If mulch has been used to protect a tree in a construction zone, what should happen to the mulch after the construction is over?
Leave all of the mulch there to provide organic material and prevent weeds.
Burn the mulch to clear it.
Thin the mulch to 2-4 inches deep.
Pile up the mulch around the base of the trunk
Thin the mulch to 2-4 inches deep.
Written _______________________ should detail exactly what can and cannot be done to and around the trees.

Specifications
When soils are compacted by construction equipment, trees usually decline because: Select only one answer.
all of these
root growth and expansion may be diminished
the ability of the roots to absorb water and minerals decreases
oxygen availability is reduced
All of these
If the soil grade on a construction site is _________________, a large percentage of a tree’s root system might be removed.
lowered
raised
Lowered
True or False
There is far more that an arborist can do to treat trees that have been damaged by construction than to prevent the damage.
False
True or False
The largest, most mature trees are not always the best candidates for preservation.
True
Which of the following are reasons that arborists should be involved early in the construction process? Mark all that apply.
There is often little arborists can do to treat construction damage that has already occurred.
Once construction has begun, it may be too late to save the trees.
Trees should be assessed for health and quality before construction.
The arborist may be able to talk the owner out of construction.
Tree protection measures should be written in the specifications.

If a significant portion of a tree’s root system has been removed during building construction, a step that will help preserve the tree is:
construction of a tree well
pruning one-third of the crown to compensate for root loss
None of these
a surface application of a high rate of soluble nitrogen
None of these
True or False
The overriding objective of an arborist involved in a development project is to save every tree on the site.
False
If the soil grade on a construction site is __________________, even temporarily, the tree’s roots might be suffocated due to lack of oxygen availability.

The _________________ is the area around the tree or groups of trees in which no grading, excavation, or construction activity is to occur.

True or False
It is better to tunnel directly under a tree than to cut directly across the root system of a tree when excavating for utility lines.
True
A technique used to reduce soil compaction around trees on a construction site is to spread a temporary, thick layer of _____________________.
