Before tree farming there were natural pine forests here consisting mostly of longleaf pine. Almost all of the natural pine, oak, cedar, and cypress in the area was logged.
In recent years, the forestry division has planted over one million longleaf pine seedlings in Point Washington to help return the area to its natural state.
Most of the burns go on in areas where longleafs are growing or where they will be planted. In other areas burns reduce the amount of underbrush so that in the event of an unplanned fire, the fire doesn't spread out of control.

The seedlings you see that grow like weeds are likely sand pines. They are the ones with extremely shallow roots which grow very close together.
