Accepts 500 to 1000 words flash fiction at 2 cents per word.
Must be thematically about the woods/trees/forests, but can be fantasy or other genres.
Especially likes history, woodcrafting and how-to DIY topics, in nonfiction or fiction format.
UPDATE
I got a rejection letter from them. Apparently when they said they wanted fictional stories, and that fantasy was okay, I don't think they meant actual fantasy stories.
Which makes me wonder what DID they actual mean instead???
Whatever. I took the story that I wrote specifically for them and included in my anthology:
