Abstract Detail
Ecology Rice, Stanley [1]. A twelve-year phenological record of earlier budburst in Oklahoma deciduous trees. Phenological responses provide an indicator of global climate change that integrates many factors and is biologically relevant. Warmer winters and earlier spring budburst are indicated by comparisons of current budburst with historical budburst dates, and by satellite imagery of spring greening. I provide a twelve-year record (2006-2017) of budburst dates for over 350 individuals of 22 deciduous tree species in southern Oklahoma. Budburst occurred in many species three weeks earlier in 2017 than in 2006. Species with early budburst, such as sweetgum and post oak, showed a much greater phenological shift than did species with later budburst, such as pecan. In some species, budburst date may be determined more by cumulative chilling than by warm spring temperatures. This three-week phenological shift is much greater than that observed in other parts of North America. Log in to add this item to your schedule
