In defense of the trees at 14, aesthetically, it provides the golfer something of a break from the wide-open spaces of the back nine. One of the interesting things about the back nine at Lawsonia is that it sits on essentially one long, rectangular, largely tree-less piece of land, and much of it is visible from the back-and-forth fairways that comprise the nine holes. 14 is a cozy little hole, the shortest of the quintet, and certainly less demanding than the other four, although still with plenty of challenge.
Having said that, I'd agree with the consensus here that some judicious tree-cutting would be in order, particularly in back, as it would provide the golfer a sense of fear in going long. The backside drop-off is steep and deep.
12 is entirely a product of a terrific green, that I've seen some label (mistakenly, I think) as a Redan, but is really a par 3 over level land with the potential for interesting pin positions depending on the hole location relative to the fault line. It's an impressive fault line/ridge, but I'm pretty sure the one at the 3rd at West Bend is bigger/steeper.
I don't see the Eden qualities in the 12th; one might argue the 14th displays echoes of an Eden, if only because of the fairly significant back-to-front tilt of the green. Old photos at ground level of Lawsonia are hard to come by; the contrast between the Shackelford picture of the 14th and the current one is notable. Shackelford mentions an "extraordinarily deep greenside bunker" at 14, and while it is deep, I think the fronting bunker at the Redan-esque 4th is deeper.
