The first video shows each step in the proper planting of a tree. Eric Vorodi, a certified arborist in Pennsylvania, explains in professional detail the reasons behind each step.
The demonstration is remarkably similar to one performed by Kevin Steed, Town of Cary Arborist, who showed and narrated the proper way to plant as he put a tree in the ground by the police station at a Arbor Day celebration a few years ago. Unfortunately, Mr. Steed's demonstration was not filmed. Had it been filmed, I would have asked his permission to use it. Mr. Vorodi's demo is the most detailed I could find that has been filmed. Again unfortunately, the quality of the video is not good. Mr. Vorodi speaks as he works, which results in a lot of dead air. I cut much of that and also speeded up the video to 133%. This makes his voice sound very high. But it's not unbearable, and the reasons he gives for what to do and (perhaps more importantly, what not to do) are critical if a tree is to survive and thrive.
This video shows a way to salvage an improperly planted and nurtured tree.
Whether a tree lives or dies is not a major concern for most of us. It is when the whole population of trees decreases to a level that affects our health and the health of our loved ones that we grow concerned.
The human population of Cary increases by 8.3 persons per day. The rate of car ownership in the U.S. is, each person owns .715 cars. Thus the vehicle population of Cary increases on average by about 5.9 cars per day.
Cary uses about 440 acres per year for development. If we conservatively estimate there are 100 trees on the average Cary undeveloped acre, that means 44,000 trees are cut down each year, which works out to about 120 trees lost per day.
On average, each car exhausts 7.5 tons of carbon dioxide and other pollutants into the air every year. An average mature tree can convert about 50 pounds of carbon dioxide to oxygen (and other un-harmful chemicals and substances) each year. [Of things that pull pollution from the air, trees pull 98%.] Therefore, for each vehicle in Cary, there should be 300 trees — if our goal is to maintain our atmosphere at its present polluted condition. If we wish to begin to actually clean our air, then there must be more than 300 trees per vehicle.
We will all of us make the decision whether the time and expense of salvaging the tens of thousands of trees in Cary planted this way is worth it. My opinion and position is that it is not only worthwhile, but critically important. The rate of incidence of childhood asthma and other bronchial diseases is skyrocketing. The rate of cardiovascular and pulmonary diseases in the older population is increasing dramatically. Studies have shown that the rate of incidence of these diseases — and the mortality therefrom — is both predictable, because of the loss of trees, and proportional to the number of trees lost.
When the number of cars in a Town goes up, and the number of trees in that Town goes down — and this process inexorably continues day by day, month by month, and year by year — it doesn't require genius to understand why pollution increases.
