Plant and fungi phenology
- The timing of seasonal events in plants is changing across Europe, mainly due to changes in climate conditions. Seventy-eight per cent of leaf unfolding and flowering records show advancing trends in recent decades whereas only 3 % show a significant delay. Between 1971 and 2000, the average advance of spring and summer was between 2.5 and 4 days per decade.
- As a consequence of climate-induced changes in plant phenology, the pollen season starts on average 10 days earlier and is longer than it was 50 years ago.
- Trends in seasonal events are projected to advance further as climate warming proceeds.
