Trees do spread naturally. We're revegetating 10 acres of land with native plants and its amazing to see the spread every year. But that's not relevant in a situation where you're planting them for an end result like sequestering carbon (e.g. a renewable pine plantation). Then you obtain the land, plant the heck out of it with seedlings, then thin them out http://www.gfc.state.ga.us/resources/publications/PineThinning.pdf http://www.gfc.state.ga.us/resources/publications/PineThinni... at regular intervals. Way more bang for the buck than planting a few and hoping for natural propagation.
