HALIFAX — An invasive insect from Asia is expected to kill almost every ash tree in Canada, but Donnie McPhee has a plan to preserve the species.
Co-ordinator for the National Tree Seed Centre in Fredericton, McPhee is asking Canadians to help him find mature stands where seeds can be gathered and later stored for future generations in the centre’s deep-freeze vaults.
“We’re looking to protect the genetic diversity of the species,” McPhee said in an interview. “We’re looking for natural stands of trees that are in seed …. We want Canadians to be our eyes — to let us know they’re out there.”
And the time is right to start the search because the white ash and black ash — two of the most common species — are expected to produce a bumper crop of seeds this fall. The centre’s website provides details on what to look for, but seed collecting should be left to experts.
“We’ve already had people showing up with big bags of ash seed … but it’s too early in the season,” McPhee said.
Larvae of the emerald ash borer, a small beetle with an iridescent green hue, have already killed millions of trees in Canada and the United States, and the pest’s population is still growing.
The larvae make tunnels underneath the tree’s bark, cutting off nutrient flow to the canopy, which eventually kills the tree.
“The reports I’ve seen suggest that within 50 years, there might not be any ash trees anywhere in the country,” McPhee said.
McPhee’s long-term plan is to have the centre retrieve the collected ash seeds from cold storage in about 40 or 50 years, when the ash borer population has dwindled and safe planting can begin.
“The population of the insect will drop way down because the food supply isn’t there,” he said. “At that time, we want to go in and put the genetic diversity of the population back to where it came from.”

North America is on the cusp of a mass timber revolution, and the Waterfront Toronto project is leading the way. But the material faces major obstacles.
Abuilding made primarily of wood conjures public fear of fire, but for a growing number of developers, it evokes opportunity. From constructing towering wooden condominiums, to timber college dormitories, to an entire neighborhood built from trees, experts in “mass timber” are creating buildings of the future.
Sidewalk Labs’ master plan for a futuristic smart city on the waterfront in Toronto includes an entire neighborhood made of wood, called Quayside, with 10 mixed-use building up to 35 stories.
The plan is audacious, considering that in the U.S., there are only 221 mass timber buildings in the works or fully built, according to the American Wood Council’s Kenneth Bland.
In most U.S. cities, mass timber buildings, and specifically tall mass timber buildings, are a rarity, if they exist at all.
But architects, city officials and timber advocates across North America are pushing conventional building codes and public perception because of the drastic impact these structures can have on reducing CO2 through carbon sequestration, compared to traditional concrete and steel.
“I think it’s a big opportunity for a lot of cities out there … The impact on reducing carbon emissions on earth could be dramatic,” Karim Khalifa, director of buildings innovation at Sidewalk Labs, told Smart Cities Dive. “And that gets me excited.”
What is mass timber?
One of the biggest obstacles for city officials is understanding the material. They are more than buildings made of wood — they’re defined by their structure. Steel or concrete buildings with wood accents don’t count, according to Andrew Tsay Jacobs from architecture firm Perkins and Will.
Mass timber buildings use solid wood panels to frame a building’s walls, floors and roofs, creating structures that can reach at least 18 stories, as is the case with the tallest mass timber building in the world in Norway. But these buildings aren’t just pure wood. Mass timber construction utilizes engineered wood, or panels glued together, and there are several types: cross-laminated (CLT), glue-laminated and dowel-laminated timber, with CLT being the most common.
While shorter wood buildings have existed for centuries, CLT panel technology is relatively new. It was developed in Europe in the 1990s, the material was only added to the international building code in 2015. Even then, all-wood buildings were capped at six stories, though that will change to allow taller structures in 2021.

The U.S. timber industry scored a win on April 9 in the decades-long battle with Canada over softwood lumber, after the World Trade Organization ruled in its favor.
On April 9, the WTO decided that the United States Department of Commerce had done the correct calculations when it determined anti-dumping duties on Canadian softwood lumber.
“It’s a victory for the United States and the forest products industry,” said Chuck Roady, general manager of F.H. Stoltze Land and Lumber, as well as the president of the Montana Wood Products Association. “It was great to see an excellent decision on our part, because the U.S. rarely prevails in the WTO.”
Softwood lumber has been the subject of an enduring trade dispute between the two countries, and the most recent Softwood Lumber Agreement (SLA) lapsed in 2016 after 10 years.
The roots of the dispute come down to two different forms of government having two different methods of lumber harvest. Canada’s provincial government owns the majority of timberlands that provide trees to Canadian producers, charging an administered fee. In the U.S., the timberlands are typically privately owned, and the market determines the price of those logs through public sales.
“Both systems work until you sell the lumber in the United States,” Roady said.
In November 2017, the U.S. Commerce Department determined that Canadian exporters had sold lumber in the U.S. for 3.2 percent to 8.9 percent under fair market value, and that Canada is subsidizing softwood lumber producers at rates of 3.34 percent to 18.19 percent. The department determined that Canadian lumber producers should then pay a combined tariff of 20.83 percent.
In its mixed ruling on April 9, the WTO determined that the U.S. use of “zeroing” to calculate the anti-dumping duties is not prohibited. In the past, the organization had ruled against the methodology.
The ruling also determined that the U.S. had violated international trade rules when it calculated the tariffs on softwood lumber imports, which Canada applauded.

