Mountain Pine Beetle SituationVanderhoof Forest District Nathan Voth Stewardship Technician November 21, 2003
Topics of Discussion • Graph showing hectares of MPB damage • What does the graph tell us? • What does it look like from the air? • Where do we go from here?
What does the graph tell us? • ~ 60% of the mature pine in the THLB has already been attacked and killed by MPB • at least 85% of the mature pine in the THLB will have been attacked and killed within 2 years, unless we get two consecutive cold weather events • the main MPB infestation will have moved outside the Vanderhoof Forest District within 3 years
What does it look like from the air? • the following 6 photos were taken during a flight on September 30, 2003 • the only live trees remaining will be deciduous, spruce, pine less than about 40 years old and a small percentage of the mature pine
Where do we go from here? • continue the harvest of green attack to reduce the spread of MPB into neighboring districts • develop and implement a salvage strategy • identify and implement opportunities to minimize timber supply shortfalls and impacts on other resource values
