Ash dieback, caused by the ascomycete Hymenoscyphus fraxineus, was first observed in the eastern and southernmost Norway in 2008. Based on the age of stem bark lesions, it was concluded that the fungus had arrived to the region no later than 2006. Since 2008 the annual spread of the disease northwards along the west coast of Norway has been monitored. The registration was done each year during early summer around a disease frontier recorded in the previous year. The occurrence of necrotic bark lesions in the previous-year shoots and dieback of these shoots, and isolation of H. fraxineus from the discoloured wood associated with necrotic bark lesions were used as signs of ash dieback. These records indicate an annual spread of ash dieback in the range between 25 km and 78 km, and a mean annual spread of 51 km. The cause of the spread is discussed.

Askeskuddsjuke har spredd seg med rekordfart i Europa og i Norge. Ask (Fraxinus excelsior) er meget sensitiv for denne nye sjukdommen. De aller fleste områder i Europa med dette treslaget er nå infisert med sekksporesoppen askeskuddbeger (Hymenoscyphus fraxineus) som forårsaker sjukdommen. I Norge ble askeskuddsjuke første gang registrert i 2008 og allerede da ble den funnet over store deler av Østlandet og Sørlandet. Deretter har askeskuddsjuke spredd seg nordover på Vestlandet i gjennomsnitt 51 km per år. I 2016 ble det nordligste funnet registrert i Aure kommune nær grensa til Trøndelag.

Forest covers 37% of Norway’s combined area, almost half of which is made up by the tree species called Norway spruce. The rest consists of mostly pine and birch. It is therefore only natural that spruce forests should feature so heavily on black metal album covers and lyrics. The extreme music genre of black metal, as we think of it today, was birthed in Norway. Although it could be said that its place of origin was accidental, the subsequent use and appropriation of that place’s topographic features was not. Since its inception in the early nineties, the genre has spawned countless bands across the globe, many who take on its misanthropic ethos, but also a deep reverence and respect for nature. Within black metal’s aesthetic, photographs of ominous black tree lines and lyrics about disappearing into the depths of the forest abound – it is almost as if the spruce tree has become its own character in the mythology that black metal has become.
