One Trail Twelves Times - December: A Study in Reds and Greens

December's One Trail Twelve Times walk was scheduled for December 16, but several days in advance the forecasters said that there was a good likelihood that we'd have rain that Sunday afternoon.  So, to ensure that I'd have a visual record of the Beech Springs Trail in December, I walked the trail to take photographs on Thursday afternoon, December 13.  Sunday afternoon wasn't rainy, but it was misty and foggy, and the small group of walkers decided to tackle the trail anyway despite the dampness - a good decision, because we all enjoyed this final episode of the series spanning twelve months.  When I returned from the trail,though, I downloaded the images I had taken with the group and realized that the setting on the camera had slipped and many of the images I had taken, especially early into the walk, were too dark.  So, the following Tuesday morning, December 18, I returned to the trail and recaptured some of the ruined images.  All this is to say that the images below are a compilation of the best images captured during three walks on the Beech Springs Trail this month.

The beginning of the trail in mature woods

The first year rosettes of invasive, non-native garlic mustard (Alliaria petiolata); in the spring they'll bolt and produce thousands of seeds in sickle-shaped pods.

Soon after we entered the mature woodland at the beginning of the trail, I noticed Spotted Wintergreen (Chimaphila maculata) growing alongside the trail.  This handsome native ground cover is probably present year round, but simply lost amidst the Japanese honeysuckle (Lonicera japonica) growing more vigorously on the forest floor.  We've undoubtedly walked by this plant 11 time before and never noticed it.

Non-native and highly invasive porcelain-berry (Ampelopsis brevipedunculata) is my biggest invasive plant headache.  This Asian member of the grape family (Vitaceae) becomes established in a field when birds eat its fruit and defecate the seeds.  Then, the perennial vines clamber up anything that will support them (usually a tree), and the roots run underground and send up periodic sprouts, spreading the infection ever wider.  The roots become very, very thick and full of stored nutrients, so repeated cutting barely fazes the plant.  One it gains a foothold in a field like this, it is very difficult to control because broad-leaf herbicides that kill porcelain-berry kill all the desirable broad-leaf plants, too.

This is a porcelain-berry "knot" in the middle of the grassy trail.  I don't know what the technical botanical term of this feature is, but my staff and I call it a knot.  As I mentioned above, well-established porcelain-berry roots send up sprouts periodically, allowing this pernicious plant to colonize new areas.  The knots can have a half-dozen vine sprouts, each one trying to ascend into the forest canopy.  When we established the trail, we cut several of these root-sprout knots; repeated trail mowing has caused the sprouts to die back, but I'd bet that the roots below are still alive.

With nearly all the vegetation died back, I devoted quite a bit of time during the walk to searching for mantis egg cases attached to the stems of plants, but the only cases I found were attached to sweetgum saplings (Liquidambar styraciflua).  Though it was probably intuitive, such placement was good planning on the part of the the mantids because the herbaceous old-field vegetation will get mowed in early spring, while the saplings - and their attached egg cases - will be spared.

The trail's eponymous springs only run a few hundred feet through the forest before they discharge into a small, perennial tributary  of our main creek.  Though I've posted images of the springs before, I had yet to venture off trail to get images of the stream itself.

Most of the stream's watershed is developed, either with houses on large lots, or as part of a huge (40-acre) grassy field used annually for a fundraising carnival and horse show by our local hospital.  So, the stream is very "flashy" - bearing modest flows most of the time, but turning into a raging torrent during storms.  Water quality is not particularly bad, but the floods scour the stream bed, carry lots of suspended sediment, and erode the banks, so the stream is not really much of an aesthetic amenity.

Goldenrod galls, produced as a defensive mechanism by goldenrod plants when a goldenrod rod gall fly (or peacock fly) (Eurosta solidaginis) injects an egg into the plant's stem, are common throughout the meadow.  Once the egg hatches, the gall provides a cozy retreat in which the fly larva can overwinter.  However, not all the larvae make it through the winter; some fall victim to Downy Woodpeckers (Picoides pubscens), which cling to the dried stem and peck a hole into the gall to extract a juicy winter snack.  Most of the galls we inspected had been raided by a woodpecker, like this one had.
