SUMMARY OF CURRENT INFESTATION
Found 3 infested pixels in Walkthrough with one code 1 attacked tree in each.. These were in the Western portion of polygon within a
mostly Balsam patch with Larger DBH Spruce. While only 3 Code 1 trees found which are on a two year cycle, there was plenty of older
attacked spruce scattered throughout polygon with it more prevalent around wet area in the east and along the draw there.
LIGHT SCATTERED ATTACK
ACCESS
Truck parked on Giscome Road. Than sled on unplowed road for 12km to polygon. Road accesses north edge of polygon
POLYGON FEATURES
(Topography, Terrain, Timber Types, Age)
Road along top of polygon. Slope rising north to south 0-30% throughout polygon. Areas with heavy balsam with scattered patches of
spruce. All trees large DBH.
SIZE, BOUNDARY and PATTERN OF INFESTATION
Walkthrough found 3 code 1 trees on 1st of two year cycle. Scattered Code 5 attack throughout polygon. Light scattered attack on larger
spruce trees
INCIDENCE AND SEVERITY OF ATTACK
Light sanitation rating from two probe lines also light larval density. Patchy infestation with three infested pixels having one code 1 tree
in each.
RISK OF BEETLE SPREAD
With little attack noticed and minimal spruce, low rate of spread. Lots of older attack on east side of polygon and also scattered
throughout, may be isolated other attack not picked up through that area as well although none noticed.
ACCESS, OPERABILITY and INTEGRATED RESOURCE MANAGEMENT ISSUES
Good access with unplowed road along top of polygon, couple of drainages run through and wetter on east side.
RECOMMENDATIONS
OPTION 1
MONITOR
As only 3 code 1 trees found and scattered in a stand dominated by Balsam, best to shcedule another walkthrough 2016/2017.
There are many code 5 attacked trees and infested trees found are on the first year of a 2 year cycle.
OPTION 2
TRAP TREES
As close enough to a road (Unplowed), would be effective to Lay trap trees in Fall Winter 2016/2017 as infected trees are on the
first year of a 2 year cycle with flight in 2017. Can work into plans within area.
