The trees are Walli's pine and xfrog USA West library ... western larch, if I remember correctly. Man, I suck in botanics

You also see 2 species from the NWDA Dry Bush Bundle Pack (also Walli, of course), and a couple of smaller plants: stinging nettle, greater celandine, garlic mustard and whatnot from the xfrog groundcover library.
I am also using Big Ben's pine needles to cover parts of the ground.
Cheers,
