[URBAN NOTE] "Why Toronto’s Urban Forest is a Critical Infrastructure Asset"

2016-12-08T01:27:40Z

In a sponsored post, Torontoist's Catherine McIntyre looks at the importance of Toronto's urban forest as a source of financial and other benefits.

When a resident from Kleinburg, a heritage district in York Region, proposed a plan to build an underground garage on his property, the City signed off with little dispute. The car park, complete with a hydraulic lift, would be close to the property line, but would offer just enough clearance from the neighbour’s mature trees to avoid causing any damage. Soon after the resident started excavating, however, the City was inundated with calls from a frantic neighbour. Major roots that stretched from their property into the excavation area were severed, cutting off a significant means of water and nutrient uptake, and the neighbour feared, correctly, that their trees would die.

It turns out the resident building the garage had mislead the City by submitting plans for the above-ground area of the project—a fraction of what was being excavated below the surface.

But according to Philip Van Wassenaer, a seasoned arborist and tree consultant for municipalities, knowing the construction would have damaged the roots wouldn’t have mattered anyway. “What’s below ground—40 to 50 per cent of the tree’s biomass—is the most important part,” says Van Wassenaer, “But if my tree is growing a metre away from the property line and you get permission to excavate to that point, then you’re going to be doing significant damage to a portion of the roots in my tree, and I have no recourse.”

Indeed, while municipalities have the mandate to protect the trunks, branches, and leaves of mature trees, the vital root systems remain largely ignored by policy, leaving them vulnerable to development.

It’s just one of the many limitations in the efforts to protect the GTA’s urban forest—a critical asset for healthy cities, and one that is increasingly under threat, from climate change, disease, and the built environment.

[URBAN NOTE] "How to Fight Against the Devastating Emerald Ash Borer"

2016-05-17T22:21:51Z

Torontoist's Ryan O'Connor reports on terrible ecological news for Toronto.

The emerald ash borer is an invasive species of beetles first spotted in North America in 2002. Since then the metallic-green insect has destroyed tens of millions of ash trees across the continent. When it was detected in Toronto in 2007, its devastating effects were widely known. Simply put, once the emerald ash borer takes root in a locale, it is nearly impossible to stop its spread, and the subsequent destruction of the entire ash tree population.

According to a study undertaken by the City of Toronto’s Urban Forestry department, there were 860,000 ash trees at the time of the infestation, with approximately 40 per cent located on public land. The City implemented a mitigation and replacement strategy to limit the damage, including planting new trees and using an injection to protect existing ash trees. The injections, which use the insecticide TreeAzin, manage to protect the trees from the emerald ash borer, but must be reapplied on an annual basis. As of the end of 2015, there were 11,479 trees located on public lands that had received these life-sustaining injections, while 48,400 ash trees have been removed by Urban Forestry. Although there are no firm figures available for ash trees located on private property, Sarah Doucette (Ward 13, Parkdale-High Park), Council’s tree advocate, estimates that just 300,000 remain in the city. This number will continue to dwindle, with all but the injected ash expected to be dead by 2020.

[LINK] On the bonsai tree that survived the atomic bombing of Hiroshima

2015-08-06T19:30:56Z

The National Post carried Faiz Siddiqui's Washington Post article describing a bonsai tree now nearly four centuries old that survived 1945.

Moses Weisberg was walking his bicycle through the National Arboretum in Northeast Washington when he stopped at a mushroom-shaped tree. The first thing he noticed was the thickness of the trunk, estimated at almost a foot and a half in diameter. And then there was the abundance of spindly leaves, a healthy head of hair for a botanical relic 390 years old.

But it was only when he learned the full history of the tree, a Japanese white pine donated in 1976, that he was truly stunned. The tree, a part of the Arboretum’s National Bonsai and Penjing Museum, has not only navigated the perils of age to become the collection’s oldest; it survived the blast of an atomic bomb, Little Boy, dropped over Hiroshima, Japan, during the Second World War.

“For one, it’s amazing to think that something could have survived an atomic blast,” said Weisberg, a 26-year-old student at the Georgetown University Law Center. “And then that by some happenstance a Japanese tree from the 1600s ended up here.”

The bonsai tree’s history is being honoured this week, as Thursday marks the 70th anniversary of the Hiroshima bombing. But visitors can see the tree as part of the museum’s permanent collection throughout the year.

The tree, donated by a bonsai master named Masaru Yamaki, was part of a 53-specimen gift to the United States for its 1976 bicentennial. Little was known about the tree until March 8, 2001, when — with no advance notice — two brothers visiting from Japan showed up at the museum to check on their grandfather’s tree.

[URBAN NOTE] On how Torontonians (and other humans) benefit from trees

2015-07-15T18:49:46Z

A post on Discover magazine's Inkfish blog alerted me to some interesting research.

What’s a tree worth to you? According to a large study in Toronto, trees may increase both how healthy you feel and how healthy you really are. Having some extra foliage on your block could be as good for your health as a pay raise–or an anti-aging machine.

It’s a complicated relationship to figure out, because variables that affect how many trees you see each day could also affect your health. The population of a concrete, inner-city apartment complex may have socioeconomic differences, for example, from the population of a leafy, well-tended suburb. University of Chicago psychologist Marc Berman and his colleagues used a detailed analysis to try to tease out the impact of trees themselves.

They started by going to Canada. In a country with universal health care, they figured, access to doctors isn’t as much of a variable as in the United States. Since socioeconomic status can still affect how people use doctors, the authors also gathered information on their subjects’ income and education. And rather than comparing people from multiple areas, they focused only on the city of Toronto.

From a large-scale, ongoing project called the Ontario Health Study, the authors collected data on over 31,000 adult residents of Toronto. In addition to household income and years of education, they looked at subjects’ sex, diet (self-reported servings of fruits and vegetables per day), and neighborhood. The Ontario Health Study questionnaires also asked subjects whether they’d ever been diagnosed with various physical and mental health conditions.

The final measurement was health perception: how healthy do subjects feel they are, on a scale from 1 to 5? It sounds vague, but this measurement has been found to strongly predict actual health, the authors write.

The Toronto Star's Geoffrey Vendeville went into more detail.

Using data from Toronto, a team of researchers has found that having 10 more trees on your block has self-reported health benefits akin to a $10,000 salary raise or moving to a neighbourhood with a $10,000 higher median income or being seven years younger.

By comparing satellite imagery of Toronto, an inventory of trees on public land and general health surveys, the team, led by University of Chicago psychologist Marc Berman, found that people who live on a tree-lined block are less likely to report conditions such as high blood pressure, obesity, heart disease or diabetes.

Their findings appeared last week in the open-access journal Scientific Reports.

The study suggests “pretty strongly” that planting 4 per cent more trees would have significant health benefits, Berman said.

Researchers don’t know why, exactly, trees seem to be good for people’s health.

“Is it that the trees are cleaning the air? Is it that the trees are encouraging people to go outside and exercise more? Or is it their esthetic beauty? We need to understand that,” he said.
