In a Science paper published in 2009, van Mantgem et al. discussed widespread tree mortality in the US, and linked it to both drought stress and increased air temperatures. In the past decade we’ve seen catastrophic death of piñon pine, sudden aspen decline, decimation of large swaths of various pine species, and death of yellow cedar. How are these changes a function of climate, and what are the effects on hydrology?
How do these phenomemna feed back into global climate change?
I'm seeing huge stands of Aspen, Poplar, Cotton Woods and now Willow dying out. Explanation? The latter are still near water sources.
