Devastation looms: Mountain pine beetle threatens industry, U of A study
reveals

EDMONTON - A University of Alberta school of business study on the
mountain pine beetle presents a doomsday scenario of vast tracts of dead
forest, falling trees and massive forest-fire hazards.
The 42-page research paper, Managing the Economic Impacts of the
Mountain Pine Beetle Outbreaks in Alberta, says that if the pestilence
rivals the damage in B.C., there would not be enough milling capacity in
Alberta to process all of the infested timber.
U of A business dean Mike Percy said the study is aimed at policy-makers
in government, forestry educators and decision-makers in business. The
numbers, he says, give credence to the concerns of groups that have been
saying it raises a significant threat to the viability of the forest
industry.

are resequencing their harvesting to account for the invasion of

One report cited in the study says that within five years, beetle-killed
stands start falling over, with up to 50 per cent of trees fallen within
nine years and 90 per cent knocked down after 14 years.
"In general, MPB-attacked stands have the potential for greater
ground-level fine and coarse woody fuel volumes, which can significantly
alter forest fire behaviour and increase the fire hazard within the
stand," says Percy.
Plus, the study says further major outbreaks would create significant
shortages of forest workers and equipment, further limiting harvesting
and utilization of beetle wood.
The paper utilizes the Foothills Model Forest near Jasper for a case study.
"It likely, significantly, underestimates the impact of mountain pine
beetle," says Percy, of relatively low infestation rates of seven to
nine per cent of trees in the model forest.
The report also extrapolates data on the beetle's path of destruction
through B.C. forests which has seen nine million hectares destroyed.
Scientists predict that 80 per cent of B.C.'s pine forests will be lost
to the bug by 2013.
"This needs a degree of co-ordination between provinces and the federal
government. It needs the environmental community as well to be engaged.
When you look at the range of stakeholders you need singing from the
same song sheet, it's a pretty formidable exercise."
The study was completed by Blake Phillips, James Beck Jr. and Trevor
Nickel of the U of A's Western Centre for Economic Research.
The paper says that industry would initially benefit from a surge of
timber flowing through mills. But the resulting lumber would flood
markets and have an impact on prices. "There would be a surge of timber
onto the market. In a sense, it would be as if now, in effect, we are
mining the forest," Percy said.
Plus, there could be an extended period of 171 to 190 years required for
forests to fully regenerate their lost volumes.
If unchecked, some authorities forecast the pine beetle will ravage the
northern boreal forest clear across the country to Labrador in years to
come.
The study says that beyond economic and forestry industry capacity
issues, there are a myriad of social and environmental issues which need
to be balanced in any large-scale plan to manage the pest.
Late last year, provincial officials found more than two million Alberta
lodgepole pines were infected in the foothills stretching from north of
Grande Prairie to south of Grande Cache. There is another outbreak along
the Eastern Slopes near Canmore.
More than $23 billion of commercial timber is at risk. Billions of pine
beetles, each the size of a grain of rice, were carried across the
Rockies in the jet stream last summer. The beetles burrow beneath the
bark, feed and lay eggs in mature trees. They often exist at endemic
levels, but in great numbers kill trees. They also infect a tree with a
blue-tinged fungus that eventually proves fatal.
Alberta has so far sunk about $27 million into efforts to contain the pest.
