Yesterday I wandered around Duke Farms, the home of the tobacco heiress, Doris Duke, in Somerville, New Jersey. It is now maintained by the Doris Duke Foundation, which has as part of its mission "to be a model of environmental stewardship in the 21st century"
But before I get to pictures there, I passed this tree. In an earlier post I mentioned I had seen pear and cherry trees blooming in August, but I didn't have my camera with me. Well, I came upon another, a flowering crabapple, one of several, all of which had only a handful of leaves left among them.
But on to Duke Farms, where I stopped on the driveway, aghast at the endless array of dead and dying trees.
The magnificent greenhouses are now closed to the public permanently.
Looking in every direction from the parking lot, trees are in dire straits.
Even ground cover like pachysandra shows the classic discoloration that is becoming so familiar.
Perennials like hosta are damaged.
Ditto for lamb's ear.
All these dead and dying trees, and many more I didn't photograph, before I even got to the visitor's center!
There are many pines and cedars in varying states of decline - none are intact.
The azaleas in front of the greenhouse have very few leaves, and those that remain are tiny and reddened.
It's easy to overlook the damage in a forest, and therefore important to took closely at the leaves of even very young trees.
I guess the good news is nasty plants like sumac aren't being spared.
Neither is poison ivy.
Or deadly nightshade.
This is Virginia Creeper, a pretty vine that turns scarlet in the fall.
Random weeds I don't even know the name of are showing signs of toxicity.
Here is the second letter I have sent to the Board of Trustees of the Doris Duke Charitable Foundation.
August 31, 2009
Dear Dr. Henry, Dr. Shaffer, Dr. Bowman, and Dr. Donnelly,
You may recall that I wrote the Board of the Doris Duke Charitable Foundation last February regarding the impact of climate change on trees at the property of Doris Duke's home in Somerville, New Jersey. This was forwarded to and then answered by Gene Huntington, Director, Natural Resources. Our exchange is pasted below.
Mr. Huntington was kind enough to respond with a lengthy discussion of various threats to trees, but more or less ignored my concerns about climate change, preferring to focus instead on disease, age, deer and invasive species. This no longer surprises me because virtually all of the professional foresters and conservationists to whom I have broached this subject react with similar dismissiveness. It was Upton Sinclair of course who observed, "It is difficult to get a man to understand something when his salary depends on his not understanding it."
It is not my intent to disparage Mr. Huntington. I believe he is quite likely a sincere, knowledgeable and dedicated friend of nature. Instead, I am writing because I am convinced it is necessary to take a very hard look at the evidence. We can no longer afford to be romantic about restoring the environment, it is urgently in peril of permanent loss.
Since I last wrote you, the condition of vegetation all along the Eastern Seaboard has deteriorated dramatically, and universally. Thus not only trees, both deciduous and coniferous, but shrubs, annuals, and even weeds are damaged. My understanding of the source has progressed as I have been researching the cause and I now believe it is quite likely that the addition
of ethanol to gasoline, which produces acetaldahyde, a precursor of peroxyacetyl, is the primary toxic component in the atmosphere which is poisoning plants.
Ozone from gas, coal and oil burning is well known to be unhealthful to both plants and humans, and should certainly be curtailed - but the unprecedented rapidity of tree death, and characteristic changes in leaves now prevalent leads me to the conclusion that it is the relatively recently mandated use of ethanol likely to be the major factor...since ozone has been around for decades.
It was not merely a storm that damaged 300 trees in Central Park. They are weakened by the toxic composition of the atmosphere, which causes the stomata in their leaves to close, and in a sense, smothers them.
It is my belief that because the Doris Duke Foundation has a mandate to be a steward for the environment, the Board would be remiss if they did not vigorously pursue what is clearly an existential, imminent threat to the environment which, if unchecked, will lead swiftly to ecosystem collapse and mass extinction. Mr. Huntington closed his message to me, after describing the planting of trees and removal of invasive species at Duke Farms, with this: "Again, thanks for your interest, and we hope this helps at least explain a way in which we are trying to help remedy the insightful situation that you describe."
Although planting native trees and removing invasive species are admirable activities, they are utterly inadequate to address the situation I describe. The remedy is supporting research about the impacts of volatile organic compounds on vegetation, demanding the EPA require the immediate cessation of ethanol additives, and encouraging the rapid deployment of green energy to power plug in vehicles, with the ultimate objective the eradication of all greenhouse gas emissions.
Today I went to Duke Farms in Somerville where I could have easily spent many hours photographing scores of dead and dying trees. I have uploaded some here: witsendnj.blogspot.com where I have also been posting links to peer-reviewed published scientific research on this topic.
I would appreciate it if you would take a look at the blog to see what the trees at Duke Farms actually look like before disregarding my description.
Please feel free to contact me for any reason.

And here is my response, to which I never received another reply:
Dear Mr. Huntington,
Thank you for your reply and I am glad to know that you are working so assiduously on the landscape at Duke Farms.
I am familiar with the problems you describe and have spent almost 30 years battling invasive species, mainly poisen ivy, bittersweet vines, and the cursed multiflora rose on my 13 acres in Oldwick. Three years ago I put up a deer fence and realized I could have skipped planting so many trees because without the deer, they were coming up all over all by themselves.
However I do beg you to carefully consider what I wrote. It is not only old trees that are in decline. Young trees are also losing their bark and limbs.
Further, the conifers of all ages looked perfectly normal 4 months ago and now it is difficult to find one of any age that is not losing needles at a highly abnormal rate. You can see their trunks, and through to the other side. Evergreen shrubs are also damaged, such as yew, boxwood and rhododendron.
My pet theory for this lately is that it doesn't get cold enough for the trees and shrubs to hibernate, so when we get a cold snap, such as in January and again this last snow storm, the cold damages the leaves/needles of evergreens. I have been watching very closely and the shrubs made steep downturns after each of these weather events.
Another thing I've seen which I never have before, is black streaks down trunks, that look as though the tree is wet even if it's not. I wonder if the sap freezes and expands, cracks the bark, and then starts weeping out as the temperature rises.
Please do me a favor the next couple of days as you go about your routine, and pay attention to the plants and woods around you. I would be very interested to see what you think as I am sure you are a trained observer.
