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. Alongtheintendeddirectionofthefall
Ans- 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 canalso 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
Ans- C
Ans- Workers should stand uphill from the tree while limbingor 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, theyneed 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.
, C. drought zones.
d. xeriscapes.
Ans- A
Groups of different plants that need roughly the same amountof water are called
hydrozones. Arborists often arrange trees in hydrozones so that watering is
easier and less confusing. In addition, when there are variations in elevation at a
particular site, the arborist may place trees that need more water
at the higher elevations, so that the trees downhill can subsist entirely on the runoff
from the water applied to the higher trees.
4. What is the goal of integrated pest management?
a. To introduce species that prey on pests
b. To promote insect populations
C. To eradicate pests
d. To maintain a tolerable level of pest damage
Ans- D
The goal of integrated pest management is to maintain a tolerable level of pest
damage. Integrated pest man-agement was originally devised as an alternative to a
reliance on pesticides. It recommends a holistic approach to pest control, which
may include limited use
of pesticides. More importantly, however, integrated pest management strategies
create as little of a disturbance to the preexisting environment as possible and
