on montane pasture and livestock management questions, especially yaks .
Arkhangai aimag is in the central area of the Khangai mountains, its headquarters,
Tsetserleg, is about 500 km west of Ulan Bator; its latitude is roughly
47° 30� N at 103° 15� E. It covers a range of ecological zones , including high
mountain , mountain steppe and steppe zones.
The average elevation is 1 700–1 850 m; mean annual precipitation 363 mm,
of which 80 percent falls in the period May to August; mean maximum temperature
in August is around 16.0°C, falling to -16.0°C in the December to
February period, with absolute maximum and minimum temperatures of 34.5
and -36.5°C. The aimag covers 55 300 km 2 , of which 41 000 km 2 is pasture ,
540 km 2 hay and 8 645 km 2 forest . The steppe zone, in the east of the province,
has the mildest climate: mean January temperature is -16°C (absolute minimum
-38°C) and July mean is 17.5°C (absolute maximum 35°C), with 98 to 125 frostfree
days. The main ecological zones in Arkhangai are shown in Table 7.6.
The high mountains are summer yak pasture that is not really accessible
to other species, although it can be used for horses. Because of the higher
humidity in the high zone, small ruminants suffer there from foot-rot. The
