Beauty Is as Beauty Does

 

Driving along a newly opened or renovated highway, a motorist is apt to see young trees newly planted beyond the road shoulders or in the median, if the road has one. That’s a fine thing, except it occurs to the motorist that it’s the height of summer, daily high temperatures are in the 90s, and besides the meager contribution of hit or miss thunderstorms, there hasn’t been any measurable rainfall in weeks. Why did the landscape contractor plant those trees at such a time and subject them to such misery?

Economics are the determining factor rather than the health and survival of any individual tree. A homeowner with a quarter acre lot may have six or eight trees on it, and understandably with numbers like that the health and survival of each tree is important to the homeowner. A landscape contractor charged with planting trees along miles of highway may be dealing with six hundred or eight hundred, or even thousands of trees. The industry standard is to expect losses in the 30 to 40 percent range within the first three years, which is the typical length of the maintenance contract after planting. That’s two hundred trees dying within three years out of six hundred originally planted.

The landscape contractor is constrained to replace dead trees within the three year maintenance window, and of course the anticipated costs are included in the contract. It all seems like such a waste. Nature itself is wasteful, of course, because not every young tree survives to maturity, particularly not ones that sprout along a baking roadside in the middle of summer. Still, wouldn’t it be better for the trees if the contractor waited until autumn to plant them?

 

For the trees, yes it would, but again economics are the deciding factor. For most landscapers, at least the ones who care less about hiring knowledgeable staff and more about just having able bodies on hand, labor is relatively inexpensive. The cost of replacement trees has already been included in the contract. What is expensive is hauling water out to the trees and looking after them. If regular rains come along after planting, even if the weather remains hot, then so much the better. That goes into the profit column. The contractor may have other, more profitable work already lined up for the prime fall planting season. The summer highway job was a good filler to keep the crew and business going in what is normally a slow season for planting.

 

It would be better if economics weren’t focused entirely on the short term and instead looked down the road more. When Lady Bird Johnson pushed for the Highway Beautification Act in 1965, she no doubt saw it as a way to improve the nation’s roadsides over the blight of too many billboards and unscreened junk yards, and it was. Her efforts on behalf of the environment both during her tenure as First Lady and afterward were probably the greatest contribution to the nation of any First lady in the twentieth century. She influenced state and local highway departments in establishing standards for roadside plantings. Those standards, however, could use some revision.

Many regulations concerning highway and parking lot plantings require a landscape architect’s blueprints and signature. A landscape architect does not necessarily know any more about plants than a landscape designer or the man in the moon. In many cases, as any knowledgeable landscaper can tell you under their breath after having worked with a landscape architect’s plant selection and layout, they are amazingly ignorant. A landscape architect has a college degree and is state certified, that’s all. The result is that because of reliance on landscape architects’ plans the first rule of proper landscaping is often violated on account of their ignorance or carelessness – the right plant in the right place.

The second revision to regulations bears on the competence of landscaping companies. By the appearance of the results along too many highways,  communities and highway departments seem to be awarding landscaping contracts on the basis of just about anything but competence. Would they award a building contract to a construction company whose buildings habitually failed within five to ten years? Unfortunately, that is what they do when they award a contract to a landscaper whose slipshod planting and mulching practices result in tree failure beyond the usual three year maintenance replacement window. Some problems with trees take several years to manifest themselves, and often the problems are due to the incompetence of the landscaping contractor. Knowledgeable input from local tree stewards and arborist societies about the competence of various landscape contractors during the process of awarding contracts would most likely improve the efficiency of the subsequent plantings over the current 30 to 40 percent rate of failure and make Lady Bird Johnson proud (and as they say in the South, “Bless her heart“).

Planting for Tomorrow

 

“Someone is sitting in the shade today because someone planted a tree a long time ago.”
― investor Warren Buffett, known as the “Oracle of Omaha”.

If you have to be outside in the heat of a summer day, there is no sweeter relief than the shade of a large, spreading tree. Even staying indoors you can benefit from a shade tree if it helps cool the building you’re in, reducing the need for air conditioning. The first six months of this year have been the second warmest on record in the lower 48 states, after 2012. The National Weather Service accounts for climate data from 1895 onward, and according to their records 2016 was the warmest year of all.

