NRES 250 EXAM 3 QUESTIONS AND
ANSWERS 100% PASS
Where should prune a tree branch - ANS From the top of the branch bark ridge to the branch
collar This minimize would size. Avoid flush cut, avoid tears/undercut/trunk damage.
what is tree diversity and how can diversity be qualified - ANS Tree Diversity: Multiple
different species of trees in one area. Increases odds of resiliency to a point
1. <= 5 to 10% species
2.<= 10 to 20% genera
3. <= 15 to 30% Family
When selecting a tree how is cold tolerance used - ANS Plant hardiness based on mean
annual minimum temperature that a plant can survive in (average lowest temperature each
year over 30 years)
What are two effects of inadequate soil volume and tree growth and longevity - ANS Smaller
width and height of trees
what are some example benefits of the urban forest - ANS Shade, Aesthetics, Water
interception, Energy conservation, Reduction in violence, Reduced stress, Retail commerce and
Forest products

Is the UWSP urban first providing more benefits than costs associated with managing thus tree
population - ANS More benefits
Where should the structural roots be at planting - ANS With in 1 to 3 inches of soil surface
(measured 3-4 inches from the trunk)
Know important parts of a first health lifecycle to exploit
a. Insect part
b. Disease part
c. Tree biology part - ANS 1.
- Beetles lay eggs under bark of logs
- Beetle galleries then created under the bark
- Beetles go in tunnel with fungus
- Then emerge out carrying the fungus scorers and fry to health trees
2.
- Grows on outside of bark spores
entrys:
Elm bark beetles (90%)
-grafted roots (10%)
3. Beetles emerges with fungus and feels to next host and feed on twigs and despots spores
What is a symptom and sign - ANS Symptom: is the plant expression to the problem
Sign: Is the actual agent (insect, fungus, the thing that causes the plant disorder)

and 10% root graft
OW: 10% insect and 90% root graft
EAB: 100% insect and 0%root graft
Know what sanitation is and how sanitation reduces tree mortality - ANS Sanitation: Removal
of trees that have been injured/killed.
Reduces tree mortality: To prevent spread of seas or insects (cost a lot of money)
