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:
- 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.
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.
