Info: The cambium is a thin layer under the bark. It is the only part of the trunk that grows outward to make the tree wider.
Tech Note: "Shall" means you must do it. "Should" is just a good idea. Knowing this difference is vital for safety tests.

Test 05 Study Summary

1. Chainsaw Safety The top of the bar tip is the danger zone. If it hits a log, the saw will kick back toward your face.
2. Soil Drainage Do not put gravel in the bottom of a planting hole. It stops water from draining and can drown the roots.
3. Rigging Math Always divide the breaking strength by the safety factor. A 10,000-pound rope with a 5:1 factor has a 2,000-pound limit.
