Site description
The IBA is situated in the central part of the Sypsynagash depression. The territory is a system of salt lakes, salt marshes, small fresh-water lakes and marshes (about 20 in total) and small rivers, situated in hilly herb-feather grass steppe, with solonchak complexes. Of the numerous salt lakes, the biggest are Urkash (5.5 x 3.5 km) and Jarsor (4 x 1.5 km). Both are in deep kettles with steep slopes and precipices up to 12-15 m deep. The maximum depth of water is 0.5 m even in spring. Along the shore-lines, there are some fresh-water springs with sparse reed and banks. The main source of water for this system is snow melt, so the water level changes during the summer and from year to year. The area between and around the lakes is natural grass steppe with patches of bushes (Spirea, Rosa etc.). There are small groves of aspen and birch near Jarsor lake. The region is little populated. There are only two villages within a radius of 20 km of the IBA, totalling about 1500 people.
