EXAM 3 FORESTRY Flashcards
what is tolerance
the ability to withstand stress
why do trees in wetlands often develop root and stem adaptations
the knees are located above the water level with provides more oxygen to the tree
is black spruce always a bog species
black spruce is the most abundant in wet soils, especially bogs
do the bald-cypress, larch, and white cedar have good rot resistance
heartwood trees are very rot-resistant
what are the two land survey systems used in the US
metes and bonds
US public land survey
where should you prune a branch
make a shallow cut on the underside of the branch, 1-2 inches beyond the brach collar
how can tree diversity be quantified
5-10% species
10-20% genera
15-30% family
when selecting a tree how is cold tolerance used
average lowest temperature each year over 30 years
how is available tree rooting area (soil volume) and compatibility of the final planting site used to select urban trees
ensure required soil volume for a tree species to maintain tree growth and longevity
what are the effects of inadequate soil volume on tree growth and longevity
tree will not have the nutrients it needs
tree will not reach full growth potential and lifespan
what are some example benefits of the urban forest
shade
aesthetics
water interception
energy conservation
reduction in violence
reduce stress
real commerce
What are the four variables used to account for the compensatory value of a landscape tree
size, condition, location, species
is the UWSP urban forest providing more benefits than costs associated with managing this tree population
yes
where should the structural roots be planted
at least 2 structural roots should be planted within 1-3 inches from the soil surface, measured 3-4 inches from the tree trunk
Know the important parts of a forest health lifecycle to exploit
insect part:
elm bark beetle, sap feeding bettle, emerald ash borer
disease part:
fungus transmission
tree biology part:
how the tree gets infected
