Mountain Pine Beetle

Mountain Pine Beetle

The mountain pine beetle (MPB) Dendroctonus ponderosae, is a species of bark beetle native to the forests of western North America from Mexico to central British Columbia. It has a hard black exoskeleton, and measures about 5 mm, about the size of a grain of rice.

Mountain pine beetles inhabit ponderosa, lodgepole, Scotch and limber pine trees. Normally, these insects play an important role in the life of a forest, attacking old or weakened trees, and speeding development of a younger forest. However, unusual hot, dry summers and mild winters in central British Columbia during the last few years, along with forests filled with mature lodgepole pine, have led to an unprecedented epidemic.

It may be the largest forest insect blight ever seen in North America. Climate change is said by some to have contributed to the size and severity of the outbreak, and the outbreak itself may, with similar infestations, have significant effects on the capability of northern forests to remove greenhouse gas (CO2) from the atmosphere.

Famous quotes containing the words mountain, pine and/or beetle:

    “There is a mountain in the distant West
    That, sun-defying, in its deep ravines
    Displays a cross of snow upon its side.
    Such is the cross I wear upon my breast
    These eighteen years, through all the changing scenes
    And seasons, changeless since the day she died.”
    —Henry Wadsworth Longfellow (1809–1882)

    “Before I finally went into winter quarters in November, I used to resort to the north- east side of Walden, which the sun, reflected from the pitch pine woods and the stony shore, made the fireside of the pond; it is so much pleasanter and wholesomer to be warmed by the sun while you can be, than by an artificial fire. I thus warmed myself by the still glowing embers which the summer, like a departed hunter, had left.”
    —Henry David Thoreau (1817–1862)

    “Ere the bat hath flown
    His cloistered flight, ere to black Hecate’s summons
    The shard-born beetle with his drowsy hums
    Hath rung night’s yawning peal, there shall be done
    A deed of dreadful note.”
    —William Shakespeare (1564–1616)
