Review all species lists, especially 7 - 8. Remember the ID exam will cover all species lists.
Primary lecture topics have been:
· plant succession and stand development
· old growth forest issues
·
vegetation zones of
· tree response to climate change
· trees in the urban environment
Review these topics and the handouts and web lecture notes, with emphasis on the following questions:
What is a disturbance? What is the difference between primary and
secondary succession? How do
environments differ between early and late succession? Review the stages of stand development. How is succession different in western
How is old growth defined? What structural components are found there? What is a snag? Why do some animals only make their homes there? What is the food chain that links the northern spotted owl with old growth forests? What are pros and cons for banning logging in old growth?
How are vegetation zones named? What physical (environmental) features differ from zone to zone? What are the dominant tree species found in each of these zones? In which zones are you most likely to find the trees from our list that are native to Washington?
How have we learned about past climate change? How has it affected trees and forests? What can we learn about past climate change that helps us prepare for future climate change? What are the three major take-home lessons and how did we learn them?
Why are trees valued in urban environments? How are they problematic? What should we look for in choosing trees urban trees? What species work best? In which places? What are some pruning considerations for urban trees? Aesthetic considerations?
