fire can be used as a method of thinning decadent plant material to
enhance other treatment types such as herbicide.
in some instances fire alone will give weeds an added advantage over
native plants.
More research is needed to determine if fire itself is a viable weed
control practice.
Fire should only be used in coordination with local officials to
address
safety issues and other consequences should a prescribed burn escape.