Drought has not developed as widely this year as in the recent past. The northern Plains states and southern Arizona have been hit hardest with drought this year, but elsewhere rainfall has been adequate. When it’s very hot, sufficient rainfall to keep plants, and especially trees, alive is crucial to mitigating high temperatures in the short and long terms, and maintaining trees as counterweights to further warming. A mature shade tree such as an oak can transpire over a hundred gallons of water in a day, drawing it up from it’s roots and losing it to the atmosphere from it’s leaves. Drought stresses trees and makes them vulnerable to pest problems, and if dry weather continues for several years in a row, the decline and death of trees can be due as much to pest damage as to lack of water for metabolic processes.
Summer is not the best time to plant trees because heat stress makes keeping up with watering difficult, but it is a good time to plan for planting in the best season, autumn. Balled and burlapped trees have been grown in a field, dug up with a root ball at least two or three feet wide and tall, and then the root ball wrapped in burlap to retain moisture until replanting. Such trees are tempting to buy because they promise shade sooner since they are bigger than container-grown trees. There are a number of reasons to resist the temptation.

 

Balled and burlapped trees are more often than not never root-pruned in the field, with the result that when the nursery digs up the tree, they cut off almost all the fine, fibrous roots at the outside of the tree’s root zone, and those are the roots which do the bulk of water and nutrient uptake for the tree. Because they are bigger than container-grown trees, balled and burlapped trees are more expensive to purchase. They are also more expensive to maintain for the first several years after replanting because they need intensive care on account of having to regrow fibrous roots. Until then, balled and burlapped trees will often not grow at all, and will even be surpassed in size and vigor in many cases by initially smaller container-grown trees.

The reason is trees grown in containers have all or most of their fibrous roots. You can check this with a gentle tug on the trunk to see if there is some resistance to coming out of the container. Some unscrupulous nurseries will dig undersized field-grown trees and pot them up, knowing they could not sell them as balled and burlapped trees. Such trees will give little resistance to coming out of the container unless one or more of the large anchor roots is stuck in the side. There will be minimal fibrous root development. Another, perhaps simpler way to check for fibrous roots is to brush away some of the potting soil, making sure to replace it (when doing these tests, be gentle and put things back the way they were).

Whatever tree you buy and however it was grown, when you get it home, dig a ten dollar hole for a five dollar tree, but don’t overdo it or the tree will never try to extend its roots beyond the hole. Give it a little compost in the backfill and keep a light hand on the fertilizer. Water deeply and mulch lightly, and don’t pile the mulch up against the trunk, no matter how many “professional” landscapers you’ve seen do it! For as long as you take care of your tree, keep grass and other plants at least several feet away from the trunk, which will not only reduce competition for water and nutrients, but eliminate the possibility of mechanical damage from mowers and trimmers. Planting the right tree for your location will help reduce its need for extra water as it matures, though when absolutely necessary in the hottest, driest part of the summer, by all means give it water if you can. In time, your tree will reward you or someone in the future with cool relief from summer heat.

Let It Go

 

Following on the heels of the news story about Internet Service Providers (ISPs) astroturfing the Federal Communications Commission (FCC) to influence its decision on rolling back net neutrality regulations, and in some cases preceding it by several years, is the revelation that Monsanto, makers of Roundup herbicide and a world leader in producing genetically modified seeds, has allegedly been paying shills to post positive comments online about the company and its products, particularly on websites which portray them negatively. Even more disturbing has been the information from internal company memos which reveal its strategy for tilting scientific opinion in its favor by funding biased think tanks, funneling grant money to friendly scientists and academic institutions and even ghost writing papers for them, all of which are meant to appear as impartial efforts, while debunking contrary news articles and impugning the motives of the journalists who write them. Monsanto refers to its policy as “Let Nothing Go”.
Monsanto-siembra-muerte.B.A.2013
Anti-Monsanto stencil “Monsanto – Siembra Muerte” in Buenos Aires, Argentina, in 2013 reads in English “Monsanto – Seeds of Death”; photo by JanManu. Monsanto’s policies and practices have engendered large scale protests in Argentina, as well as elsewhere around the world. Strangely, in the United States, the land where Freedom of the Press is enshrined in the First Amendment to the Constitution, the mainstream media is largely silent about agribusiness misconduct. Test that yourself with an internet search.

