Trubina M, Nesterkov A (2022). Diversity and distribution of vascular plants within the treeline ecotone in Mount Iremel (Southern Urals, Russia). Version 1.9. Institute of Plant and Animal Ecology (IPAE). Sampling event dataset https://doi.org/10.15468/6hsht5 accessed via GBIF.org on 2023-09-28.

Description

The dataset presents the results of an assessment of the species richness and frequency of vascular plants at the different elevation levels (from 1203 to 1348 m above sea level) and in the different biotopes (birch-spruce sparse forest, birch-spruce shrub forest, and spruce forest with fragments of meadow plant communities) in the Iremel mountain group (Southern Urals). Observations were carried out at 700 sampling plots using two estimation methods: small-size plot (0.5×0.5 m) sampling (672 plots in total) and large-size plot (10×10 m) sampling (28 plots). The dataset includes 700 sampling events (=sampling plots) corresponding to 5585 occurrences (vascular plants, identified mostly to species) and observed during July 2003. Only occurrences contained plant taxa (occurrenceStatus=present) have been provided. The dataset provides valuable information for estimating the biodiversity and composition of plant communities within the treeline ecotone, including the information about distribution and frequency of the Ural endemic species (Anemonastrum biarmiense (Juz.) Holub, Calamagrostis uralensis Litv., Cerastium krylovii Schischk. Et Gorczak., Festuca igoschiniae Tzvel., Hieracium iremelense (Elfstr.) Üksip, Lagotis uralensis Schischk, Pleurospermum uralense Hoffm.) and the Pleistocene relict species (Alopecurus glaucus Less., Bistorta vivipara (L.) Delarbre, Cerastium pauciflorum Stev. ex. Ser., Pedicularis oederi Vahl , Saussurea controversa DC., Swertia obtusa Ledeb.).

Sampling Description

Study Extent

The study was carried out in the Southern Urals, Russia, within the Iremel mountain group, at the different slopes of Bol’shoy (54° 31.2’ N, 58° 50.5’ E) and Malyy (54° 33.1’ N, 58° 53.5’ E) Iremel. A total of 700 sampling plots (672 plots of 0.5×0.5 m and 28 plots of 10×10 m) were established in three types of biotopes: 300 plots in a birch-spruce sparse forest, 300 plots in a spruce forest with fragments of meadow plant communities, and 100 plots in a birch-spruce shrub forest.

Sampling

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.

Quality Control

Identification of plant species was carried out mostly in the field; specimens with controversial species affiliation were herborized and identified later in a laboratory. Identification was cross-checked by specialists of the Institute Botanical Garden of the Ural Branch of the Russian Academy of Sciences (IBG UB RAS). About 90% of all occurrences of vascular plants have been identified to species.

Method steps

  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.

Geographic Coverages

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).
