Nomad Land Use and Livestock Grazing Impact

Amgalan Bayasgalan

Main Goal

The purpose of the grazing studies is to identify the impacts of pasture use and forest cutting on the dynamics of forest, steppe, riparian zones and streams in tributary valleys of Lake Hövsgöl and determine the optimal versions of sustainable resource use patterns.

Objectives

Within the framework of the main study that aims to identify the impacts of pasture use on steppe and riparian zones, collection of information of livestock grazing in every respect is the main goal of the livestock grazing study. These include:

  • Livestock Bite Count
  • Identify of pasture plants, their edibility and nutrition
  • Measure the Average Size of the Livestock Grazing Area of Each Family
  • Estimate Carrying Capacity
  • Create Pasture Map
  • Pasture management

Results and Discussion

Goats are dominant within the herd structure, a direct result of high cashmere costs. Livestock are active during evening and morning and in riparian zone. This directly relates to cool weather during evening.

Animals are more active during morning and evening in steppe zone. There is a positive relationship between water salinity and livestock number which directly relates to high grazing in riparian zone. Calculation of the records shows that 5 genera were dominants in most of the valleys, but with different percentage. These are: Artemisia, Potentilla, Carex, Festuca, and Leymus. They are used widely for livestock forage.
