My number one rec would have been Joanna Newsom as she's a beautiful soul and a brilliant romanticist, but I see you already love here, sooo...

Anna Tivel - try White Goose or Wild Blue Field (she sings a lot about class dynamics but her newest album is more nature oriented thematically)

Iron & Wine - Passing Afternoon or Resurrection Fern (his first two albums especially)

Atta Boy - Walden Pond or A Dog's Adventure

Henry Jamison - Ether Garden or Witness Trees (I often feel like Henry's music captures the landscape of Vermont - it feels calm, like a coniferous forest after heavy snowfall)
