Forestry ex­perts await in­va­sive bug

The Guardian (Charlottetown) - - ATLANTIC -

HAL­I­FAX — Forestry ex­perts in At­lantic Canada are get­ting ready for the ar­rival of a new, in­va­sive species that has de­stroyed mil­lions of ash trees in other parts of Canada.

The Emer­ald Ash Borer is a non-na­tive pest from Asia that was first in­tro­duced in Canada and the United States in 2002, and is now mak­ing its way to Nova Sco­tia.

An­drew Wil­liams, the ur­ban forestry co-or­di­na­tor for the Town of Truro, says the bug is east of Mon­treal and only a day’s drive from At­lantic Canada but that they are mon­i­tor­ing for it with traps in the com­mu­nity. Ex­perts say lar­vae feed be­neath the bark of ash trees — cut­ting off their abil­ity to move wa­ter and nutri­ents, and even­tu­ally killing them. He says that once an ash tree is in­fected, it is lost within three years.

Wil­liams tells Global News that the pest could elim­i­nate ash from North Amer­ica, par­tic­u­larly since there are no nat­u­ral preda­tors or dis­eases to keep pop­u­la­tions in check.
