Hi @raphael1c,
Good news - – it’s not too late.
On your original Forum question at https://forum.inaturalist.org/t/how-do-you-add-observations-to-a-project/35216/5, I gave directions for specifying your woods as a place and setting that up in the Project. I don’t think you got back to that question to read the replies.
Anyway if that’s not clear you are welcome to message me directly. Once the project is set up, all those observations people made should be in it.
