Is there any way to act on this knowledge? Maybe fund small fenced off "islands" where cattle and fire are excluded every 1,000 acres or so?All fires are not created equal. The fires in the flint hills have long ago turned from good to bad. Since they started using early intensive grazing where they burn every year and double stock for the first half of the season, quail populations have tailed off. Quail need cover to both nest in and escape predators in. With no cover left over hundreds of thousands of acres, depredations is greatly increased and nesting success is greatly decreased. Further, many of their burns are late in the season, multiplying the problem. SE Kansas went from tall-grass native prairie in the first half of the 1900's to fescue predominantly in the last half. Forestation increased some 30% or more in that part of the state since the '80's. Add in changing ag practices, less dependence on wood for cooking and heat, and any number of variables ( urbanization, neonicotinoids, roundup everything) and it gets us to where we are today.
Of course, one might argue that intense pasturing and burning are driven by the need to feed the multitudes. But that is not actionable (or at least, would most likely lead, correctly so, to future war crime trials). As should any forced moves to veganism - but that's just my opinion, of course.
