BCMA PRACTICE TEST 2
"When trees that have had steel cables installed many years previously are
examined it is not unusual to find
a. the tree has overgrown the anchors thus causing
an alarming loss in the strength and efficiency of
the support system.
b. the tree has overgrown the anchors thus killing
the cambium and limiting further secondary
growth.
c. the cable is now well below halfway from the
union to the top thus rendering it less effective
and perhaps inviting the risk of breakage of the
branch above the union.".
d. the cable is now higher than halfway from the
union to the top, decreasing the design advantage
and allowing too much movement at the union." - ANSWER "c. the cable is
now lower than halfway from the
union to the top, making it less effective and
possibly leading to breakage above the branch site."
"A small population of trees has been in decline due to a
clearwing moth issue of some sort.
You choose to put up pheromone traps to monitor the
pest because you know that
a. the pest population must reach a certain threshold
,for treatments to be effective.
b. only the female moth causes damage to the
foliage.
c. clearwing moths must be controlled at a specific
life stage.
d. you need to detect the moth's key predatory wasp." - ANSWER "c.
clearwing moths must be controlled at a specific
life stage."
"Golf course greens often utilize a sand-based root
zone layer placed over a gravel layer, which is above
a drainage system in the subgrade. This design
provides maximum removal of water during heavy
precipitation events, and it stores water above the
gravel during periods when the ground is not saturated.
The principle is known as a
a. gravitational drainage system.
b. capillary percolation design.
c. perched water table.
d. French drain." - ANSWER c. perched water table.
"As the owner/manager of a tree care operation, you
are required to provide training in all safe work practices,
use of personal protective equipment, and
a. interpersonal communication techniques.
b. emergency response procedures.
, c. professional job-site behavior.
d. quality assurance procedures." - ANSWER b. emergency response
procedures.
"A landscaper has been trying to control an infestation
of phloem-feeding insect pests by releasing
lady beetles and lacewings to augment the natural
populations—but is having limited success. You
Explain that a common problem with this
approach is
a. the kill of the pest population is quick but
lasts only a very short period.
b. pest resurgence typically occurs within a couple
of weeks.
c. secondary pest populations flare when the
target pest has been eliminated.
d. it takes time to build the population of
predators large enough to reduce the pests." - ANSWER "d. it takes time to
build the population of
predators large enough to reduce the pests."
"When a tree is dug for transplanting and the root
system is cut back severely, which hormonal effect
is most likely to occur?
a. The level of cytokinin production will be
increased and will trigger rapid shoot
