Western Spruce Budworm

Western spruce budworm (Choristoneura occidentalis) is a primary defoliator of interior Douglas-fir in British Columbia (BC). During outbreak situations, defoliation can result in significant damage to infested trees which can in turn negatively affect various land values.

What is the City of Kamloops Doing?
Observations by City of Kamloops Natural Resource staff noted an apparent significant increase in Spruce Budworm occurrence in the summer of 2007 over previous years. The City of Kamloops contracted a forest health specialist to conduct egg mass surveys and developed a City-wide Spruce Budworm management plan in the fall of 2007.

Egg mass surveys indicated infestation levels to be moderate in Kenna Cartwright Park and low in all other City-owned areas in the City. The consultant recommended aerial spraying of 300 hectares within Kenna Cartwright Park with Btk for the spring of 2008. This program was completed on June 7, 2008.

City-wide egg- mass surveys conducted in the fall of 2008 will determine future management actions on City owned properties.
