Here's another line on trees dying which could hold some answers, or at least clues:
[WARNING: some people who believe in AGW mythology may find this material confronting and offensive]
“A good example of adaptive cycles in comes from the spruce/fir forests that grow across large areas of North America…Among the forests’ many inhabitants is the spruce budworm…EVERY 40 TO 120 YEARS ,POPULATIONS OF SPRUCE BUDWORMS EXPLODE , KILLING UP TO 80 PERCENT OF THE SPRUCE FIRS …In a young forest, leaf/needle density is low, and though budworms are eating leaves and growing in numbers, their predicators (birds and other insects) are easily able to find them and keep them in check. As the forest matures and leaf density increase the budworms are harder to find and the predators’ search efficiency drops until it eventually passes as threshold where the budworm breaks free of predator control and an outbreak occurs…The managers in this system … become locked into using ever-increasing amounts of pesticides because the industry wouldn’t be able to cope with the shock of a massive pest outbreak. The industry had little resilience ,and yet the continued use of chemicals was only making the problems worse…”