 

Monsanto is not alone among companies in tasking their public relations people with promoting a positive image online in comments sections, forums, and social media. That’s a very good reason for taking such comments with a large grain of salt. It’s akin to what you may hear around the water cooler at work, only in this case one or more of your fellow gossips makes oddly stilted remarks in favor of the company way, as if speaking from a script. When one of those gossips dons a white laboratory coat and purports to speak with scientific authority on the subject at hand, the discussion moves magically from around the water cooler to around the executive conference table. There the discussion is not so much about influencing public opinion as it is about setting the parameters for debate and ultimately public policy.

Robert Morse learns under the tutelage of mail room boss Sammy Smith as they sing “The Company Way” in the 1967 movie of How to Succeed in Business Without Really Trying.

However, just because a shill wears a lab coat and has a list of academic degrees behind his or her name does not make that person any less of a shill than the one who makes a few dollars trolling comments sections on behalf of a corporation. The scientific high priest type of shill is morally worse because he or she exploits the respect and gullibility of the general public when hearing pronouncements from them. Not all of the science shills know what they do, of course, because they may be true believers. The others, who know what they do, but go on anyway because of greed and ambition, deserve no leeway from the public or their peers, and more likely deserve condemnation. Jesus knew as much when He denounced the Pharisees.

A scene from the 1970 movie Little Big Man, with Dustin Hoffman and Martin Balsam. Snake Oil Salesmen and their Shills by no means disappeared with the 19th Century.

For whatever topic you care to name that puts at risk the finances of large corporations – tobacco, climate change, Genetically Modified Organisms (GMOs) and the herbicides that accompany them – you can find a corporate funded think tank with outreach to a handful of friendly scientists and institutions who scramble to debunk legitimate research and hold back a growing avalanche of negative public opinion. The agribusiness funded Genetic Literacy Project has nothing good to say about U.S. Right to Know, an organization largely funded by the organic food industry. Similarly, U.S. Right to Know dismisses the science of the Genetic Literacy Project. The organic food industry in the United States has about 5% of the market and is steadily growing year after year. Organic foods are by definition non-GMO. You are free to make up your own mind about who to believe, of course, and it’s a good thing then that to help you decide, many sellers of non-GMO foods have begun labeling their products as such. This was after giant agribusinesses successfully lobbied the government to scuttle labeling of products that do contain GMO foods. The big corporations apparently don’t trust you with the facts and with making decisions for yourself based on those facts.

Cool, Clear Water

 

The ongoing dispute that Energy Transfer Partners, in cooperation with the federal government, is having with several Native American tribes over the Dakota Access Pipeline section that crosses the Standing Rock Indian Reservation in North Dakota brings up questions about water and its importance to everyday existence. Obviously clean water is essential to life, which is apparently why the Army Corps of Engineers moved the original path of the pipeline from north of Bismarck, North Dakota, where it would threaten the integrity of water supplies there should the pipeline fail and leak oil. How is clean water then less essential to life on the Standing Rock Indian Reservation south of Bismarck, because that is where they relocated the pipeline? Besides the issue of trespassing on sacred grounds on the Reservation, there is the elemental matter of maintaining the integrity of clean water for the Reservation’s animal and human inhabitants.

The Sons of the Pioneers were the first to perform this song written by one of their own, Bob Nolan, in the 1930s, and since then other artists have covered it dozens of times.
The Dakota Access Pipeline stretches from the oil shale fields of northwest North Dakota to an oil tank farm in southern Illinois, crossing much privately owned farmland along the way. The controversial use of eminent domain to gain access for a privately owned corporate partnership is another subject. The issue at hand here is how the elders of Standing Rock Indian Reservation, which technically speaking in the language of treaties with the federal government represent the interests of a sovereign nation within the borders of the United States, can fend off this challenge to their land and their water. Does the federal use of eminent domain apply in their case? The common sense answer would be “no.” History has shown, however, that the “sovereign nation” bit in treaties between the United States and Native American tribes was a mere sop not worth the paper it was written on, and intended only to placate the tribes until such time as we needed their land for one reason or another. All bets were off then, and might made right. That’s what the current controversy comes down to, and after a brief stay from the Obama adminstration in continuing construction of the pipeline across Indian land, the new administration under Supreme Leader has weighed in with a sadly predictable decision.