Lands and Forestry Minister Iain Rankin is promising “significant” changes to the province’s forestry sector as the government embraces more sustainable management. But critics say the government’s plan lacks important detail.
Lands and Forestry Minister Iain Rankin is promising a more sustainable forestry sector in Nova Scotia and less clear cutting as the province implements recommendations from the Lahey review of forestry practices, although how big that reduction will be remains to be seen.
The government’s long-awaited response to the report was released Monday and received positive reactions from critics and industry, though some said the province’s plan was short on detail.
“Forestry is a long-standing economic driver in Nova Scotia and it’s important we get it right,” Rankin said in a news release.
“We accept Prof. Lahey’s findings and will immediately begin work to put in place the tools to achieve ecological forestry in Nova Scotia. This will result in significant changes to the way forests will be managed, including less clear cutting on Crown land.”
Bill Lahey, the president of University of King’s College, presented his final report in August.
The predominant theme of the report was reducing clear cutting to 20 to 25 per cent of all harvesting on Crown land from 65 per cent.
The report recommended using a “triad model” that would see some areas used for intensive commercial forestry, some protected from all commercial activity, and some designated for less intensive forestry with little to no clear cutting.
A forester from Bancroft, Ont., says the province could be doing much more to deal with an insidious disease that’s killing beech trees across Ontario.
Svetlana Zeran called in to CBC’s Ontario Today Monday to say beech bark disease is a major concern on the nearly 400,000 hectares of forest her company manages.
“We have been dealing with beech bark disease for about a decade,” Zeran said. “Now that it is here on the [Canadian] Shield, it is moving very rapidly and we are seeing the disease come in and infect the trees and they are dead within two to five years.”
The disease begins when an insect bores holes in the bark, allowing a red fungus to invade the tree and slowly weaken it from the inside out.
The State of Canada’s Forests Annual Report provides a national snap shot of Canada’s forests and forest industry. We’ve been tracking our journey toward sustainable forest management for 28 years. This year’s report focuses on the theme “faces of forestry” and features the innovative ways people work and learn in forests.

A new tower will have greenery lining the balconies and roofs to clean up the air and provide a new environment for pollinators and humans alike.
Toronto has long been serious about its urban canopy. The Ontario city is already home to around 10 million trees, which cover around 26% of the city. The current mayor, John Tory, wants to grow that to 40%.
Brisbin Brook Beynon, a local architecture firm, is already giving the city a leg up on that goal, albeit in an unconventional way: a 27-story residential building that will be covered with around 450 trees, growing on its balconies and roofs. This “vertical forest,” as BBB terms it, takes inspiration from the Bosco Verticale–residential towers in Milan that went up in 2014 with as many as 11,000 plants lining the sides. Since then, copycat buildings have been built in cities like Nanjing and in Taiwan–designed to combat pollution and prove that green space does not need to be limited to the ground. This latest iteration could open as early as later next year.
For Brian Brisbin, principal at BBB, bringing the vertical forest concept to Toronto aligned perfectly with the mayor’s goals for increasing tree coverage. And when he began researching the concept by studying the Bosco Verticale, he realized that all of the technology that enabled the Milanese building to function originated in Canada and North America. “That felt fairly profound,” Brisbin says.
And it also, Brisbin says, made bringing the concept to Toronto feel much more feasible. “We have a lot of depth of specialty in this area in Toronto, with horticultural and agricultural universities and research facilities,” he says, “and we’ve brought a lot of together to take a very science-based approach to developing this project.”
State and federal entomologists believed the destructive pest would show up near the New Hampshire border, not hundreds of miles to the north.

A massive and uncontrollable buildup of mountain pine beetles in Jasper National Park is starting to explode into commercially valuable forests along its boundaries.
Foresters along the park’s edge have seen a tenfold increase in beetle infestation in just months, and some scientists wonder if Parks Canada could have done more to control the invasion a few years ago.
“They decided to consider the pine beetle a ‘native disturbance agent,”‘ said Allan Carroll, who has studied the beetles since the late 1990s and directs the University of British Columbia’s Forest Science program. “In other words, Jasper was not intending to do much about it.”
No end to pine beetle battle in Alberta, experts say
In an emailed statement, Parks Canada said it has had a beetle management plan for the park since 2015 that includes prescribed burns and tree removal.
Too little, too late, said Carroll.
“Just that hesitation intrinsic to producing a management plan precluded any effective outcomes.”

The Trump administration announced on Monday it is planning to impose a roughly 20 percent tariff on softwood lumber imported from Canada, in what may be the biggest trade dispute between the U.S. and Canada in over a decade.
The Obama administration began the review of trade in softwood lumber last year out of concern that Canada was subsidizing its wood industry in a way that hurt U.S. rivals. The decision to impose what are known as “countervailing duties” in retaliation for Canada’s wood subsidies, which will be announced Tuesday, is subject to a final review by the International Trade Commission, an independent federal agency that advises the government on trade policy.
The decision, however, allows U.S. Customs and Border Protection to begin collecting the funds from Canadian importers immediately. Five Canadian companies were a part of the investigation, and the United States will seek to collect money from four of them retroactively for actions taken in the past 90 days, Ross said.
Ross said this could amount to $1 billion in new tariffs, as well as $250 million in retroactive collections. All other Canadian softwood lumber companies will face the same tariff of 19.88 percent going forward.
Softwood lumber is a major export of Canada, which sold $5.8 billion in lumber to the United States last year, giving it about 31.5 percent of the U.S. market. It’s the fourth largest export from Canada to the United States after oil, gas and cars.
