arborist wood chips: a mulch consisting of woody tissue from a tree, obtained during tree-trimming
operations.
ASCA: American Society of Consulting Arborists
basal flare: The rapid increase of diameter that occurs at the junction of the trunk and root crown, associated
with stem and root tissues.
cabling: Installation of hardware in a tree to help support weak branches or crotches
codominant stems: stems or branches of nearly equal diameter, often weakly attached
compartmentalization: physiological process that creates the chemical and physical boundaries that act to
limit the spread of disease and decay organisms (ANSI A300)
cracks: defects in trees that, if severe, may pose a risk of tree or branch failure
crown: the aboveground portions of a tree
crown cleaning: selective pruning to remove one or more of the following parts: dead, diseased, and/or
broken branches(ANSI A300)
DBH or DSH: diameter at breast or standard height; the diameter of the trunk measured 54 inches (4.5 feet)
above grade
DGL: diameter at ground level
end weight: accumulation of mass at the end of a branch
feeder roots: common term to describe fine, non-woody, short-lived roots than absorb water and mineral
nutrients

pathogen: causal agent of disease
phototropic growth: growth toward light source or stimulant
PNWISA: Pacific Northwest Chapter of International Society of Arboriculture (ISA)
quantitative tree risk assessment: a process to estimate numerical probability values for consequences and
to calculate numeric values for risk (ISA 2013)
root crown: the point at which the trunk and buttress roots meet
scaffold branches: the major structural support branches that attach to the trunk
seam: the characteristic vertical line that appears where two edges of woundwood or callus ridge meet.
Commonly found at branch junctions where bark is included and between the two edges of callus-
woundwood at the center of a cavity or wound
structural defects: flaws, decay, or other faults in the trunk, branches, or root collar of a tree, which may
lead to failure
target: person, object, or structure that could be injured or damaged in the event of tree or branch failure
tree protection zone: a space above and below ground within which trees are to be retained and protected
VTA(Visual Tree Assessment): method of evaluating structural defects and stability in trees by noting the
pattern of growth. Developed by Claus Mattheck.
windthrow: type of tree failure associated with uplifting of the entire root plate, often occurring in high wind.