 

Since the 1980s, when bottled water first started showing up in quantity in supermarkets in the United States, Americans seem to have taken for granted the rare and precious resource that is clean water. Particularly in the eastern half of the country, where (Flint, Michigan aside) municipal water supplies have been plentiful and largely free of problems, Americans have become deluded by the strange idea that the water coming out of their taps was somehow deficient and that the bottled water they bought from the supermarket was better. At first, due to the aura of prestige surrounding European bottled water brands like Perrier and Evian, people bought and sipped bottled water as a matter of status. Eventually it became just a thing to do. This proved to be a type of madness, particularly after the water in bottles proved to be no better, and in some cases worse, than the water coming out of most people’s taps, at least in the eastern half of the United States. People in the western half of the country often have had to cope with tap water that was  unacceptably hard, and have had more reason therefore to turn to bottled water.


The Washita River Massacre portrayed in the 1970 film Little Big Man. Anti-war and anti-government sentiment of the time influenced this film, but its portrayal of Native Americans and their distressing relationship to their conquerors was a welcome corrective after decades of stilted, one-sided inaccuracies in Hollywood movies. The tune is “Garry Owen”, an Irish quickstep adapted as the marching song for Custer’s 7th Cavalry.

 


“You don’t know what you’ve got ’til it’s gone.” ― Joni Mitchell
In some cases, buying and consuming commercially produced distilled water, even in the United States, the land of mostly wholesome public drinking water compared to much of the rest of the world, is not a bad idea. Other than that, the idea of giving international conglomerates like Nestlé and Coca-Cola more money and control over water supplies, a resource far more precious than oil, is foolish and insane. The Native American protesters and their supporters at Standing Rock have the sane and sagacious idea of protecting the water that courses through the Reservation, and considering the vital importance of that resource the rest of us had best pay attention now because it will flow our way in time.

Salting the Earth

 

“Carthago delenda est!” [Carthage must be destroyed!] ― Cato the Elder

 

The National Weather Service has forecast an ice storm for the central United States this weekend. Road crews will most likely treat the roads with a brine solution before the storm arrives, and in case ice accumulates nevertheless, they will return to treat the roads with rock salt, sand, and possibly other materials to increase traction for motor vehicles and rid the roads of ice. What happens to all that salt after the storm, and how does it affect roadside plants, soil, and the water table?

Some of the salt dilutes with water from the ice and atomizes into droplets that passing vehicles spray onto roadside plants. The damage can most easily be seen in early spring as plants and trees sprout new foliage which may suffer from scorching on the side that received the salt spray. Most of the salt runs off into the soil and the water table near the road, where it can cause a number of problems, including interfering with water uptake by plants and contaminating residential and agricultural wells. Some salt migrates into city water supplies.
Excessive salt has long been known as a detriment to agriculture. Plants show little need for salt, while animals can’t live without it. Our word “salary” is rooted in the Latin term for salt, which indicates its crucial importance to everyday life for people. It’s ironic then that poor fertilization and irrigation practices can lead to the salinization and ultimate abandonment of agricultural land. With population growth come more roads and development into the countryside, taking over or abutting traditionally agricultural land, and consequently adding more salt to the environment.

Salt from Berchtesgaden

Some localities across the nation have been experimenting with alternatives to use of rock salt exclusively, such as mixing in cheese brine, beet juice, or sugarcane molasses. Whether or not these alternatives ultimately prove as effective as rock salt and comparable in cost, for auto drivers who need to get out and about in an ice storm personal safety understandably comes first and environmental effects second, or even third after reckoning the tax bill for materials and labor. Considering all that, we might reflect how Cato the Elder’s oft invoked exhortation to vanquish the Carthaginians at any cost led after many years to civil war and then to the dubious distinction of empire, and we might then note how a relentless quest for domination of our perceived foes, in nature or otherwise, as often as not has unintended consequences and unfortunate side effects for ourselves.
