THIS WEEK at HILTON POND |
TREE BARK BAFFLER #1: With the arrival of winter, many trees at Hilton Pond Center have lost their leaves, making identification a bit more difficult. Last week, with the debut of Tree Bark Baffler #1, we challenged you to take a look at photos of trunks from six native Piedmont trees to see if you could figure out what species they were without using hints such as leaf shape, twig configuration, or overall silhouette. This week, we're letting you see how you did by checking your answers against the descriptions below. All text & photos © Hilton Pond Center
Entries sent in response to Tree Bark Baffler #1 bore out our comment in the first paragraph above: trees are indeed hard to identify from bark alone, especially without any frame of reference such as texture, terminal bud, tree shape, habitat, etc. We regret that no one identified all six trees correctly; in fact, four out of six was the best anyone did, but thanks go out to all who entered. Nearly everyone got #3 Black Cherry right; fortunately, we didn't include a photo of a really old specimen at Hilton Pond Center that lacks the tell-tale lenticels. The most commonly missed tree was #6 Pecan, which was the one we thought would be hardest; no one identified it correctly, although fellow Newberry College graduate Dan Koon of Columbia SC (left) did place it correctly in the Hickory Family so we're awarding him half a point; he also got four other IDs correct to earn a score of 4.5 out of 6. Several entries confused #1 Eastern Red Cedar with Bald Cypress (Taxodium distichum); the latter has bark that can be similar in color to red cedar's, but it isn't stringy. Also confusing was the blocky bark of #2 Flowering Dogwood, which some folks thought was Common Persimmon (Diospyros virginiana); persimmon bark typically has much deeper furrows with blocks that are more pointed rather than flat. #4 Southern Red Oak, whose bark is somewhat nondescript, was a puzzler for the majority of entrants; the overlapping ridges of #5 White Oak proved much easier to identify. Unfortunately for Dan Koon, 4.5 isn't high enough to earn the coveted Operation RubyThroat T-shirt prize, but his score will give him bragging rights until a future Tree Bark Baffler #2. Until then, we'll continue studying trees at Hilton Pond Center--just in case we bump into Dan someday and he asks us to perform the baffling task of identifying photos of bark specimens from his own backyard.
