Couverture géographique

The Iremel mountain group is located in the region of the highest elevations of Southern Urals within the Iremel-Avalyak mountain region. On the joint base of the Iremel mountain range, two peaks rise – Bol’shoy and Malyy Iremel (1582 and 1450 m above sea level, respectively). The elevation range of 1100–1150 m above sea level is occupied by spruce and spruce-birch sparse forests of a park type as well as tall-herb meadows dominated by Koenigia alpina and Bistorta officinalis; a range of 1350–1400 m is mainly occupied by spruce and birch shrub forests with low-herb meadows. Elevations above 1400 m occupied by mountain tundra. The herb–moss tundras prevail, but there are also stony, lichen, dwarf shrub–moss, and complex tundra types. The main tree species forming the upper forest line are Picea obovata and Betula pendula spp. tortuosa. Sampling plots were placed at an altitude of 1200–1350 m above sea level within the present-day ecotone of the upper forest line. At the southern slope of Malyy Iremel and the north-eastern slope of Bol’shoy Iremel plots were located in two types of biotopes (birch-spruce sparse forest and spruce forest with fragments of meadow plant communities); at the south-western slope of Malyy Iremel in three types of biotopes (birch-spruce shrub forest, birch-spruce sparse forest and spruce forest with fragments of meadow plant communities).

Méthodes d'échantillonnage

The sampling process included direct naked eye observations of all vascular plant species in ground vegetation in sampling plots of two sizes (0.5×0.5 m and 10×10 m). Each plot was described according to the common practice of geobotanical description. A large number of plots (700 in total) make it possible to take into account the irregularity in distribution of plant species within the study sites. The use of small-sized sampling plots allows obtaining quantitative data (frequency of species occurrences) to estimate the species abundance.

Description des étapes de la méthode:

1. Vertical transects were established across the treeline ecotone at the south-western and southern slopes of Malyy Iremel and the north-eastern slope of Bol’shoy Iremel (three transects on each slope, nine transects in total). At the southern slope of Malyy Iremel and the north-eastern slope of Bol’shoy Iremel, two elevation levels were selected (the corresponding biotopes are birch-spruce sparse forest and spruce forest with fragments of meadow plant communities). At the south-western slope of Malyy Iremel, three elevation levels were selected (the corresponding biotopes are birch-spruce sparse forest, birch-spruce shrub forest, and spruce forest with fragments of meadow plant communities). Three sampling sites 20×20 m (also referred to as macro-plots (=locationID), 21 in total) were placed within each elevation level. The central points of the sampling sites were positioned at a distance of 50–70 m from each other. At each elevation level, within two sampling sites, 12 plots with a size of 1×1 m were located (total number 168), within which, in turn, four sampling plots with a size of 0.5×0.5 m were placed (total number 672; the first method for assessment of plant species composition). The third sampling site within each elevation level was divided into four sampling plots of 10×10 m (total number 28; the second estimation method). All observations of plant species composition were carried out during July 2003.
