Fire is good - sometimes
Livestock graze and deer browse. Therein lies the key that guides wildlife deer management. A burn will prompt new growth of browse vegetation that will attract deer resulting in more deer in a given area.
Even native Americans practiced a form of wildlife management by setting fire to grassland that supports bison. This prompted healthier prairies. Lightning serves the same purpose.
A good example is Mount St Helens in Washington. Mature forests were knocked down by incandescent pyroclastic flows and rebounded with new growth perfect for browsing. Now elk cover the slopes.
