Popov S.Yu. 2016. The vegetation of spruce forests in the Pinega State Reserve. Nature Conservation Research 1(2): 38–58. https://dx.doi.org/10.24189/ncr.2016.016

The Pinega Natural State Reserve is located in the Arkhangelsk Province in the northern taiga subzone. Spruce forests represent the dominant vegetation formation of its territory. The vegetation of this forest is classified, based on 192 phytosociological descriptions. It reveals 12 associations, which represent 7 groups of associations. Detailed characteristics of these syntaxa, including analysis of their biodiversity, are provided. The revealed syntaxa differ both in species composition and environmental conditions: moisture, nutrition, nitrogen availability and acidity. Most poor conditions in terms of mineral nutrition occupy sphagnous spruce forests and bilberry-dominated spruce forests, while under the richest conditions varioherbaceous, humidoherbaceous and nemoral-herbaceous spruce forests occur. The Pinega Reserve is the only locality, where the Piceetum rubo saxatilis-vacciniosum association occurs in the northern taiga subzone.
