Picea omorika

Picea omorika is a tall conifer species that today only occurs in a small area at the border between Serbia and Bosnia Herzegowina, yet was widely distributed throughout Europe prior to the last glacial period. It is shade tolerant and has columnar, slender and dense crowns, reaching diameters of >100 cm. The wood is very similar to that of Picea abies, and can be used for construction as well as for pulp production. It is also often used as an ornamental in cities, because of its high tolerance to air pollution.
The locally endemic Serbian spruce naturally occupies a minute range in the Balkans, yet has been planted as ornamental tree in gardens since decades. While only very few species of herbivores have so far reported, it is very likely that most (if not all) spruce herbivores would accept that resource if more widely available.
