If you had missed it on NPR, here's a link to a segment on green spaces and tree-lined areas and how it can alter human behavior (though I have a hunch you listened and enjoyed this bit as much as I did).

No doubt salt problems.

Red Oak is the state tree of NJ!

the kids i work with (first graders) are studying plant life cycles. most of the books for young children on this subject refer to the oak tree as an example of a familiar plant and its familiar seed. the only problem is that oak trees just aren't that common around here, understanding the basic concept, they've been picking up various seeds and nuts and showing off their "acorns." the teacher keeps telling them they're not going to find acorns in the desert (possibly in a riparian area?) but i guess the books give an element of romance to the mighty oak and the kids really want to be a part of that. (the also get a little cranky when they learn about "winter" in the temperate regions and demand to know why they can't have some snow.)

Red-Scarlet-Black Oak??

I grew up in NH, where, as I recall, we had primarily Northern Red Oak. I am trying to learn black and scarlet oaks and distinguish them from red. Down here in Stoughton we have a lot of black, scarlet, and who knows what else, mixed in with the red. I have learned that the black (not sure about the scarlet) has much more of a horizontal component in the bark of the mature trees than the red, which is dominated by its vertical fissures and is somewhat smoother. The black takes on more of the effect of rectangular or square clumps.

Can anyone add to this or correct it, and or/give some ways to distinguish scarlet oak?

But back to red oak, it has such large xylem or phloem vertical passageways in its wood, that you can blow bubbles, as if from a somewhat clogged straw through a 3-4 inch chip of the wood, such as what a couple sharp axe blows might whack off. Big ones up country could fetch a special price, if the local basket company took a liking to one on your land.

A forester told me that black oaks have flatter, shallower acorn cups than scarlet oak. I don't think I could tell the difference.

Scarlet oaks also have more distinct bark with a interlocking trail pattern, black oaks have tight blockier bark with rusty inner bark that tastes bitter!
