True, and in some cases it would be best to remove many of the full-grown trees. However, often times people would rather the large trees remain and just the combustible brush and debris removed (i.e. the organic material that would be removed by a prescribed burn done in ideal conditions). In this case you have plant matter that few people would object to being gone, but it doesn't have enough economic value to be profitable to remove without artificial incentives.
