Masting Aftermath—Part 2

Another remarkable facet of the masting process is that oak trees somehow communicate with each other, so they all mast simultaneously. If instead, a tree created an abundance of acorns solely on its own schedule, the widespread acorn abundance would never occur. It is not known exactly how the trees cooperate, but it seems likely that they do so by floating chemical signals on the wind. Oak trees for thousands of acres around get in sync with each other and mast together, collectively outwitting the local critters.

The animals that are enjoying the masting feast around here are those mentioned earlier (squirrels, mice, deer, and blue jays), as well as pigeons, ducks, woodpeckers, and bears. In fact, long ago, farmers would release their domestic pigs in the forest in masting years, to fatten them up for free. The acorn nut is packed with nutrients: proteins, fats, carbohydrates; and minerals like calcium, phosphorus, and potassium.

The rub for the animal diners is that that the oak tree also imbues the acorn with tannins; they taste bitter and mess up an animal’s gut, preventing most of these nutrients from being absorbed. Clever animals have evolved a counter tactic by burying the acorns or placing them in an exposed location where rain can slowly leach some of the tannins out. American Indians—a very clever animal—used to soak cracked acorns for days in water, to make them more edible.

So, what will be the aftermath of a masting year around here? Obviously, the oak trees “hope” that come spring we will see many small oak saplings popping up—some to become mighty trees one day and keep the oak forest in perpetuity. As to the acorn-eating critters, they will eat well this winter and probably produce a prodigious amount of offspring next year. Come next fall, they will encounter harder times, however, when no masting happens, and some of them will perish. That’s the way of nature. There’s no cruelty or design to the process. Some critters must die for other to live. It’s part of the great recycling program.

There is one more interesting aftermath of a masting year that I recently discovered, while talking to a neighbor. He is an excellent hunter and keeps his family’s freezer well stocked with venison. He’s found that deer hunting this year is a little different. He says that normally he can perch in his tree stand and in time, deer will wander by, as they browse for food. This year, however, the deer aren’t moving around much, since they can stay in one location and chow down on an abundance of acorns. He has to go find them. Next year, when acorns are back to normal, he may once again be able to hunker down in his tree stand and have them come to him.
