The spruce budworm outbreak in Maine during the 1970's has caused considerable

tree decline and scattered mortality to the spruce-fir forest. The

majority of mortality is occurring in areas where spraying is restricted because

of buffers around human habitation, buffers near water, mixed wood

stands with a low fir content, mountainous terrain and areas of fir insufficient

in size to be economically treated. A uniform survey method is desirable

to evaluate volume losses and assess growth reduction in these areas.

The survey of the Moosehorn Wildlife Refuge (M. E. Devine et. a1.) was an

attempt to gather data to answer questions concerning mortality and growth

rates on an untreated softwood stand. This was our first experience with

this type of survey, and parts of the method used assessing the Moosehorn

will be incorporated in formulating a uniform procedure of evaluating spruce

budworm damage.

Goals and objectives t,o be set for budworm assessment will change. from

survey area to survey area, but the method and data to collect will be constant.
