The Response of Grazed Vegetation in Relation to the Type of Landscape in the Mountain Rangelands, Tajikistan
The dataset reports on information collected to investigate the response of grazed vegetation in relation to landscape type in the mountain rangelands of Tajikistan over two seasons in 2016 (autumn and spring). Slopes facing the north and south, and grazed during different seasons were randomly selected and separated according to winter and summer pastures for each slope; summer pastures were grazed during the summer period, whereas the winter pastures were grazed during the winter period. The climate is moderately warm, with short warm winter and hot dry long summers, and the average annual rainfall ranges between 230-350 mm, whereas average yearly temperature ranges between 15.6-20 degrees Celsius. The dominant native species in the study site are the drought-tolerant white saxaul (Haloxylon persicum Bunge ex Boiss. & Buhse) while the Ferulafoetida (Bunge) Regel is widely expanded in areas with high load of livestock grazing. On each selected slope, five 100 m parallel transect lines, spaced 10 m apart were used to sample the vegetation. At every 10 m within each transect, 1 square meter quadrat was laid for monitoring biomass for annual plants, plant cover and density as well as species count. Inside the sub-quadrats, the standing crop was clipped at ground level and weighed before oven-drying at 85 degrees Celsius for 24 h, to estimate average standing crop calculated in kg/ha. To determine plant species cover, species were recorded along each transect using the line intercept method as described by whereas plant density was estimated by counting the number of individuals and dividing by the quadrat's area. Plant density, measured as plant/m2 and plant species coverage (%) were calculated.
