Hello! I am brand new to the forums here, and new-ish to being an active iNat user, though I first downloaded the app about 2 years ago. At the time I only understood it as something you could use to help ID plants …I had no idea about logging observations and the vast community here!
In any case, I have a question about the “arrived in the region via anthropogenic means” designation for an observation. This designation popped up for me on an observation I logged yesterday, found here: https://www.inaturalist.org/observations/75717837.
I noticed another observation of Trillium grandiflorum in this location received the same designation. I’m wondering if anyone can tell me why? Is it explicitly known that someone planted this trillium here? I ask because Trillium grandiflorum is most certainly native to this region. The observation occurred in a wooded park area where many other native woodland plants can be observed, including star chickweed, Jack-in-the-pulpit, bloodroot, downy yellow violets, etc. All of these are plants that are very frequently found in the same locations as Trillium grandiflorum.
So I’m not sure why it should be assumed that the trillium was planted there by humans, unless it is explicitly known that someone planted this specific trillium? I’m just not understanding why this observation should receive this designation.
Thanks in advance for your thoughts and help!
