Figure 2-A. Multipest Tally Sheet (FH 100, Prince George Forest Region).
Note: If multiple pests are found on a tree, record all pests on the same line (e.g., if both comandra blister rust and western gall rust are found attacking the stem, record both).
Note: If one pest is secondary (e.g., squirrel feeding damage on comandra cankers) record both but use a check mark in the squirrel column instead of per cent girdled.
Tips to remember:
The Prince Rupert Forest Region Multiple Pest Survey described in the Forest Health Surveys Guidebook can also be used to survey 10- to 35-year-old stands for pest (rust) incidence and damage.
- Galls are woody swellings, whereas blister rusts cause bark swellings.
- Squirrels usually only feed on pine stems >6 cm dbh. However, rust-infected bark on any size stem or branch is squirrel ice cream.
- Squirrels never feed on atropellis cankers.
- Giant conifer aphids can produce roughened bark; blister rust infections are usually accompanied by swollen bark (but not always).
- Comandra blister rust infections are usually within a metre or two of the ground. Watch for cankers at the ground line.
