Pine Barrens Soil Horizons

Yesterday, I transplanted a small piece of Carex pensylvanica, Pennsylvania sedge, from my sister’s property in Ocean County, New Jersey. This species is common on her property.

She lives in the pinelands of New Jersey. The canopy is pine and oak. The duff layer – the natural “mulch” of dead plant material deposited on top of the soil – is composed of mostly pine needles, with some oak leaves.

Here’s a view of the clump I extracted.


And here’s the “back” view, where the blade of the spade I was using sliced through.

I only just realized I had a nice slice of the upper soil horizons.

The slats of the tabletop are 2″ wide. The entire depth of the soil slice is only about 3″, 4″ including the duff layer.

The white is fungal mycelium that has colonized the duff layer, starting the process of decomposition.

After I moved this clump from the table, I noticed tiny beetles, at least two different species, had clambered off. They fell through the slats before I could photograph them or otherwise observe them more closely for identification.

This small slice represents at least five different macro-species – pine, oak, sedge, and beetles – and one micro: the fungus. If we could somehow inventory all the micro-invertebrates and micro-organisms, there might be hundreds, or thousands, of species in this photo.

It’s tempting to think of species as singular “things,” to be contained in our cabinets of curiosities, our checklists, our collections. Any species is not any one thing, but a population, containing genetic diversity that slowly shifts and drifts across space and time. Each species is part of a larger whole, an unbounded fractal of complex relationships.

Yes, I grow many native plant species in my garden. For one reason, I can learn to recognize them. I never want to forget how artificial my construction is. However I may hone my garden, whatever beauty I can construct here, and pleasure I may offer from it, it doesn’t compare to the transcendence I experience of wild things in their natural habitats. All this diversity at home reminds me of how much more there is, still, in the world, and how important it is to protect it.

Gateway National Park Public Design Competition

There is a Public Competition open for envisioning and designing the future of Gateway National Park, also known as the Gateway National Recreation Area. The deadline for registration is next week, February 28, 2007.

Gateway is huge. It covers 10,374 acres of land and 16,233 acres of water, a total of 26,607 acres. For comparison, the entire island of Manhattan is about 12,800 acres. Gateway consists of three “units”: One in New Jersey, and two in New York City. The Jamaica Bay Unit straddles Brooklyn and Queens. It comprises the majority of Gateway: it covers 19,752 acres, 12,367 of which are water, the remainder of which are 15 different parks, beaches, wildlife refuges, and other sites of interest. Over 330 species of birds have been recorded in Jamaica Bay Wildlife Refuge, the largest designated area within the Jamaica Bay Unit.

Even if you don’t intend to compete, there are hundreds of pages of documentation, scores of maps, and innumerable photographs of Gateway available in the Site Brief section of the competition Web site. Although some details are available only to registrants, much of the information is available, intentionally, to the public at large, to help inform public discussion:

Gateway was designated the first urban National Recreation Area on October 27, 1972, exactly one century after Yellowstone became the first national park in the United States and the world. Thirty-five years later, Gateway continues to struggle to meet the aspirations of its founders, to negotiate its relationship with the communities that surround it, and to balance the goals of historic preservation, environmental conservation, and active recreation.

Gateway presents a significant regional resource with incredible infrastructural, ecological and cultural value in the New York metropolitan region, hosting endangered birds, fish and shellfish breeding grounds, marinas, playfields, and cultural relics. It is also the site of combined sewer outfalls, treated wastewater effluent, abandoned buildings, degraded habitat, drowned marshes, former landfills and vast asphalt runways.

Both the complexity of Gateway and the scope of this design competition call for an immense amount of background information about the park. The materials provided throughout the Site Brief area of the website are taken from a Research Report prepared by a team of investigators from Columbia University’s Graduate School of Architecture, Planning and Preservation. The report is comprised of written chapters, extensive mappings, external primary sources and site photographs. It is intended to provide a comprehensive overview of the conflicting issues facing Gateway historically and today.

We are pleased to make the majority of this information available to both competitors and the public-at-large. The Research Report can be downloaded in its entirety for the duration of the competition, and selected images and mappings are available for public browsing throughout this section of the website.
