The white oak is full of strength and beauty published August 24 2016 in The York Weekly/Portamsouth Herald, etc.
One of Aesops’ more famous fables, “The Oak and the Reed,” goes like this: "A very large
White oak leaves have rounded lobes, bark is light gray
We have a number of species of oak here in New England, the most common being the Northern red oak (one of the largest trees in the northeast) and the white oak. When most of us think of oak trees we are probably picturing a northern red oak - (Quercus rubra) the iconic oak tree. These stately trees are distinguished by the deep fissures (often red) in their bark and their bristle-tipped leaves. White oaks (Quercus alba) are just as stately but have lighter bark (hence the name “white,” even though the bark is more often a light gray rather than white) and the leaves have rounded tips.
I recently led a nature walk for the North Berwick Historical Society at a new nature preserve (the Keay Brook Preserve) in Berwick. At one point we stopped to consider a lovely old white oak. We got to talking about the respective value and uses of red versus white oak. Red oak is more valuable today for furniture and flooring due to its strength and its deep ruddy color, but back in colonial times white oak was the most valuable timber - it is strong, hard, heavy and very water resistant. I quoted Charles Fergus’ book “Trees of New England: a Natural History,” in which he writes “The nascent American navy built its famed heavy frigates, including the USS Constitution with white oak keels and planks. Yankee sailors dubbed the Constitution 'Old Ironsides' and boasted that her stout white oak hull turned aside British cannonballs during the War of 1812.” One of the history buffs in the group challenged this - she had heard that wood from the live oak, not the white oak, was used in the making of the USS Constitution. As someone with a somewhat tenuous grasp on American history I was worried that I had misquoted, luckily (since I hate being wrong) it turned out we were both right. A number of species of wood went into the construction of the Constitution. White oak went into the exterior hull and parts of the keel. Live oak, which, unlike the white oak, is short and gnarled was used in the skeleton (from “Wood that Went to War” Wood Magazine).
Back in colonial times, white oak wood was the choice wood for barrel making - wine and whiskey barrels in particular. The wood is water resistant due to woody cells called tyloses that plug the pores in the wood after it is harvested (red oak lacks these and is therefore not water tight).
One more human use-food! White oak acorns lack the high tannin content of red oak acorns and so were the choice of Native Americans and colonists who ground them up for a flour supplement (they are also on the menu for all nut-loving animals that inhabit our woods).
If I had to pick a favorite oak the white oak would probably be it because of the way they look in the late summer and fall when their trunks glow when struck with late afternoon light. I highly recommend getting out and looking for some, then standing back and admiring their uncompromising strength and their luminous beauty.
NATURE NEWS 'Dead crabs' on beach are often just old exoskeletons Rock crab exuvia Seapoint Beach Kittery Pt ME When my kids were little, one of their favorite things to do at the beach was to go crabbing - nothing official, no crab pots or bait, just their hands turning over rocks. As they got older they graduated to string with a hot dog off the dock. They’d always let the crabs go. They went crabbing because crabs are cool little animals, are fun to "race" and are a little scary to handle. My kids learned early on the right way to pick them up to avoid getting pinched. The crab-related question I get most often is about all those dead crabs that wash up on the beach, their little bodies tangled in the wrack-line. The amazing answer to that question (at least to me) is that more often than not those aren’t dead crabs but rather their shed exoskeletons. Crabs belong to a group of invertebrates (arthropods) that have rigid exoskeletons, which provide...
