Aosaar, J., Varik, M., Lõhmus, K. and Uri, V. 2011. Stemwood Density in Young Grey Alder (Alnus incana (L.) Moench) and Hybrid Alder (Alnus hybrida A. Br.) Stands Growing on Abandoned Agricultural Land. Baltic Forestry 17(2): 256-261

The aim of the study was to determine the density of oven dry stemwood (moisture content 0%) of two fast-growing tree species, grey alder (Alnus incana (L.) Moench) and hybrid alder (Alnus hybrida A. Br.), growing on abandoned agricultural land. The study is based on two 16-year-old experimental stands located in Southern Estonia (N 58°3′ E 27°1′). The average stemwood density of grey and hybrid alder was 396±32 kg m^-3 (average ± st. error) and 427±29 kg m³, respectively.<
For grey alder, the impact of stem height section on stemwood density was significant in all cases (p<0.005); it was higher in the upper stem sections. A similar trend was revealed for hybrid alder.
There was no correlation between breast height diameter and average stemwood density either for grey alder or for hybrid alder.
