The timber, which is of great economic value of Canada, threatened by acid precipitation, damage from insect pets, and forest fires.
Acid Precipitation
One of the serious problem for the forests of eastern Canada is
an Acid Precipitation. It caused by emissions from
factories in the industrial areas of eastern Canada and eastern United States,
harms the canopy as well as the soil.Those that do not die outright grow much more slowly. The maple syrup-producing forestd south of Quebec
Ciry have espiecially suffered from acid precipitation.
Insects Pests
Insect Pests
and Diseasesa rea damaged is larger than annual harvest by forest
companies. Ââmportedâinsect pests (foreign species) in order to prevent
spreading,Âsusceptible species are removed. The spruce budworm, tent
caterpillar, and gypsy moth in eastern Canada, and the pine bark ettle in
British Columbia, cause millions of dollars of damage to forests every
year.
Forestry companies and
provincial governments spend a great deal of time and money trying to
control these insects and diseases so they will not spread
Forest Fire
Fire occurs in
forests, shrub lands and grasslands. Some are uncontrolled wildfires
started by lightning or human carelessness.
Forest fire caused by
48% of lightning, fairly remote areas, and 52% of people near settled
areas.
Wild land fires
present a challenge for forest management because they have the potential
to be at once harmful and beneficial.
Not all wild land
fires should be controlled. Forest agencies work to harness the force of
natural fire to take advantage of its ecological benefits while at the
same time limiting its potential damage and costs.
This makes fire
control strategies a vital component of forest management and emergency
management in Canada.
