The purpose of this study is to decide whether outbreaks of the spruce budworm would have developed in the susceptible forests of New Brunswick in response to the relaxation of climatic control regardless of whether centers of heavy populations had existed in areas to the west. In Part 1 of this consideration was given to the role of climate in the initiation of outbreaks of the spruce budworm in New Brunswick.
