether they have flower buds, flowers, or fruits.
