Spruce weevil hazard rating project homepage of Brian Sieben
-
Brian Sieben explores several of the challenges in using thermal heat sums for hazard rating areas for potential damage by Pissodes strobi. In addition, he explores a warming scenario for the MacKenzie Basin and its impact on increased hazard for spruce stands in the area.

In this BC Forest Practices Code Guidebook (2001), a stand level survey is described that is intended to provide quantitative information on the
amount of damage caused by disease, insects, mammals (=wildlife) or abiotic
conditions (sometimes referred to as the DIMA incidence survey).
