Serbian spruce (Picea omorika (Pančić) Purkyné) - endemicity and advantages
, 2020 Conifers, as a response to mechanical stress, such as wind and stem lean, form reaction wood called compression wood (CW). CW occurs in a range of gradations from near normal wood (NW) to severe CW (SCW). As the severity of CW affects the mechanical and chemical properties of wood, and as CW has limited value in the forest products industry, it is ...

Tailoring conservation to suit Serbian spruce
, 2021 Mediterranean forest tree species are particularly sensitive to the global climate warming, and two Mediterranean conifers, Sicilian fir and Serbian spruce, stand out as currently the most threatened ones due to their extremely narrow distribution range. Both species are IUCN-red listed and protected by the law.
