1."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.": "Probe the soil to check for moisture lev
and penetration resistance, and look for signs of
water runoff."
2."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.": "change the biological and chemical
composition in the soil."
3."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.

4."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.": "removing or reducing
interfer- ing branches back
to lateral branches that are not growing in
the direction of the clearance zone."
5."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.": "place both healthy and
diseased leaves in separate,
sealed plastic bags."
6."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.
