Plainfield has numerous red maples (Acer rubrum) as street trees. They're most easily spotted in the spring when their early-blooming bright red flowers catch your eye as you pass.
Red maples are also noticeable in the fall, as their foliage turns red or orange before dropping. The trees can be distinguished easily from the other maples likely to be seen in the area. Unlike sugar or Norway maples, red maple leaves usually have only three lobes, not five. Another clue is their red color: red maple leafstalks, buds, samaras (winged seed cases), and flowers all have some red color. Colorful spring flowers and autumn leaves make for an attractive tree. Red maples' biggest problem is a tendency to split in strong winds, a drawback that it shares with several other maple species.
They are also susceptible to heart rot, leading to wind-snapped trunks.(2)
How are people helping red maples usurp the dominant role in eastern forests? In a multitude of ways. European settlers started the process by cutting down all but about two percent of the eastern forests' trees to make farms. Farming moved westward, and eastern farms were largely left to revert to forest by the early twentieth century. Red maples, although usually inhabitants of wet soils, were very adaptable opportunists.(3) They quickly inserted themselves into the newly open spaces.
Oaks and hickories have thick bark that protects them against forest fires. Thin-skinned red maples are much more likely to be killed to the ground by fires. Modern humans almost completely suppressed forest fires, stripping oaks and hickories of their natural advantage over red maples. Fire suppression had a second effect on the tree balance. Fires created open spaces ideal for light-loving oak seedlings. Maple seedlings are much more shade-tolerant than oaks and thrive in the darker environment created by fire suppression.
We did another favor for red maples by making the landscape very friendly to deer. Vastly expanded deer populations suppress oak numbers by eating huge quantities of acorns.
Yet another boon to red maples was our importation of gypsy moths, prodigious eaters of oak leaves. We also introduced Dutch elm disease and chestnut blight, dealing a knockout blow to other red maple competitors. Finally, there is evidence that red maples are more tolerant of acid rain than most tree species. Man's best friend? Dog. Red maple's best friend? Man.
More on chestnuts: Plainfield has a native American!
Robin Gates wrote that we have an American chestnut in Plainfield. You don't have to trek to Monmouth County to see one. Bill Santoriello planted one at 946 Madison Avenue when he owned that property in 1992. The tree was obtained from The American Chestnut Foundation and is now eight or nine inches in diameter at breast height.
Although the tree will eventually succumb to chestnut blight, it might live a long time. A stand of 200 native chestnut trees about 80 years of age was recently discovered in Georgia (4)
The Plainfield tree recently produced a large crop of chestnuts.
