User's notes
In degraded woodland patch of mixed thistles under native Cherry tree; the majority of those depicted by the image (with deep serration) are Scotch thistles, I think; some Spear thistles shown closer to the bottom of the photo. Sprayed with herbicide but not mapped because I couldn't get the accuracy required to map with Field Maps.
