Abstract

•A phenology model for Douglas-fir was parameterized using 4500 flowering observations.•The phenology model predicted the day of flowering within an average of five days of observations.•Both chilling and forcing temperatures are important determinants of flowering time.•Trees from dry regions require less forcing prior to flowering than trees from wet regions.
