The trees are Norway Spruce, River Birch, and a couple of Scotch Pines and one surviving White Pine which is not suited for our region. All are 4-5" caliper, really too big to have bought and hoped to survive our hot weather but I got too good a deal to pass up. I also bought 3 other White Pines, but they didn't make it through the early part of spring. Going forward, I'll probably stick with Cottowoods and Eastern Red Cedar which are native species. Not the prettiest trees, but are very tolerant.
My experience is that smaller trees will be just as large as bigger trees in 10 years. The example someone used was that if you take a 1" tree, a 2" tree, and a 4" tree and plant them at the same time, all will be about the same size after 10 years because takes the larger trees more time to get over the transplant shock. Might not happen if you move with a tree spade, but we used our skid loader with a rented 24" posthole digger.
Thanks for everyone's input-I'm leaning towards an electric trash pump at the small pond because I can just run a cord to the barn. This morning I used my neighbor's pump, and was surprised at how quickly it filled barrels. For the other location, I'll probably look into the gas powered pumps. I didn't realize that they were so reasonably priced.
