Light pollution is associated with earlier tree budburst across the United Kingdom

Ffrench-Constant et al. 2016

Scientists at the University of Exeter used Nature’s Calendar records to examine the relationship between artificial night-time light and the date of budburst in sycamore, beech, oak and ash. They found that earlier budburst in these species is associated with night-time lighting, and not just urban temperature effects. The late-budding species (oak and ash) were affected the most, with budburst occurring up to 7.5 days earlier in the brightest areas.
