Module 4 Flashcards
1
Q
Site assessments to consider
A
Previous tree failure Terrain Wind pattern Soil characteristic Drainage patterns Land disturbances (flooding, grade changes, hydrology) Construction damage Restricted root growth Land use history Tree health
2
Q
Wind loads
A
The force on a tree or structure resulting from the impact of wind
Use typical weather conditions for the region
3
Q
Windthrow
A
Susceptible to windthrow when the soil is saturated, particularly if they are shallow rooted, soil not deep and high water table
4
Q
Dominant trees
A
Typically open grown and free from competition.
5
Q
Subdominant
A
Understory trees that have less developed crowns and weaker root systems
6
Q
Suppressed trees
A
Biologically and mechanically weak. Restricted by competing trees.
7
Q
Likelihood of failure is determined by
A
Site factors Response growth Tree health Tree species Load Defects and conditions
8
Q
During site assessment consider
A
Drainage patterns Land use change Restricted root growth New exposure History of failures Saturated soil Common weather
