ENTS,
For me, woodland outings are chosen to serve a multiplicity of
purposes. Despite appearances, it isn't only about big trees. To be
sure, if a forest site includes an abundance of large and/or tall
trees, computing a Rucker Index is a no-brainer. My hypsometer is
going to get a workout. But, there are other forest features that I
routinely look for. For instance, there is the overall forest
composition to observe. Is the site good for particular species such
as sugar maple, red oak, white pine, etc.? Not does the site merely
exhibit those species, but are there a lot of handsome specimens,
preferably spanning a wide age range? Is the site species rich? Are
there scenic features that add to the visual impact of the site
independent of big tree forms, wildflowers, etc.? Mountain vistas,
rushing water, dramatic rock outcroppings can turn an otherwise
ordinary forest into an extraordinary one.
Well, the list of forest attributes to consider goes on and from
their totality, a loose criteria emerges that I employ to compute a
crude aesthetics index and Mount Greylock's Hopper ranks high on all
the criteria. I can find plenty of big trees to measure. The scenic
setting is unsurpassed in Massachusetts. Species variety is there
both in trees, shrubs, and herbs - and there is a reason. Greylock
has a layer of calcium-rich rocks sandwiched into its complex,
twisted geology. As a result, one can stumble (often literally) upon
a patch of spring ephemerals that carpet an area of a quarter of an
acre. This was the case for me years ago. A display of Dutchman's
breeches was off the charts. It was the closest thing I had seen to
displays that characterize some of the rich coves of the Smokies.
The streams in Greylock's Hopper have a very steep gradient and as a
consequence there are numerous small cataracts to enjoy, all in
relative seclusion. There is always a vision of sheer loveliness
waiting for the visitor. So to conclude the Saturday Greylock trip,
I've attached three more forest images. They are described below.
Image #1: Mike's observation about the impressive red spruce,
hemlocks, and hardwoods on Greylock sent me scurrying back to my
image catalog. The first image shows some handsome hemlocks
representative of what Mike spoke about.
Image #2: Early on the trail, we encountered a bigtooth aspen
that had fallen across the trail. The tree may superficially look
like an oak, but it isn't. I knew that aspen well. It served to
remind me of the past human activity in the lower Hopper by earlier
generations of white settlers. The surrounding forest is young. The
lower third to half of the Hopper saw intense human use and today's
re-growth woodlands are slowly healing past wounds. Besides a
component of bigger trees, what is conspicuously missing in the
lower Hopper is the thick, protective duff layer that one encounters
higher on the slopes, abundant woody debris that help to enrich and
stabilize the soils, and the mature patchwork colonies of herbs.
Those features are still in an early stage of development.
Image #3: I'm always on the lookout for disease-free American
beech, especially mature ones. The beech in the last image is in
good shape for now. I'm keeping my fingers crossed. The number of
mature beech in our woods with good form like this one continues to
dwindle. Fagus grandifolia never reaches the sizes in the
Massachusetts woods that I commonly see in Pennsylvania, Ohio,
Michigan, etc. I have no explanation. This one is fairly large
forest-grown specimen as beech go. There was no point in trying to
measure its height through the dense canopy, but it is close to 100
feet, if not slightly over.
