Finding lichen on the Fox Island Trail

[Cross-post from Wellfleet Conservation Trust]

Many of us grew up playing the Animal, Vegetable, Mineral? game. You had to guess an object, knowing only which of those three categories it fell into. Animal and vegetable (plant) were supposed to cover all living things.

Beard lichen (Usnea), a genus of fruiticose lichen

You can play that game on one of the WCT trails, for example, the photos shown here are from the Fox Island Marsh and Pilgrim Spring Woodlands Conservation Area, which is the site scheduled for the WCT Annual Walk on September 16, 2023.

But what if you came across some living thing that was neither animal nor vegetable? What if the thing you found looked like a plant, but wasn’t; looked like a single organism, but wasn’t; could appear as a mineral of some sort, but was full of life?

Powdered ruffle lichen (Parmotrema hypoleucinum); a foliose type

You could be looking at one of the most interesting phenomena on Cape Cod, but one that is often overlooked, even by those otherwise expert about birds, trees, wildflowers, turtles, mammals, mollusks, insects, and other fascinating flora and fauna.

That strange thing you observe might be a lichen, a composite organism made up of algae or cyanobacteria living among multiple fungi species. The fungi are in a kingdom separate from either plants or animals. That kingdom includes yeasts, molds, and mushrooms. Like animals, they cannot photosynthesize, but acquire food directly or indirectly from plants.

Greenshield lichen (Flavoparmelia caperata); foliose

Within a lichen, the fungi provide structure and attachment to a tree, rock, or split rail fence. The algae contain the green pigment, chlorophyll, which gives the green color to the lichen and captures energy from the sun to support. photosynthesis.

One common type you may find is foliose, or leaf-like lichen. Another is fruiticose, reminiscent of tiny fruit trees. There are also crustose, which attach to rocks so tightly that they can’t be removed without destroying them or the rock. They seem like the Mineral in the old guessing game. Some common crustose lichen are bright orange.

Reindeer lichen (Cladonia portentosa); fruiticose

Lichens are gray when the algae components are dead or dormant, but they may turn bright green after a rain. The fungus (which surrounds the algae) soaks up water, causing its to become more transparent, and revealing the green pigment of the algae.

See what you can find the next time you venture onto a WCT trail.

Maintaining trails

[Cross-posted on Wellfleet Conservation Trust]

A friend commented that he had done a lot of hiking and walking on nature trails, but that he’d only recently become aware of the many decisions and the work it took to build and maintain a trail. He would be interested to see what we do with Wellfleet Conservation Trust trails.

We plan these trails to entail minimal destruction to the environment. They should be obvious so that walkers can stay on them without creating social trails through the woods. But we like them to be as unobtrusive as possible. This requires a balance of engineered and natural features.

Among other things, we cut overhanging branches that pose a hazard to walkers, but leave any vegetation higher than a Celtics player, unless it’s in danger of falling. We make the trail wide enough for anyone to walk easily, but usually require a single file. We place trail blaze arrows at confusing junctions, but try not to use more than absolutely necessary.

In some places we’ve added stakes and ropes to discourage off trail walking. As enticing as that bushwhacking may be for some, it can be very destructive for the land. For example, at the Herring River Overlook trail, walking down the dune towards the river kills fragile lichen, moss, bearberry, mayapple, violets, sea oats, and other vegetation. That in turn can lead to serious dune erosion.

National Park Service plea, too often ignored

The ropes are easily bypassed, but we don’t want to mar the sites with massive barriers. We have to trust that responsible visitors will recognize the message and stay on the trail.

In many parks today we see the sign that “vegetation grows by the inch but dies by the foot.” That’s especially true on Cape Cod. Tenacious plants can survive despite salty winds off the sea, sandy, nutrient poor soil, and hungry wildlife, but only if we’re on their side.

Basal slippage

Water flow under ice on the trail

Yesterday we walked part of the way on the trail around Sutherland Pond in the Ooms Conservation Area in Old Chatham, NY, The path was treacherous because of the melting ice, so we didn’t make it the whole way. But we were mesmerized by the patterns of water flowing under the ice,

I assume this process is similar to the basal slippage seen for glaciers in temperate zones. Because of human-caused global warming, the ice melts underneath. Then the remaining ice slides on the water layer, leading to more rapid loss of the glacier.

New Drummer Cove video

A new video for the Drummer Cove conservation area has just been released. Thanks go especially to Mary Doucette, advised by Mike Fisher.

The Drummer Cove area is remarkably varied for its 11+ acres. It is also unusual for offering a 1+ mile trail with easy access.

Length & Extent of Trail: 1.1 miles; 11.3 acres plus easements

Area description: The Drummer Cove Conservation Area includes salt marsh, tidal flats, coastal bank and oak pine forest on its upland. The entire area is within the recharge area to Drummer Cove and as such falls into the Wellfleet Harbor Area of Critical Environmental Concern. The land is in State designated Priority Habitat for rare species. The four benches provide great views of the Cove.

Location: The trail head is at 170 Pond Ave in South Wellfleet. 41.91415, -70.00165

Directions: Exit Route 6 heading west for approximately 0.5 miles on Paine Hollow Road to the first stop sign. Turn left on Pleasant Point Road for approximately 0.25 miles. Turn left on to Pond Ave for 0.3 miles, the last part being a dirt road to a parking area at the trail head.

New video for conservation areas

An analysis of the use of our WCT website shows that many visitors to the site are interested in exploring the conservation areas and trails. That’s especially the case in July and August.

Responding to that need, Mary Doucette, our Americorps worker, has produced a terrific video for the Fox Island and Pilgrim Spring area.

It’s now posted in our video showcase, which will eventually contain additional WCT videos (currently just this one).
