Population structure and number dynamics of Great Bustard in the Federal Protected Area "Saratovski zakaznik". - V.G. Tabachishin, A.V. Khrustov, E.V. Zavialov. - Berkut. 13 (1). 2004. - P. 76-79.
Study of the population structure and number dynamics of Great Bustards in the Federal Protected Area “Saratovski Zakaznik” (Saratov region, Russia, a total area of 443 km2) was carried out in 1998, 2000 and 2001. The interannual fluctuations of the population are shown to be insignificant (152, 189, and 141 birds in 1998, 2000, and 2001, respectively). A trend in the dynamics has been revealed, it suggests promotion of breeding by means of control over crop rotation, introduction of an advanced agrotechnology, and other factors of agriculture provided that its intensity and profitability are preserved. Extension of the Federal Protected Area and further promotion of its nature-preservation status are desirable. [English].
