One Trail Twelve Times - November


Asian bittersweet's (Celastrus orbiculatus) irresistible yellow carpels and red fruits tempt wreath makers, who then discard their handiwork after the holidays, thus helping to spread this menace.
Five walkers joined me for the penultimate installment of One Trail Twelve Times on Sunday afternoon, November 18, under partly sunny skies with temperatures in the upper 50s.  At first, I thought that we might complete the circuit of the Beech Springs Trail in record time because the somber, dun-colored fields seemed to offer little to observe.  But, in the end, we actually returned a bit later than usual; there's always plenty to enjoy.

When we entered the woods and immediately came upon a red oak (Quercus rubra) brought down across the trail by Hurricane Sandy.  Though the staff had cleared the canopy of the oak out of the path, the limbs, branches and trunk remained.

At the woods-meadow edge, the white pine saplings were damaged by bucks rubbing their stems and eating their tender tops.  Must give them piney fresh breath!

When we left the wet meadows, crossing the Eagle Scout footbridge across the gully, I looked downstream.  Normally, the sight line is limited by a tangle of nearly impenetrable vegetation, but with the onset of autumn many of the plants had lost their leaves, revealing a pool and high, rocky banks adorned with Christmas ferns (Polystichum acrostichoides).

With the leaves gone from the native spicebush (Lindera benzoin) shrub layer, it has become obvious that the shrub layer is not all spicebush but also includes a healthy population of invasive, non-native jetbead (Rhodotypos scandense )that, like many non-native plants, holds its leaves longer than the natives.  Such a strategy gives the invasives a competitive advantage over the natives because they can photosynthesize longer than the natives. 


As the group rounded a corner in the trail, we came across a large white oak (Quercus alba) uprooted by Hurricane Sandy.  If you look closely at the left side of the image, you'll see that that the oak toppled into a neighboring tree, uprooting that tree as well like two tumbling dominoes.

Around the next bend in the trail, we came upon another sad casualty of Hurricane Sandy--the Pileated Woodpecker Tree. This bird cherry (Prunus avium) snag bore an unmistakable rectangular  hole excavated by a Pileated Woodpecker and was a landmark along the walk.  Bird cherry wood is not strong in the first place, and the insect damage at its base had clearly weakened the tree enough to topple it during the hurricane.  The fallen trunk had blocked the trail, so my staff had cut it into manageable sections to clear the path.

On close inspection, we discovered that fungi had colonized the tree, and had begun to emerge through cracks in the bark - like fiery lava oozing out of the earth!

The final leg of the trail passes along the center of a long double allee of white pines (Pinus strobus) planted in the 1920s.  Two of these pines lost major limbs during Hurricane Sandy, both of which came down across telephone and cable lines.  The telecommunication lines never snapped, but the limbs bowed them down to the ground.  These were among the last tree (parts) cleared off utility lines in our area because, unlike electricity, they were not essential and because the serve had not been interrupted.

Because the end of this series of rambles is imminent, the "regulars" began to hector me about choosing another trail for the next year and repeating this program.  I'm reluctant to commit to one weekend afternoon a month again (though, in all honesty, it hasn't been onerous or interfered much with my life, and I've really enjoyed the walks and camaraderie).  I've discussed this with Kali, but haven't made a decision yet.  I'm thinking of doing one walk a month on a different trail each month until we complete a walk on every trail in the preserve.

As always, Scott, a highly informative and enjoyable blog. How many trails in the preserve? I really like the photos here, and the writing, as per usual, is strong. You even got to use the word "penultimate." Doesn't get any better than that.

Happy Thanksgiving to you and Kali.

Hi and "thank you" again for a beautiful and informative walk along your trails. The fungi are amazing. I so enjoyed walking with you and your group - I could see and feel and hear and smell and absorb every glorious moment.
Love Gail
peace.....

Packrat: Thanks for your compliments; I really appreciate them. The preserve has a dozen trails, and they ranging in length from about 1/4-mile to well over a mile. The shorter ones wouldn't do for a guided walk, but the longer ones certainly would lend themselves to a nice ramble.

Gail, I certainly wish that you could join us! I'll do my best--at least one more time--to impart the "feel" of the trail--next time in December. Welcome aboard.

It is quite lovely to virtually take these hikes with you and your fellow hikers. I like the idea of a monthly hike to record the changes. The photos are so beautiful. I've been reviewing my photos of the past few years, and started noticing repeating patterns even of the timing of the iridescent clouds.

Thank you, Robin Andrea. Kali asked me what insights I've gained after walking the same path over a year's time. I don't have any grand revelations to share, only small surprises that I try to include in my accounts of each walk.
