First leaf

Record field maple first leaf when the leaf is fully open and recognisably the shape, if not the full size of the adult leaf. The flowers appear with the leaves, from the same bud.

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

Expected date range: late March to early May

Available historic data: we have individual records for these years; 1770-1810, 1819-1865, and 1893-1947
