Forests Responding to Multiplex of Changes

Trees travelling west: How climate is changing our forests,
Ecological Society of America, August 1, 2018.

“...studies on the impacts of global temperature rise have suggested that the range of trees will migrate poleward and upward.”

“...different combinations of changes in temperature and precipitation can result in different impacts, and different species can have different responses.”

"...found that 73 percent of tree species have experienced a westward shift while 62 percent have experienced a poleward shift. It appears that the shifts are largely associated with changes in moisture availability."

“The results suggest that changes in moisture availability have stronger near-term impacts on forest dynamics than do changes in temperature.”



I’ve been watching the predominant direction from which our seasonal precipitation comes shifting from the Northwest to the Southwest over the past forty years.

This shift in the direction of our seasonal winds & storms is accompanied by changes in their timing, temperature, frequency, and the density of rains across the whole seasonal progression. This has profound implications.
Trees in many parts of California are migrating from the Northwestern-facing aspect of their terrain, which used to predominantly face incoming storms, to the Southwestern-facing aspects, which are now predominantly facing incoming storms.

All forests are responding to all these changes in the character and timing of our seasons, as all these changes are accelerating and deepening.
