Mountain Pine Beetle
Pathogens and insects are always at work in the natural and in the urban forest causing challenges for the forest managers. Although there are other agents at work in the urban forest, the mountain pine beetle has been the City’s primary urban forest health concern for the past few years.
The City’s program to remove mountain pine beetle-infested trees in various parts of the city is nearly complete. Much of the work has been completed in the City’s parks and open spaces, however there are still areas to address. Dead pine trees in open forest areas contribute significantly to the elevated risk of wildfire from the buildup of forest fuels. Working to remove these is part of the Wildfire Hazard Mitigation Program. For more information about the City’s strategy for managing the interface fire hazard, click here.
City of Prince George staff and contractors used state of the art, low impact small-scale salvage techniques to carefully remove trees. As much as possible, forestry operations were conducted during the winter months to avoid bird nesting season and fire hazards in urban areas from piles of tree debris during tree removal. Snow and frozen ground provided some measure of protection from undue equipment damage to the soil and smaller plant communities. Most of the logs were processed in local sawmills, and all debris was removed from site. In most cases, the signs that forest harvesting operations once took place are being obscured by the abundant regrowth of vegetation in response to increased sunlight reaching the forest floor.
The most obvious pest of the native tree population has been the Mountain Pine Beetle. Other pests of native tree species are cyclical and generally best left to run their course.
