As a dead tree decomposes the heterotrophic organisms eating it release a large amount of the stored carbon back into the atmosphere as CO2 as we heterotrophs are want to do. That's where a lot of people stop and give up.
What I think a lot of people forget is that plants naturally spread. If you plant a tree and it survives for 50 years, it's producing seedlings for up to 90% of it's lifetime. If even two seedlings can become trees you have removed the CO2 from the air rather permanently.
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/PineThinni... at regular intervals. Way more bang for the buck than planting a few and hoping for natural propagation.
