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:
“After the planet becomes theirs, many millions of years will have to pass before a beetle particularly loved by God, at the end of its calculations will find written on a sheet of paper in letters of fire that energy is equal to the mass multiplied by the square of the velocity of light. The new kings of the world will live tranquilly for a long time, confining themselves to devouring each other and being parasites among each other on a cottage industry scale.”
—Primo Levi (1919–1987)
“This was the Eastham famous of late years for its camp- meetings, held in a grove near by, to which thousands flock from all parts of the Bay. We conjectured that the reason for the perhaps unusual, if not unhealthful development of the religious sentiment here, was the fact that a large portion of the population are women whose husbands and sons are either abroad on the sea, or else drowned, and there is nobody but they and the ministers left behind.”
—Henry David Thoreau (1817–1862)
“Moderation has never yet engineered an explosion ....”
—Ellen Glasgow (1873–1945)
“The Indians feel that each stage is crucial and that the child should be allowed to dwell in each for the appropriate period of time so that every aspect of his being can evolve, just as a plant evolves in the proper time and sequence of the seasons. Otherwise, the child never has a chance to master himself in any one phase of his life.”
—Alan Quetone (20th century)
