Mesic Hardwood Forests may not tolerate extended droughts.

Submitted by sdhandler on

The potential for climate change to increase the frequency of extended droughts poses a threat to these forests for multiple reasons, including increased moisture stress, wildfire occurrence, and susceptibility to other stress agents. Hardwood forests occurring on moist, rich soils may be buffered from short-term droughts or seasonal moisture stress. CO2 fertilization might also increase the water-use efficiency of some species, reducing the risk of moisture stress.
