Spring phenology of balsam fir in Maine was investigated during 1978. Multiple regression models based on climatic and geographic factors were developed for predicting fir phenology and accounted for a maximum of 52.6% of the observed phenological variation. Generalized maps depicting observed and expected phenology patterns are also presented.
