Another thought is to do controlled burns on your brush areas that contain high amounts of carbon. Just before these burn piles turn to ash, when they have almost burnt all the way down and have a nice coal bed, you can smolder them out with water or earth. This will cut off all of the oxygen creating an anaerobic state which produces coal (biochar). I believe this is better than just burning, as coal is a much more stable carbon that regulates nutrients and water absorption. If you replenish these areas to replicate a biodiverse meadow by using multispecies "cover-cropping" you will not only lessen the possibilities for fire to spread but it will also help build healthy soil. Dr. Christine Jones recommends using a minimal of 8 different species of covercrop seed but more is better. We're talking grasses, legumes, herbs, wildflowers, etc. But the sky is the limit. Just depends on what you want to do with the area. I'm just suggesting something that will help build soil in the long run. I also highly suggest to whomever has not listened to her lectures to give it a peep. She has a ridiculous amount of information for building soil fertility, in which goes against the much regurgitated information out there. Hope that was at least somewhat helpful.
