This past Sunday, six people with smartphones and one guy with a pad of paper descended on a 350 acre property in the Green Mountains near Bridgewater Hollow, Vermont. The smartphone people used iNaturalist to document about 300 observations of plants and animals (and quite a few things that might be neither, like slime molds and fungi). The paper guy was Brett Engstrom whose list of vascular plants is probably longer than the list of all the species that everyone else compiled.
