Abstract Ash dieback caused by Hymenoscyphus fraxineus was first recorded in Northern Ireland (NI) in November 2012. The disease was observed only on recently (<6 years) planted trees. An in‐depth case study in 2015 of an ash plantation with severe symptoms indicated that many of the trees were infected at the time of planting.
