Module 3.) Target Assessment Flashcards
people, property, or activities that could be injured, damaged, or disrupted by a tree failure.
Target
the monetary worth of something; the importance or preciousness of something.
Target Value
the area where a tree or tree part is likely to land if it were to fail.
Target Zone
target that cannot be easily relocated.
Static Target
target that can be relocated.
Movable targets
a target that is in motion or intermittently moving.
Mobile Target
the amount of time targets are within a target zone.
Occupancy Rate
a target is present at nearly all times, 24 hours a day, 7 days a week.
Constant Occupancy
the target zone is occupied for a large portion of the day or week.
Frequent Occupancy
the target zone is not commonly used by people or other mobile/movable targets.
Rare Occupancy
structures, trees, branches, or other factors that would prevent or reduce harm to targets in the event of a tree failure.
Protection Factors
a delay or interruption of progress or continuity.
Disruption
personal injury, property damage, or disruption of activities due to the failure of a tree or tree part.
Consequences of Failure
the amount or extent of injury, damage, or disruption.
Degree of Harm
a process for classifying targets according to importance or value.
Stratifying targets
a process for ranking targets according to importance or value.
Prioritizing targets
a process for ranking targets according to importance or value.
Prioritizing targets
True/False
Mobile targets always have a frequent occupancy rate in the target zone.
False
True/False
Occupancy rates of targets might fluctuate with the seasons.
True
True/False
The target zone for a whole-tree failure on level ground is approximately equal to the height of the tree, but if the tree is dead and/or brittle, the target zone should be expanded to 1.5 times the tree height.
True
The likelihood of impact is __________ if the chance of the failed tree or tree part impacting the specified target is remote.
very low
The __________ is high if the failed tree or tree part is likely to impact the target.
likelihood of impact
The consequences of failure are __________ if there will be no personal injury, low value property damage, or disruptions that can be replaced or repaired.
negligible
Targets can be __________ or __________ based on importance or value, which can be useful for municipalities managing large tree populations.
stratified
prioritized
