Exponential Beetle Population Explosion Phase
It is common for all the trees in a single neighborhood to die at the same time. In a typical small town/city situation, the 4-year period, from year 8 through year 11 after infestation, will see 60 - 70% of their trees die in that region. They are calling this the curve of death because on a graph that charts time and tree death after beetle introduction, the plotted line angles almost straight up during those 4 years, ending in all the local ash trees being dead. As insects migrate, new epicenters of Ash tree mortality pop up more and more frequently. These then begin to coalesce. This pattern will continue until eventually, all the ash are dead.

Famous quotes containing the words beetle, population, explosion and/or phase:
“Ere the bat hath flown
His cloistered flight, ere to black Hecate’s summons
The shard-born beetle with his drowsy hums
Hath rung night’s yawning peal, there shall be done
A deed of dreadful note.”
—William Shakespeare (1564–1616)
“The broad masses of a population are more amenable to the appeal of rhetoric than to any other force.”
—Adolf Hitler (1889–1945)
“Frau Stöhr ... began to talk about how fascinating it was to cough.... Sneezing was much the same thing. You kept on wanting to sneeze until you simply couldn’t stand it any longer; you looked as if you were tipsy; you drew a couple of breaths, then out it came, and you forgot everything else in the bliss of the sensation. Sometimes the explosion repeated itself two or three times. That was the sort of pleasure life gave you free of charge.”
—Thomas Mann (1875–1955)
“I had let preadolescence creep up on me without paying much attention—and I seriously underestimated this insidious phase of child development. You hear about it, but you’re not a true believer until it jumps out at you in the shape of your own, until recently quite companionable child.”
—Susan Ferraro (20th century)
