The increased size, intensity and frequency of spruce budworm epidemics in Maine has demonstrated the need for intensified monitoring of the situation and the need for a uniform system of damage evaluation by the several interest groups gathering such data, For example, tree condition data taken by the entomologist primarily interested in budworm population counts should be compatible with tree condition data taken by the forester who is primarily interested in growth loss and mortality.
