Stan,

I burn approximately a third of The Proving Grounds annually.  The percentage varies based on weather and other factors.  The correct prescribed fire program for a pine plantation would depend on the type of pines, the age of the stands, other management activities such as herbicide and fertilizer, and the management objective.  I would mislead you by offering a simple answer.  Prescribed fire is a great tool when used appropriately, but can be extremely damaging and/or dangerous if misapplied.  If you work with a consulting forester, they may be able to offer you site-specific advice.

Growing Deer together,

Grant
