Budburst
As the winter buds swell, they develop a white tip. Record beech budburst when the colour of the new green leaves is just visible between the scales of the swollen bud. Leaves and flowers come from the same bud.
If you have recorded beech events before, continue to record on the same tree.
Expected date range: mid March to early May
Available historic data: we have some records from 1987-1999
