You're right they didn't have prescribed fires. They had a naturally occuring wildfire regime that could burn millions upon millions of acres with no anthropogenic fire breaks such as...massive land-use changes, cities, highways. A fire that started by lightning on the plains of oklahoma could burn all the way to Arkansas and work its way into some of those dissected plateaus. A lightning strike could burn up a whole river basin without burning out. After it burns it won't burn again until it's built up enough fuel again, say 3-5 years depending on aspect, slope, canopy cover, rainfall. See a pattern starting kru? Also if you worked on a fire crew you would see that prescribed fires and wildfires alike are not consistent. They create a whole matrix of areas that are burned at different levels (some areas left mostly unburned where fuel load isn't heavy). This is the beauty of biodiversity. It is no ones goal to burn everything at the same level. Hell for the most part you cant hardly get a north facing slope full of hardwoods to burn up. I love fire and love what it is doing ecologically, but that is not to say I don't see your point. I agree that there are certain situations that fire isn't as necessary or natural, and as a biologist I think that's an important point in any instance. Too much of any one thing is bad. Too much fire can be bad, too little fire can be bad. That is what adaptive management is all about, always moving forward with our thinking.kru1 wrote:How could they ever have survived the last 320 million years without prescribed burns.

forest diversity is greatest in the herbaceous layer which is the habitat most tortises & reptiles depend on
no fire = overdeveloped midstory = poor to no herbaceous layer & associated fauna
