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.
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.

d. xeriscapes.
A: Groups of different plants that need roughly the same amount of 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.
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
D: The goal of integrated pest management is to maintain a tolerable level of pest damage.
Integrated pest management 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 prioritize limiting collateral damage to the non-target
organisms (most notably, people).
Which of the following cuts is used in topping?
a. Thinning cut
b. Reduction cut
C. Heading cut
d. Pruning cut
C: Heading cuts are used in topping. Topping is an almost universally scorned form of pruning in
which the top of the tree is lopped off to a certain height. Besides being aesthetically unpleasant,
topping has a number of negative consequences for trees. First, topping drastically reduces the
volume of the leaf crown, which makes it extremely difficult for the tree to produce enough food.
Topping also makes the tree more susceptible to sun damage, disease, and insect infestation. Finally,
topping encourages the growth of numerous weak sprouts from the top of the tree. These water
sprouts, as they are known, can put a significant burden on the tree's already-taxed nutritional
resources.
Which of the following is NOT a common part of a biological control strategy for pests?
A+ TEST BANK 2
, Louisiana Arborist Exam
a. Poison
b. Parasites
c. Predators
d. Pathogens
A: Poison is not a common part of a biological control strategy for pests. In a biological control
strategy, the arborist enlists the support of a pest's natural enemies, whether they are predators,
parasites, or pathogens. The strategy will take one of three forms: introduction, conservation, or
augmentation. That is, the controlling agent may be introduced to the environment so that it can
reduce the population of the pest; the existing population of controlling agents may be supported;
or the existing population of controlling agents may be supplemented with organisms from the lab
or other natural environments. There is an obvious appeal to the idea of using natural means to
handle pests, but biological control strategies often are slow and require a great deal of oversight.
Moreover, it can be difficult to undo the effects of a biological control strategy.
What is the name for a large, irregularly shaped area of dead tissue on a leaf?
a. Dieback
b. Leaf blotch
C. Scorch
d. Gummosis
B: A leaf blotch is a large, irregularly shaped area of dead tissue on a leaf. Blotches are typically
caused by dryness, frost, fungus, chemical spray, sunscald, or insects. Dieback is the gradual death of
leaves and twigs, progressing from the tip back towards the base. It is generally the result of specific
nutrient imbalances, air pollution, vascular disease, or root damage. Scorch occurs when leaves turn
brown and black and when areas around the leaf edges and margins die. Gummosis is oozing gum or
sap from wounds or other openings in the bark.
What is the name of the technique used to keep nuts from backing off in a tree-bracing operation?
a. Propping
b. Peening
C. Guying
d. Dead-ending
B: Peening is the technique used to keep nuts from backing off in a tree bracing operation. Peening is
essentially just hammering the bolt ends so that they expand around the nuts. Propping is a
technique for supporting a weak or damaged limb. Guying is another support technique. It is the
installation of a cable between a tree and an external object.
Which of the following is not a standard part of the fertilizer analysis printed on the container?
A+ TEST BANK 3
, Louisiana Arborist Exam
a. Potassium phosphate
b. Soluble potash
c. Phosphoric acid
d. Total nitrogen
A: Potassium phosphate is not a standard part of the fertilizer analysis printed on the container. The
standard fertilizer analysis includes a breakdown of the total nitrogen, available phosphoric acid, and
soluble potash. These quantities are given as a percentage by weight: for instance, a 50-pound bag of
fertilizer listed as 8-5-4 will contain 8 percent nitrogen (4 pounds), 5 percent phosphorus (2.5
pounds), and 4 percent potassium (2 pounds). Complete fertilizers are useful in some cases, but
most trees only require nitrogen fertilizer.
With respect to the pull of the cable, in which direction should hardware be installed?
a. It does not matter.
b. Diagonally
c. Perpendicularly
d. Along the same line
D: Hardware should be installed along the same line as the pull of the cable. This arrangement
maximizes the strength of the hardware. If the cable pulls on the line at an angle, the forces exerted
on the hardware will be asymmetrical, and therefore the hardware will not be able to function at its
optimal strength.
When should plants that bloom on the wood from the previous season be pruned?
a. After the blooms are shed
b. After the first frost of the autumn
c. Just after they bloom
d. Winter
C: Plants that bloom on the wood from the previous season should be pruned just after they bloom,
ensuring that blooming buds are not removed from the plant. Although timing is important in the
promotion or discouraging of flowers or fruit, it is less significant in the removal of dead, diseased, or
broken branches, which can be removed at any time of year.
During construction, how far should the tree protection zone extend from the trunk of a young
tree?
a. 1 foot for each inch of trunk diameter
b. Two times the trunk diameter
