First leaf

Record first leaf when the leaf is fully open and recognisably the shape, if not the full size of the adult leaf.

If you have recorded beech events before, please continue to record on the same tree.

Expected date range: early April to mid May

Available historic data: we have individual records from 1753-1810, and from 1845-1887. We have good records from 1938-1947, and from 1980-1999.
