Prescribed Burn In Longleaf Pine Forests

This is a 10 to 12-year-old, long leaf plantation. That was recently burned. The landowner wanted to get fire back in here to try to open up the stand to get rid of some encroaching hardwoods and loblolly and short leaf pines and to written to stimulate the ground cover it's, pretty dense. So he was very cautious about the kind of fire. He got in here. You didn't want it to get too hot, but he wanted to be hot enough to do some good and controlling some of these other species from the outside is. Hard to tell really what the fire did.

We see some Brown needles, Brown leaves, but a lot of green on the trees we have to go inside the stand to really see what the fire effects were. And one of the concerns of the landowner was the amount of fuel that was in the stand. He was concerned that the fire would be too hot and would kill his residual stand of long leaf, but he still wanted the fire to be hot enough to kill the young loblolly and shortly Pines that were coming in as well as the to pond. The idea was to open the stand-up allow light in and to stimulate the ground cover. Now you see a lot of dead or browned out needles and leaves on the trees.

This is from the scorch from the heat of the fire that Brown these out they'll eventually fall and add to more fuel on the ground. If we look on the ground, we can see this nice layer of new Dvila needles that have fallen since the fire underneath. You can see the ones that burned or the charred needles that remained.

And you can. See it didn't burn all of them also there's some left. So basically is fire skimmed across the surface without doing creating too much heat and leaves enough litter for the next fire. Now we can also see the young loblolly x' that are coming in a lot of these are pretty well been scorched from the ground up a lot of these will die as well as the Y open over here is a thicket of to pond.

You can see the needles still own the branches. It was basically scorched, but it was probably top kill at the. Base the fire didn't, necessarily catch the bush on bushes on fire, but it girdled them at the base, and these will be top killed. And those stems are pretty much dead. However, they will re-sprout, so he'll have to come back in the next one or two years to get another fire in here to keep knocking that.

To pond back this prescribed burn was conducted under the ideal conditions for what was required here. The burn was conducted under relatively cool weather, light winds and relatively high humidifies. So the fire intensity didn't get too high, and the flame links were fairly low. So although the heat scorched the needles, the flames were probably 1 to 2 feet as we can see from the char on the bark of these young trees here. Now, the bigger trees got more scarred Shnen, our char on the bark because there were a lot more needles, right under them. So that the flames may have got a little higher on the bigger long leaves.

But for the most part, it was relatively mild. You.
