Some good news about land conservation from the Southern Cumberlands

From the Open Space Institute:

“In a series of six targeted land conservation projects completed within a short six-month period, nearly 13,000 acres have been acquired and added to Tennessee state parks and wildlife management areas.”

These lands add to the 17,000 acres already protected by OSI in the last few years in this region. The grants that made possible these projects aim to protect biodiversity in a changing climate. The conservation lands will also provide public access to open space and encourage sustainable forest management.

Partners in these projects included The Nature Conservancy, The Conservation Fund, The Land Trust for Tennessee, and the State of Tennessee (TN Wildlife Resources Agency and TN Dept Environment and Conservation).

Post-truth chestnuts?

After editorial discussions that were “a bit more serious and somber …[than] in some other years,” Oxford Dictionaries has named “post-truth” as its international word of 2016. But of course we’re not “post” any truths, especially not the truths of biology and physics that don’t bend in the foul winds of demagogues.

Nor in the errors of bloggers like me. Some taxonomic truths have come to light about the not-so-somber matter of tree identification. So, with many thanks, I share my colleague Dr. Hill Craddock’s take on the “chestnuts” from my last post.

He writes that the plants in the “photo could be in the genus Castanea, with the true chestnuts…but I think they may really be fruits of trees in the genus CastanopsisCastanopsis is a large genus (more than 100 species) of Asian trees closely related to, and very much resembling Castanea.  Some species share characteristics of Quercus [oaks] and Lithocarpus [“stone oaks”].”

So, the chestnuts from China (see additional photo below) are in fact close relatives of chestnuts, sometimes called “chinkapin”. These trees are evergreen and generally not frost-hardy.

Dr. Craddock continues with “a curiosity:  ‘Shii’ is the Japanese name for Castanopsis.  Shiitake (Lentinula edodes) are grown traditionally on Castanopsis cuspidata in Japan, although in the US, they are mostly grown on oaks, or other hardwoods. Shiitake literally means ‘Castanopsis mushroom.'” So, next time you are eating some US-grown shiitake mushrooms, consider their genus-crossing journey. I’d be interested to know whether the different tree substrates result in different experiences on the palate. Does oak-grown shiitake taste the same as Castanopsis shiitake? I know that local shiitake growers here in Tennessee claim a much richer flavor for shiitake grown on solid logs rather than sawdust bricks. Perhaps the species of wood also makes a difference?

I send many thanks to Hill Craddock for taking the time to share his knowledge and to Todd Crabtree for making the inquiry that led to our exchange.

Glimpses of botanical and avian diversity at Nan Kun Shan Forest Park and Crosswaters Ecolodge

Our Chinese hosts kindly arranged a short visit to the forests Nan Kun Shan Forest Park. Driving inland from Shenzhen we first passed around the mega-city of Guangzhou — one of China’s tech hubs (the e-device that you are now reading with likely came from there) — which sits amid the anastomosing branches of many large rivers. From these urban flooplains we  passed into low hills, mostly managed for timber and fruit production, then to the steep-flanked mountains. In the mountains, protected forest parks are interspersed with vacation resorts and small villages. One of China’s first ecotourism projects is located here, the Crosswaters Ecolodge. The American Society of Landscape Architects gave Crosswaters an “Honor Award,” writing that it is, “tremendously inspiring to see a project in China that is designed as a celebration of its natural and cultural place. Impressive and extraordinary resourcefulness in salvaged and native materials make a more elegant and beautiful environment. For projects in this region it stands out for using found and salvaged local materials.” Guests stay in rooms and cabins made from locally-harvested bamboo, built in riverside forest clearings:

The plant life in this region is an interesting mix of subtropical and temperate species. Here, bamboo grows alongside banana and oaks. Callicarpa bodinieri (or perhaps japonica), Asian relative of American beautyberry, is common in the understory.

This oak or oak relative grows on the slopes that had not been converted to bamboo groves. I’m working on finding species/generic names…suggestions are very welcome!

Two different species of Castanea (relative of the American chestnut) grew on the slopes above the river:

Two sizes of chestnut. Neither looked or tasted like Castanea mollissima, the Chinese chestnut grown in cultivation in the US. Four other species of Castanea grow in south Asia.

Birds in this region are also spectacular:

“More than 100 college presidents issue joint letter to President-elect Donald Trump”

This news from the University of the South’s website:

“Vice-Chancellor John McCardell is one of 110 college and university presidents urging Donald Trump to take a more forceful stand against “harassment, hate and acts of violence.” The campus leaders have issued a joint letter to President-elect Trump.” Read the full article here.

Thank you, Vice-Chancellor and President McCardell, for taking this stand and asking president-elect Trump to make good on his promise to be a president for “all Americans.”

All Saints’ Day, Ediacaran Edition

In honor of Life Triumphant, all the ancestors, known and unknown.

ediacaran-fossils-3

These are Dickinsonia fossils from the Flinders Range in Australia. They’re about 570 million years old, from the “Ediacaran.” They are among the earliest known fossils of any multicellular creature on Earth. Make that: of any multicelluar creature in the Universe.

I came across these specimens during my visit to the Yale Peabody Museum a few years ago. I was there to look at a different group of fossils (youngsters, just 33 million years old) and walked past a cabinet with “Ediacaran” on the label. Gob-smacked, I begged a look and my hosts casually opened a drawer to reveal The Tomb of the really, really ancients. Could I feel the reworked remnants of their DNA squirming and leaping in my every cell? Did my cranium feel hairline fractures rush every which way as my skull’s apex lifted in astonishment? Did my pentadactyl limbtips and opposable thumbs quiver as I held the camera?

Ah, beatific visions.

 

Now we see through a glass, (darkly, nope…) Tiffany, Chihuly

At the Museum of Fine Arts in Boston, light streams through vitrified pigmented sand:

From Louis Comfort Tiffany, Parakeets and Gold Fish Bowl, a piece made in about 1893. Tiffany’s use of glass to evoke the birds’ colorful and varied head patterns is stunning.

Sadly, the work now stands as an unwitting eulogy. By 1910 the Carolina Parakeet was extinct in the wild and the eastern US had lost its only native parrot. A few lingered for half a dozen years in zoos, but these individuals died without leaving offspring. Occasionally, the birds’ reflections surprise us with a gleam in museum galleries, but their light is almost entirely gone.

A few steps away, Dale Chihuly’s Lime Green Icicle Tower (2011) uses some of the same palate, but without direct representation and, I hope, presaging of extinction.

The piece is 40 feet high, about 10,000 lbs of glass in conversation with the sun, the museum’s atrium windows, and the vegetation outside. From some angles, inner and outer reflective surfaces combine and tangle. Intended or not, this creates a coda to Tiffany’s work: what we conceptualized as Nature is now, whether we like it or not, wrapped into Humanity. Understanding this, might we, perhaps, perhaps, snuff and shadow less light?
