I work for the State of Vermont, where I map natural communities and plants. In some of my spare time I use iNaturalist to map neat things I find during explores. I am originally from southern California. During my time mapping California's vegetation, I got very good at identifying plants from far away, which comes in handy helping identify observations here.
Sometimes I take samples as part of my job and add photos of them to iNaturalist. Please don't take samples unless you are sure it is legal and is not harming the population of the species.
