“…The felling of junipers is a mechanism which triggers degradation of the ecosystem along with its endemic species. Archa forests play a protective role within their own and adjacent ecosystems (Rahmonov et al 2011a(Rahmonov et al , b, 2013Sadikov 2012).…”

“…In spite of widespread degradation, to date there has been no assessment and analysis of human impact on juniper forest transformation. The environmental consequences of human impact on the degradation of plant cover including rare and endemic species, as well as issues regarding nature protection, geobotanics, and soil science in the Fann Mountains, which are part of the Pamir-Alay system, have been presented in several papers: Rahmonov et al (2011aRahmonov et al ( , b, 2013Rahmonov et al ( , 2014, Sadikov (2012), and Rahmonov et al (2016). So far, these papers are the only available botanic references regarding the region under discussion.…”

Detailed analyses were conducted of human impact on juniper forest landscapes occurring within the Zarafshan Range (Pamir-Alay). Juniperus seravschanica and J. semiglobosa belong to forest-forming species in Central Asia. At present, juniper forests all over Tajikistan are seriously threatened as a result of excessive logging and cattle grazing. The aim of this paper is to present juniper forest transformation as a result of human activities as well as the diversity of soil properties in the organic and humus horizons in the altitudinal system of soil zonation. Three groups of phytocoenoses were distinguished: those with a dominant share of Juniperus seravschanica; those with a dominant share of J. semiglobosa; and mixed. Associations with Juniperus seravschanica and J. semiglobosa feature several variants of phytocoenoses with dominant species: Artemisia lehmanniana, A. dracunculus, Eremurus olgae,

Vegetation landscapes of fann Mountains are very diverse because of high-mountain character of this area, local climatic conditions, topography and habitats. That differentiation leads up to biodiversity and formation of unique plant landscapes and endemic species. The vegetation landscapes in altitude order are represented by forbs meadow steppe, thymes, swamp, broad-leaf forest, juniper forests, flood-plain small-leaved forest, tugai, light deciduous forest, pistachio, forbs wormwood, almond, rare vegetation with cushion-shaped species, wormwood eurotia, steppe, thorny grasses with shrub-steppe, rocks and taluses with rare vegetation alpine zones. high level of endemism in fann Mountains is connected to natural conditions such as geological structure, relief, high-mountain ranges and climate conditions.

“…However, over time hard coal mine spoil sites, despite their adverse conditions, are effectively colonized by plants and animals, which promote the development of vegetation. There are many studies on spontaneous succession on post-industrial sites from Central Europe (Cohn et al 2001;Rostan´ski and Woz´niak 2007;Frouz et al 2008;Rahmonov 2009;Chmura et al 2011;Rahmonov et al 2011;Kompała-Bąba and Bąba 2013;Chmura et al 2013), but still some of the processes occurring in these man-made environments are poorly understood especially in terms of their functional diversity Cabała et al 2004;Latzel et al 2011;Woz´niak et al 2011) and the ecosystem services they provide.…”

The history of coal mining in South Poland has left a legacy of many spoil heaps across the landscape. These have presented the opportunity to study their colonisation and spontaneous successional sequences over a long time period. We use the plant functional group (PFG) approach to characterize and compare species diversity on spoil heaps of different ages by utilising the ecological characteristics (PFG categories) of the species recorded during the course of spontaneous vegetation development. By changing species frequency into functional group frequency it was possible to find the significant differences in the functional composition of the studied vegetation and to analyze the dataset using non-parametric statistics. There was a small increase in the number of species over time, while the frequency of geophytes, nanophanerophytes and megaphanerophytes increased significantly. A significant increase was also recorded for the frequency of competitors, stress-tolerators and stress-tolerant competitors and for native species. We found that the significant differences in species composition measured as PFG diversity occurred between the youngest and the oldest age classes. The PFG approach provided valuable insights into the nature of the species composition of the developing vegetation on hard-coal mine spoil heaps. We suggest that it could be usefully applied in restoration practice in the future by facilitating the natural colonization of native species adapted to local conditions and thus retaining the local gene pool in these areas.
