Call the US Forstery Service in the area where your brother lives and explain the issue and see if they will not come and conduct a controled burn on his land. I understand that this is done for free. A burn is a very tricky thing and you have to be trained to do it correctly so that it does not get out of control, especially since this land has not been burned. I recently took a photo of a burn near Grayton Beach that got out of control and killed all the trees. (long leaf pine 30-40' tall) You might also try calling The Nature Conservancy's division in NC as well as contacting the Rob Gardner and Larry Mellichamp at NC State. There are many sources to help. Keep us posted. This is exciting!
