Presence of C. fraxinea confirmed by field studies (Skovsgaard et al., 2010).

According to the NPPO (2013): around 2003, ash dieback was sporadically seen in Danish forests. Then it spread to all parts of the country, affecting large parts of tree stands and often leading to tree death within few years from the symptoms' first appearance.
