Please answer the following questions in your own words from the reading:  DO NOT USE OUTSIDE SOURCES.. THIS IS ANSWERING FROM THE ATTACHED. 

Explain the predictable and cyclical nature of Douglas-fir tussock moth (DFTM) activity. Why are there such boom-and-bust periods associated with the populations?

Monitoring and sampling for pest density is part of an integrated pest management (IPM) approach. Why is this an especially important step prior to employing any treatment for Douglas-fir tussock moth (DFTM)? Hint: would a forest manager want/need to treat for DFTM every year?

DFTM is a natural disturbance agent in a forest ecosystem. Consider how forest ecosystems respond to disturbance, and discuss what change (in vegetation, insects, soil) could come about in a forest habitat following a DFTM outbreak. Hint: regeneration.
