GP has a big track of land nearby, and a few years ago we kept seeing cropdusting planes dropping below the treetops and decided to check it out. While watching them dusting pines we also saw them planting pines. They had a dozer that pulled a trailer. The trailer was enclosed except for the back. It was a mexican sitting in the trailer laying plants in the planter ( worked like a tobacco planter ). The dozer was going back and fourth over the land that had just been cut, over stumps and through ditches like they wont there. gave me a headache just watching , dont know how somebody could take that pounding all day. Looking out the back of the trailer he could only see where they had been so he didnt know if the next second was going to bring a stump or a hole.
As for replanting I am guessing each state has its own rules ??? I see some land around here get replanted and some is just left to grow back on its own.
Yup, you can plant that way where it is flat. I worked timber cruising with guys who had been the planter on the trailer and they blamed their back problems on doing that work. It sounded like they took quite a beating. They also tend to plant in rows that way. Out here, planting by hand just doesn't make for those straight rows, you are always having to go around a rock or log, and that's a good thing, it makes the plantations look more like nature planted it.
While in exile and working in the Up Nort Mid West, I heard constant complaints about the spacing of the rows and trees. I think they were 9 feet apart. The thing is, when those trees were planted, I bet nobody ever dreamed there'd be a processor and forwarder working in them.
