Recent increases in livestock numbers have potentially reduced the capacity of habitats to sustain saiga because of forage or interference competition. We studied the potential for forage competition between saiga and domestic livestock in Shargyn Gobi, western Mongolia by quantifying diet overlaps using microscopic analysis of fecal samples. We collected 10 fecal samples from each of saiga, goat, sheep, horse, and camels in summer of 2011. We also established 105 plots at sightings of marked saiga antelope in June 2011 to determine vegetation community within saiga range. Each plot was subdivided into 5 adjacent 1 m2 square quadrats and the plants in them were surveyed. Onions or Allium appeared greater proportions in the diet composition of saiga, goat, and sheep. Diet composition of camels consisted mainly from shrubs, whereas Stipa was the dominantly found in the diet of horses. Among twenty-five plant species were recorded in the vegetation plots, Allium sp was the most frequently occurred species. The food habits of Mongolian saiga were quite similar to those of sheep and goats but were different from those of horses and camels. Our results suggest the saiga and sheep/goats would potentially be competitive on pasture as were suggested in similar study on Mongolian gazelle and argali sheep in Mongolia.
