ISA Certified Arborist Exam () Test Questions
and Verified Rationalized Answers, 100% Passing Score
1. In which direction should a chain saw operator move if
he or she loses control of the tree while felling?
a. 45 degrees to either side of a line opposite to the intended
direction of fall
b. In a line opposite to the intended direction of fall
c. In a line perpendicular to the intended direction of fall
d. Along the intended direction of the fall: A: If a chain saw
,operator loses control of the tree while felling, he or she should move
along a line 45-degrees to either side of a line opposite to the intended
direction of the fall. Moreover, there should not be any other people in
the area immediately behind the tree. Many arborists keep felling
wedges on hand while the back cut is being made. If necessary, these
wedges can be useful for keeping the tree from pinching the bar of the
chain saw. Arborists can also use felling wages to begin and control the
fall.
2. On which side of a tree should workers stand while limbing
or bucking?
a. The right side of the tree
,b. The left side of the tree
c. Uphill from the tree
d. Downhill from the tree: C: Workers should stand uphill from the
tree while limbing or bucking. This is to prevent the tree from rolling
over on the worker. In some cases, the arborist will need to use a wedge
or a block to keep the tree from moving. When multiple workers are
limbing or bucking the same tree at the same time, they need to be in
constant communication, and should have a pre-established system for
approaching or alerting one another. Limbing is the process of cutting
the side branches off a tree that has been felled. Bucking is the process
of cutting a tree trunk or log into shorter sections that are easier to
, manipulate.
3. Groups of different plants that need roughly the same
amount of water are called
a. hydrozones
b. aquasets.
