[50], In June 2019, Defra published a report summarising the current state of knowledge of ash dieback, and priority areas for future research. [7] The origins of the disease are uncertain,[10] but researchers are investigating the theory that the fungus originated in Asia, where ash trees are immune to the disease. [51] In response to the findings on the new hosts, Nicola Spence, the UK Chief Plant Health Office, said that, "Landscapers, gardeners and tree practitioners should be vigilant for signs of ash dieback on these new host species, and report suspicious findings through Tree Alert". According to a report published in the Journal of Ecology a combination of the disease and emerald ash borer attacks could wipe out European ash trees. Trees now believed to have been infected with this pathogen were first reported dying in Poland in 1992. [31], There are currently no effective strategies for managing the disease, and most countries which have tried to control its spread have failed. [45][46], In December 2016, writing in Nature,[47] Dr Richard Buggs reported that the common ash (Fraxinus excelsior) had been genetically sequenced for the first time and UK specimens appeared more resistant than Danish ones.

[14] By 2008 the disease was also discovered in Scandinavia, the Czech Republic, Slovenia, Germany, Austria and Switzerland. [11] Research at the Swedish University of Agricultural Sciences suggests that the deliberate destruction of trees in an infected area can be counterproductive as it destroys the few resistant trees alongside the dying ones. [32], The fungus was first found in Britain during February 2012 at sites that had received saplings from nurseries in the previous five years. It is now widespread in Europe, with up to 85% mortality rates recorded in plantations and 69% in woodlands. p. 35-36 in: Garnier-Delcourt, M., G. Marson, Ch. [3][4] "hymenoscyphus fraxineus."

Hymenoscyphus fraxineus has been proposed to be native to East Asia (Zhao et al., 2013). [2] It is closely related to a native fungus Hymenoscyphus albidus, which is harmless to European ash trees. On 9 November 2012 the United Kingdom Government unveiled its strategy. Related topics. Gross at al. [9] The sexual, reproductive stage, (teleomorph) grows during summer on ash petioles in the previous year's fallen leaves. [2] The disease has caused a large-scale decline of ash trees across Poland,[20] and the experience there suggests that in the long term "15 to 20 per cent of trees do not die, and show no symptoms. [6] In 2009, based on morphological and DNA sequence comparisons, Chalara fraxinea was suggested to be the asexual stage (anamorph) of the ascomycete fungus Hymenoscyphus albidus.
