Where should you prune a tree? - dEtailEd aNSwER-Before the branch collar
What is tree diversity? - dEtailEd aNSwER-Having a selection of different trees
How can diversity be quantified? - dEtailEd aNSwER-Species, genera, family
When selecting a tree, how is cold tolerance used? - dEtailEd aNSwER-Finding a tree that can
withstand the mean annual minimum temperature of the area it is to be planted
How is available tree rooting area and compatibility of the final planting site used to select urban
trees? - dEtailEd aNSwER-Trees that have an appropriate rooting size for the area it has to
grow in (if there is too large of a root system, it can cause damage)
What are two effects of inadequate soil volume on tree growth and longevity? - dEtailEd
aNSwER-1.
Trees are smaller
2. Trees live for a shorter amount of time
What are some example benefits of the urban forest? - dEtailEd aNSwER-Stress levels
reduced, shade, aesthetics, water inception, energy conservation, reduction in violence, retail
commerce, traditional forest products
, What four variables are used to account for the compensatory value of a landscape tree? -
dEtailEd aNSwER-Size, condition, location, species
Is the UWSP urban forest providing more benefits than costs associated with managing this tree
population? - dEtailEd aNSwER-Yes
Where should the structural roots be at planting? - dEtailEd aNSwER-Right below the surface
of the earth

How does the host get infected with OW? - dEtailEd aNSwER-Through an open wound
What is a symptom? - dEtailEd aNSwER-The plant expression to the problem
What is a sign? - dEtailEd aNSwER-The actual agent that causes the plant disorder
What is a symptom of DED? - dEtailEd aNSwER-Canopy leaf flagging
What is canopy leaf flagging? - dEtailEd aNSwER-Leaf yellowing to browning
What is a symptom(s) of OW? - dEtailEd aNSwER-Canopy leaf loss, outer leaf tanning
What are the primary transmission rates for DED? (insect and root graft) - dEtailEd aNSwER-
90% insect, 10% root graft
