RE:burn

I would recommend that you refrain from "tidying" up after a burn (unless you can really justify on solid biologically grounds, for example a dsire for seed production instead of a maintenance of a natural community).  Natural burns were most certainly very patchy, and that patchiness is an important component of the heterogeneity in a community.  Unburned patches can serve as refugia for sensitive insect or plant species.

Less than favorable burn conditions resulting in patchy burns were likely a very important mechanism for formation of savannas, at least here in Iowa.
