“The water from a 2-inch downpour, for example – more than 54,000 gallons per acre – is captured almost entirely by an oak forest’s leaf litter and the organic humus it creates. Litter and humus don’t hold this water indefinitely, but they do corral it on-site just long enough for it to seep into the ground, replenishing the water table on which so many of us depend. In areas with no leaf litter, the same 2-inch rainstorm causes a flood.”
