Yes that’s your overall spirit or god of nature, Cernnunos, Pan, John Barleycorn, and all that.
I haven’t looked into Osiris as a nature god but makes sense, though his story seems to have evolved into a mithras/jesus style story - it does make you winder if that’s where the whole born again/resurrection ritual comes from - ancient pagan rituals to ensure the spring happens.
The green man is similarly the consort of the lady, born in the spring and dies after the harvest where he’s sacrificed. People subsistence living were very invested in following the seasons - it bothered people a lot that winter might never end.
Damn the Bard (pronounced Dave) did a fun song about John Barleycorn which is basically about growing grain. The pagan folk music genre has a lot of inspiration for working with nature spirits and also these more pagan and hence land-oriented spirits. The druids had a lot of trinities but “Land, Sea and Sky” was one of the most important (we think, it’s not an unbroken tradition). It’s a, close to the land, survival thing.
The spirit of the land is of that local land area and is a kind of Fae. A leshiye is this kind of thing - he represent the whole forest. Although… some of the Celtic gods started out as gods/goddesses of things like shrines and heling wells, that later became deified and widely accepted. I think Brigit has that kind of history and then later wells were just dedicated to her instead of people finding the spirit of the well itself.
You also get humans who have taken to the land, particularly in America it seems where the Native Americans would work with the land and some stay with it after death. I’ve met “guardians” in cemeteries and Josephine Mccarthy talks about “sleepers” in the land ritually wedded to it to help protect it. I think I met one of these once - a native American attached to a marker stone at a field’s edge.
There’s ideas that some of the house fae - brownies and hobgoblins, also beansidhes (fairy women: banishees) - came with the early settlers on the ships. This concept is borrowed from in Neil Gaiman’s work American Gods a little.
I think some entities are universal, and are just called different things from country to country. In the UK you can get “pixie-led” - this is when you get lost in the forest from following what you thought was the trail, but realise you have been going in circles or lost the trail totally, or see a light and follow it for it to disappear and oops, you’re lost. I feel like I’ve been pixie led in my local PA woodland trails as well, but if I could talk to a local who knew, they wouldn’t call those “pixies”.
I think it’s fine to reach out and not even label the contact too, and just call it “nature intelligence” to connect with it on it’s own merits.
