BCMA - Practice Test 1 Exam Questions and
Answers (Solved Papers)
"Several small, ornamental trees in an irrigated
planting with full sun and significant wind exposure
are beginning to wilt and are exhibiting minimal
twig extension growth. The planting bed had
been mulched, but little mulch remains. What
diagnostic step would you take first?
a. Collect soil samples to send to the lab to test
for high pH and aluminum toxicity.
b. Probe the soil to check for moisture level and
penetration resistance, and look for signs of
water runoff.
c. Collect leaf samples to test for high levels of
herbicides that mimic drought symptoms.
d. Take an increment core to determine whether
the problem is chronic or acute." - CORRECT ANSWERS "Probe the soil to check for
moisture level and
penetration resistance, and look for signs of
water runoff."
"Prolonged flooding can be very damaging to trees
because the anaerobic conditions
a. increase the relative percentage of clay in the
,soil texture.
b. change the biological and chemical composition
in the soil.
c. cause the roots to grow deeper to escape the
surface water.
d. cause excessive percolation in the soil, destroying
micropores." - CORRECT ANSWERS "change the biological and chemical composition
in the soil."
"You are writing the specifications for tree preservation
on a development site. For the tree protection
zone barriers, you specify
a. 3 ft (1 m) high, metal rebar with hi-vis yellow
caution tape and ""Do Not Cross"" lettering.
b. 4 to 6 ft (1.2 to 1.8 m) high, sturdy metal fencing
that is anchored to the ground.
c. 3 ft (1 m) high, safety orange, plastic fencing
for visibility and ease of moving.
d. 6 ft (1.8 m) high, standard wooden privacy
fencing that is not set into the ground." - CORRECT ANSWERS "4 to 6 ft (1.2 to 1.8 m)
high, sturdy metal fencing
that is anchored to the ground."
"You are a consultant to a municipality looking to
contract line-clearance pruning. Previously, they
had contracted with a local tree service to top the
,trees below the wires. Instead, you recommend
directional pruning and explain the process of
a. removing or reducing interfering branches back
to lateral branches that are not growing in the
direction of the clearance zone.
b. removing or reducing all branches that grow in
the direction of the clearance zone to a predetermined
clearance distance.
c. directing growth away from the clearance zone
using only collar cuts back to the parent branches.
d. subordinating all lateral branches that are growing
toward the clearance zone and are greater than
one-third the diameter of the parent branches." - CORRECT ANSWERS "removing or
reducing interfering branches back
to lateral branches that are not growing in the
direction of the clearance zone."
"The best procedure for sending foliage samples to
a plant diagnostic lab for disease diagnosis is to
a. collect only affected leaves from the most affected
part of the canopy and send in a tightly sealed
paper bag.
b. collect a variety of affected leaves from throughout
the canopy and send in a sealed paper bag.
c. place both healthy and diseased leaves in separate,
sealed plastic bags.
, d. place both healthy and diseased leaves in a sealed
plastic bag wrapped in a wet paper towel." - CORRECT ANSWERS "place both healthy and
diseased leaves in separate,
sealed plastic bags."
"While easy to measure and simple to calculate,
cross-sectional strength formulas and threshold
values have some significant limitations such as
a. they overemphasize the amount of load on the
outer shell of wood.
b. a larger amount of wood is typically needed on
large trees than the formulas indicate.
c. the formulas assume that all cavities are open to
the outside of the tree.
d. they assume round stems with centrally located
cavities/decay." - CORRECT ANSWERS "they assume round stems with centrally located
cavities/decay.
"
"In the tree appraisal process, after the assignment
has been established, the scope of work defined,
and the data collected, the next step is to
a. calculate the appraised value using the trunk
formula technique.
b. analyze the data and apply the relevant valuation
approach(es).
