nope,,, just fewer trees per acre so that there are sufficient resources to support them, and a slight shift in species... the more moisture-needy species may have to move up 500 feet or so in elevation, which is equivalent to a few degrees of latitude farther north.
saving most habitats in a forest environment is NOT futile in the face of climate turbulence. Preventing widespread stand-replacement events is not only feasible, but using prescribed fire is way more economical than putting out intense fire. Wildfire suppression costs about $2500 per acre on the average, but treating the fuels before a fire event is about $250 per acre, often much less if underburning is done on a large scale. I suspect that the Waldo Canyon fire will cost an astronomical amount, but i haven't seen the data yet.
