In this lecture, the writer is trying to tell us that there had been a lot of forest fires, and the way that decrease the destruction of fires.
One is simiply the longer lives and improved health of trees. In some areas of hickory and oak forest on Eastern Seaboard, tfire suppression has alloowed the maturation of so many trees that the treetops form a continuous canopy.
There is evidence of useful effects of fire suppression closer to the ground as well. Low bushes that would be burned out in a forest fire can clourish. Chemical test on areas that have recently experienced forest fires demonstrate that burning decreases the overall amount of nutrients in the soil. Suppressing fires prevent a decrease.
Also wildlife can benefit. In the eastern hickory and oak forests, the suppression of fires has meant that forest animals, the population of insects, and animals, especially deers, have increased.
