Pine Beetles in the Colorado Rockies

Thanks Jenifer for some great research on Pine Beetles:



Dear Friends,
We are all aware of the beetle epidemic on the Western Slope. Anyone
who has driven I-70 westward has seen it.
In our own area, we need to be aware of the condition of our trees.
Over-crowded, stressed, or damaged trees are vulnerable.

Living pines should not be trimmed or cut between approximately
beginning of June to approximately September, as beetles are attracted
to the scent of sap.
Wood (and probably anything else) should not be stacked against living
trees.
Beetles don't acknowledge property lines. We must work together as
residents of Magnolia to protect our forest. Stay alert, communicate
with your neighbors. Know the signs of beetle presence. Know how to
determine whether beetle presence in a tree has been repulsed by the
tree, or is killing it. Not all attacked trees succumb! Healthy trees
can expel beetles in a flood of sap.

If you have concerns, call the Colorado State Forest Service
(303-823-5774), and/or a neighbor who has experience with beetle
management. Dan Metzger is one such person.

Here are some websites with info on Pine Beetles.
