 It's not going to be a thing that we would burn this area off and then never have to do it again. It's something that you have to do. While we were setting up for this I just glanced at the ground behind me. There's two little cedar trees about half inch tall. They won't quit. We have to stop them. The natural system you know they talk about we're kind of in the mixed grass prairie region here and probably looking at five to ten years for a fire return interval and and that's kind of what we probably want to do with the burn association is probably looking at doing that and actually Rich is doing that here looking at doing another burn here. Since this is all kind of brand new to South Dakota we've been South Dakota State University. We've started conducting some studies. What we were finding in that study is that after eight years the growth of those cedar trees just really starts exploding. I mean it just it's an exponential growth and it can really and then it just really starts smothering out you know your forage underneath that cedar tree and then you just have a thick cedar forest again. Really what we're finding the sweet spot is about eight to ten years. You don't want to go past that for a return interval for another prescribed burn to keep everything at bay.
