Save Our Trees!  OR ELSE!
Lifespan of common urban trees

CBC News Online | August 11, 2005

Not all trees are created equal when it comes to life in the city, says Ken Farr, a tree expert with the Canadian Forest Service.

As a general rule, there are more species of long-lived broadleaf trees than conifers. But don’t rush out to plant that gorgeous Canadian icon, the sugar maple, if you want your great grandchildren to see it.

“Sugar maples don’t like growing in the city. They never have. They don’t like compacted soil. They also don’t tolerate pollution very well,” says Farr.

White birch is another esthetically pleasing tree that evokes nationalistic feeling, but like the sugar maple, can’t stand the city. “They’re highly susceptible to summer drought, they don’t like pollution and they’re a real target for boring insects,” says Farr.

One more no-no for city planting is the eastern white pine, the official tree of Ontario. During colonial times, these majestic trees were logged and floated down the Ottawa River, destined for the masts of English ships.

Today, no urban forester would chose the eastern white pine for street planting because of its intolerance to road salt.

“If you live in eastern Canada where they throw salt around like popcorn, you grow the Austrian and Scotch pine. They are non-native European species that have a good tolerance for salt,” says Farr.

So without further delay, we offer here some of the more common trees grown in Canada’s cities and towns, and their expected lifespan (trees in a natural setting have longer lifespans):

Is this good government?

The fact of the matter is this:

Trees do have a specific life cycle that is impacted by their environment.

Trees are prolific enough to cover all of Niagara in 1 or 2 human generations!

Trees are not an endangered species!

Governments threaten their citizens with fines and waste valuable production time on the absurd excuse that they are concerned about trees!

Sadly it would appear that the ONLY thing our regime is concerned about is money!

Our regime is willing to abandon hectares of Carolinian forests before providing access for firefighters! They are quite willing to remove access with little regard to the welfare of trees!

Our regime employs any and all means to financially abuse its citizens! Feigning concern for trees is just one of them!
