Hello ...I posted 4 photos seen here of a Skotch pine tree. I then have
three photos of trunk infestation. I live in Southern Saskatchewan Canada
(close to the montanna border) . The tree apears very healthy, however the
holes in the tree have me concerned... Any ideas on what this is and how to
combat it would be a great help. Thank you all for any positive responses..

Here are the photos:
