Answers 2024
advanced assessment {Level 3) - Correct Answer an assessment performed to provide
detailed information about specific tree parts, defects, targets, or site conditions.
Specialized equipment, data collection and analysis, and/or expertise are usually
required
canker - Correct Answer localized diseased area on stems, roots, and branches. Often
shrunken and discolored.
cavity - Correct Answer open or closed hollow within a tree stem, branch, or root,
usually associated with decay.
cellulose - Correct Answer complex carbohydrate found in the cellular walls of the
majority of plants, algae, and certain fungi.
client - Correct Answer the person or organization for whom professional services are
rendered. Usually, the owner or manager responsible for the trees.
clinometer - Correct Answer instrument used for measuring the height of a tree or other
structure.
,CODIT - Correct Answer acronym for Compartmentalization of Decay in Trees (see
compartmentalization).
codominant (trees in a stand) - Correct Answer more than one tree sharing dominance
in a stand of trees.
codominant stem - Correct Answer forked branches nearly the same size in diameter,
arising from a common junction and lacking a normal branch union.
column of decay - Correct Answer wood decay inside a tree that extends longitudinally
up and down a seem or through a branch.
compartmentalization - Correct Answer natural defense process in trees by which
chemical and physical boundaries are created that act to limit the spread of disease and
decay organisms (see CODIT).
compression - Correct Answer in mechanics, the action of forces to squeeze, crush, or
push together any material or substance (contrast with tension).
compression crack - Correct Answer fracture caused by compressive stress.
,compression wood - Correct Answer reaction wood in gymnosperms, and some
angiosperms, that develops on the underside of branches or leaning trunks and is
important in load bearing (contrast with tension wood}.
conclusions - Correct Answer the summary and results of a risk assessment.
conk - Correct Answer fruiting body or nonfruiting body (sterile conk) of a fungus. Often
associated with decay (see bracket).
consequences - Correct Answer outcome of an event.
consequences of failure - Correct Answer personal injury, property damage, or
disruption of activities due to the failure of a tree or tree part.
constant occupancy - Correct Answer a target is present at nearly all times, 24 hours a
day, 7 days a week.
corrected lean - Correct Answer tree lean characterized by a leaning lower trunk and a
top chat is more upright as a result of self-correction; sweep.
crack - Correct Answer separation in wood fibers; narrow breaks or fissures in stems or
branches. If severe, may result in tree or branch failure.
, decay - Correct Answer process of degradation by microorganism
acceptable risk - Correct Answer the degree or amount of risk that the owner, manager,
or controlling authority is willing to accept.
acceptable risk threshold - Correct Answer the highest level of risk that does not exceed
the owner/manager's tolerance.
adventitious branch - Correct Answer branch arising from a stem or parent branch and
having no connection to apical meristems.
adventitious root - Correct Answer roots arising from roots or stems and having no
connection to apical meristems.
aerial inspection - Correct Answer inspection of the upper tree parts not readily
accessed from the ground; typically done by climbing or from an aerial lift
aerial patrol - Correct Answer overflights of a utility right-of-way, large areas, or
individual trees in a defined area to record the location of trees that are likely to fail and
cause harm.
